MEDAL OF HONOR

LIEUTENANT COLONEL LEO K. THORSNESS
UNITED STATES AIR FORCE

Rank and organization: Lieutenant Colonel (then Major), U.S. Air Force, 357th Tactical Fighter Squadron

Place and date: Over North Vietnam, 19 April 1967.

Entered service at: Walnut Grove, Minn.

Born: 14 February 1932, Walnut Grove, Minn.

Medal of HonorCitation: For conspicuous gallantry and intrepidity in action at the risk of his life above and beyond the call of duty. As pilot of an F- 105 aircraft, Lt. Col. Thorsness was on a surface-to-air missile suppression mission over North Vietnam. Lt. Col. Thorsness and his wingman attacked and silenced a surface-to-air missile site with air-to-ground missiles, and then destroyed a second surface-to-air missile site with bombs. In the attack on the second missile site, Lt. Col. Thorsness’ wingman was shot down by intensive antiaircraft fire, and the 2 crewmembers abandoned their aircraft. Lt. Col. Thorsness circled the descending parachutes to keep the crewmembers in sight and relay their position to the Search and Rescue Center. During this maneuver, a MIG-17 was sighted in the area. Lt. Col. Thorsness immediately initiated an attack and destroyed the MIG. Because his aircraft was low on fuel, he was forced to depart the area in search of a tanker. Upon being advised that 2 helicopters were orbiting over the downed crew’s position and that there were hostile MiGs in the area posing a serious threat to the helicopters, Lt. Col. Thorsness, despite his low fuel condition, decided to return alone through a hostile environment of surface-to-air missile and antiaircraft defenses to the downed crew’s position. As he approached the area, he spotted 4 MIG-17 aircraft and immediately initiated an attack on the MlGs, damaging 1 and driving the others away from the rescue scene. When it became apparent that an aircraft in the area was critically low on fuel and the crew would have to abandon the aircraft unless they could reach a tanker, Lt. Col. Thorsness, although critically short on fuel himself, helped to avert further possible loss of life and a friendly aircraft by recovering at a forward operating base, thus allowing the aircraft in emergency fuel condition to refuel safely. Lt. Col. Thorsness’ extraordinary heroism, self-sacrifice, and personal bravery involving conspicuous risk of life were in the highest traditions of the military service, and have reflected great credit upon himself and the U.S. Air Force.

Air Force Cross
Air Force Cross

The President of the United States of America, authorized by Title 10, Section 8742, United States Code, takes pleasure in presenting the Air Force Cross to Captain Harold Eugene Johnson (AFSN: 0-3116556/42372A), United States Air Force, for extraordinary heroism as Electronics Warfare Officer of an F-105 aircraft of the 357th Tactical Fighter Squadron, 355th Tactical Fighter Wing, Tuy Hoa Air Base, Vietnam, engaged in a pre-strike, missile suppression mission over North Vietnam on 19 April 1967. On that date, Captain Johnson guided his pilot in attacking and destroying a surface-to-air missile installation with an air-to-ground missile. Through his technical skill, he immediately detected a second missile complex and guided the pilot into visual contact. Diving into a deadly barrage of anti-aircraft fire, his aircraft bombed and successfully destroyed this site. In the attack on this second missile site, a wingman was shot down by the intense anti-aircraft fire, and the crew members were forced to abandon their aircraft. Flying through hostile missile threats, Captain Johnson’s aircraft engaged and destroyed a MiG-17 while attacking a superior MiG force. He aided in the rescue efforts for the downed crew, engaged additional MiGs, and damaged one in the encounter. Through his extraordinary heroism, superb airmanship, and aggressiveness, Captain Johnson has reflected the highest credit upon himself and the United States Air Force.

(U.S. Air Force)

A description of the air battle follows:

The first MiG kill of the day was recorded by Maj. Leo K. Thorsness, pilot, and Capt. Harold E. Johnson, Electronic Warfare officer (EWO), flying an F-105F. Thorsness’ flight consisted of four F-105F Wild Weasel aircraft, each plane being manned by a pilot and EWO and being specially equipped to locate and attack SAM sites. The flight was ahead of the main strike force and was committed to suppress SAM activity in the target area. About 8 to 10 MiG-17s attacked as the flight prepared to strike a SAM radar site with Shrike air-to-ground missiles. The Thorsness flight split up into three parts: the third and fourth aircraft entered into separate MiG engagements while Thorsness and his wingman continued the attack against the radar. The time was then about 4:55 p.m. Johnson provides an account of the encounter:

We found and delivered our ordnance on an occupied SAM site. As we pulled off the site heading west, Kingfish 02 ¹ called that he had an overheat light. He also headed west, and the crew, Majors Thomas M. Madison, pilot, and Thomas J. Sterling, EWO, had to eject from their aircraft. We headed toward them by following the UHF-DF steer we received from their electronic beepers and saw them in the chutes. . .

As we circled the descending crew, we were on a southerly heading when I spotted a MiG-17 heading east, low at out 9 o’clock position. I called him to the attention of Major Thorsness. . . .

Thorsness continued the story:

The MiG was heading east and was approximately 2,500 feet mean sea level. We were heading southeast and at 8,000 feet MSL. I began “S” turning to get behind the MiG. After one and a half “S” turns the MiG had progressed from the foothills over the delta southwest of Hanoi. The MiG turned to a northerly heading, maintaining approximately the same altitude and airspeed. Captain Johnson continued to give me SAM bearings, SAM-PRF [pulse recurrence frequency] status and launch indications as I continued to maneuver to attain a 6 o’clock position on the MiG.

The first burst of approximately 300 rounds of 20 mm was fired from an estimated 2,000–1,500 feet in a right hand shallow pursuit curve, firing with a cased sight reticle. No impacts were observed on the MiG. Within a few seconds we were in the 6 o’clock position with approximately 75 to 100 knots overtake speed. I fired another burst of approximately 300 rounds of 20 mm. I pulled up to avoid both the debris and the MiG. While pulling up I rolled slightly to the right, then left. The MiG was approximately 100 feet low and to our left, rolling to the right. The two red stars were clearly discernible, one on top of each wing, and several rips were noted on the battered left wing. We continued to turn to the left and after turning approximately 130° again sighted the MiG, still in a right descending spiral. Just prior to the MiG’s impacting the ground, Captain Johnson sighted a MiG-17 at our 6:30 position approximately 2,000 feet back. I pulled into a tighter left turn, selected afterburner, and lowered the nose. I again looked at the crippled MiG, saw it impact the ground in what appeared to be a rice field. After confirming the MiG had in fact impacted the ground I made a hard reversal and descended very near the ground, heading generally westerly into the foothills.

Thorsness then left the battle area, but returned after refueling to provide rescue combat air patrol during the search for his wingman’s aircrew. Thorsness and Johnson attacked another MiG and scored some damaging hits before they were themselves attacked by other MiG-17s. Although it is highly probable that Thorsness and Johnson destroyed a second MiG, this kill was not confirmed.

Eleven days later, 30 April 1967, Major Thorsness and Captain Johnson were shot down by an AA-2A Atoll heat-seeking missile fired by a MiG-21 fighter piloted by Vũ Ngọc Đỉnh, 921st Fighter Regiment, Vietnam People’s Air Force. They ejected but were captured. Both men were held as Prisoners of War until 4 March 1973.

Colonel Leo Keith Thorsness, United States Air Force (Retired) died Tuesday, 2 May 2017, at St. Augustine, Florida. He was 85 years of age.

19 April 1960: Grumman Aircraft Engineering Corporation test pilot Robert K. Smyth made the first flight of the prototype YA2F-1 Intruder, Bu. No. 147864, at the Grumman Peconic River Airport (CTO), Calverton, Long Island, New York. During the flight, Smyth climbed to 15,000 feet (4,572 meters). The landing gear remained extended during the flight. At one point, Smyth attempted to retract it, but a malfunction was indicated, so they remained down and locked. The first flight lasted one hour.

During follow-on flights, Bob Smyth and project test pilot Ernie von der Heyden (who flew the photo-chase plane during the first flight) alternated left and right seats.

Bu. No. 147864 was painted gray with U.S. Navy markings before being accepted by the Navy on 29 April 1960. The airplane was lost 31 May 1960.

Eight Grumman YA2F-1 Intruders were built for the test program.  They were redesignated A-6A Intruder in 1962.

The Grumman A-6A Intruder was a carrier-based, all-weather attack bomber powered by two turbojet engines. It was operated by a pilot and a bombardier/navigator, or “b/n,” in a side-by-side cockpit. The wings were slightly swept.

The A2F-1 was 53 feet, 3 inches (16.231 meters) long with a wing span of 53 feet, 0 inches (16.154 meters) and overall height of 15 feet, 2 inches (4.623 meters). The wings had a total area of 528.9 square feet (49.14 square meters) and were swept aft to 25° at 25% chord. The aircraft had an empty weight of 23,412 pounds (10,620 kilograms) and maximum takeoff weight of 53,278 pounds (24,166 kilograms).

The prototypes were powered by two Pratt & Whitney J52-P-6 turbojet engines which had previously been used on the North American Aviation AGM-28 Hound Dog cruise missile. The J52 was a two-spool, axial-flow turbojet with a 12-stage compressor section (5 low- and 7 high-pressure stages) and 2-stage (1 high- and 1-low pressure stages). The engines had a normal power rating of 7,500 pounds of thrust (33.36 kilonewtons) at 11,400 r.p.m., and a maximum of 8,500 pounds (37.81 kilonewtons) at 11,650 r.p.m. The J52-P-6 was 31 inches (0.787 meters) in diameter, 127 inches (3.226 meters) long, and weighed 2,056 pounds (933 kilograms) The engine incorporated an exhaust nozzle that could be swiveled downward 23° to assist in short field takeoffs.

The A-6A had a cruise speed of 429 knots (493 miles per hour/795 kilometers per hour) at 44,450 feet (13,548 meters) and a maximum speed of 566 knots (651 miles per hour/1,048 kilometers per hour) at Sea Level. The service ceiling was 48,250 feet (14,707 meters), and the maximum range was 2,061 nautical miles (2,372 statute miles/3,817 kilometers).

The initial production Intruders could carry 18,000 pounds ( kilograms) of bombs on hardpoints under the wings. It could also carry AIM-9 Sidewinder air to air, or AGM-12 Bullpup air to ground missiles. “Special Weapons” that could be carried included Mk. 28 or Mk. 43 thermonuclear bombs.

The Intruder was a very successful combat aircraft with 693 built in attack, tanker and electronic warfare variants. They remained in service with the United States Navy until 1997.

19 April 1955:¹ Lockheed test pilot Herman Richard (“Fish”) Salmon was flying the second prototype Lockheed XF-104 interceptor, 53-7787, conducting tests of the General Electric T171 Vulcan gun system.

At 47,000 feet (14,326 meters), Salmon fired two bursts from the T171. On the second burst, vibrations from the gun loosened the airplane’s ejection hatch, located beneath the cockpit, resulting in explosive decompression.

The Associated Press reported:

Test Pilot Leaps From New Jet

     INYOKERN, Calif., April 20 (AP)—Herman R. (Fish) Salmon, former racing pilot and now a top test pilot, bailed safely from one of the Air Force’s hot new F104 jet fighters over the Mojave dessert[sic]Tuesday.

He was  spotted on the desert after a two-hour search by military planes and brought to the Naval ordinance [sic] test station here for a physical examination. A preliminary checkup indicated he was not injured.

     Salmon, 41, was on a routine test flight when he hit the silk. Authorities gave no hint what happened to the supersecret plane to make the bailout necessary. The craft’s height at the time it was abandoned was not given. The plane’s top speed has been unofficially estimated at 1,200 m. p. h.

     Wreckage of the F104, one of two prototypes now being tested by Lockheed Aircraft Corp. for the Air Force, was found several miles south of the China Lake area.

     A Lockheed spokesman said Salmon, of Van Nuys, Calif., was spotted by a search plane and apparently picked up by a Navy helicopter and flown here. Salmon took off on the test flight from Palmdale, about 70 miles south of here.

— Reno Evening Gazette, Volume LXXIX, Number 21, Wednesday, 20 April 1955, Page 24 at Columns 5–7.

Fish Salmon was wearing a David Clark Co. T-1 capstan-type partial-pressure suit and International Latex Corporation (I.L.C. Dover) K-1 helmet for protection in just such an emergency. The capstans are pneumatic tubes surrounded by fabric lacings, running along the arms, torso and legs. As the tubes inflated, the lacings pulled the fabric of the suit very tight and applied pressure to his body as a substitute for normal atmospheric pressure. The partial-pressure garment also enclosed his head, with a fiberglass helmet and a clear visor or face plate providing for vision.

The sudden loss of cabin pressure and drop to subfreezing temperatures caused Salmon’s face plate to fog over. Inflating air bladders pushed his helmet high on his head.  The cockpit was filled with dust, fiberglass insulation and other debris. All this restricted his visibility, both inside and outside the airplane. The very tight pressure suit restricted his movements.

Fish Salmon cut the throttle, opened the speed brakes and began a descending turn to the left to reach a lower altitude. By the time he had reached 15,000 feet (4,572 meters) he had been unable to find a place on the desert floor to make an emergency landing. It was time to leave the crippled XF-104.

At 250 knots (288 miles per hour/463 kilometers per hour) the ejection seat fired Salmon out of the bottom of the cockpit. He had to open his parachute manually (the seat timer did not operate) and he made a safe landing.

The XF-104 had a downward-firing ejection seat, intended to avoid the airplane's tall vertical tail. Production aircraft used an upward-firing seat. (Lockheed)
The XF-104 had a downward-firing ejection seat, built by Stanley Aviation Inc. It was intended to avoid the airplane’s tall vertical tail. Later production aircraft used an upward-firing Martin-Baker seat. This airplane is the second prototype XF-104, 53-7787. (Lockheed Martin)

The prototype XF-104 impacted the desert approximately 73 miles (117 kilometers) east-northeast of Edwards Air Force Base. It was completely destroyed. Fish Salmon landed about 2 miles (3.2 kilometers) away. He was found two hours later and rescued by an Air Force helicopter.

Occasionally, a satisfied user thanked the researchers at the Aero Medical Laboratory. One of these was Lockheed test pilot Herman R. “Fish” Salmon. On April 14, 1955, ¹ Salmon was flying the second XF-104 (53-7787) at 47,500 feet while wearing a T-1 suit, K-1 helmet, and strap-fastened boots. As he triggered the General Electric M61 Vulcan 20 mm cannon for a test firing, severe vibrations loosened the floor-mounted ejection hatch and the cockpit explosively depressurized at the same time as the engine flamed out. The suit inflated immediately. Repeated attempts to restart the engine failed, and Salmon ejected at 15,000 feet. Fish reported, “I landed in a field of rocks ranging from one foot to five feet in diameter. My right arm was injured and my head struck a rock. The K-1 helmet hard shell was cracked, but there was no injury to my head. It took me 10 to 15 minutes to get out of the suit with my injured arm. Rescue was effected by helicopter approximately two hour after escape.” Salmon reported that the K-1 helmet was excellent for rugged parachute landings, and his only complaint was that the visor may impair vision at extreme altitudes.”

There were two Lockheed XF-104 prototypes. Initial flight testing was performed with 083-1001 (USAF serial number 53-7786). The second prototype, 083-1002 (53-7787) was the armament test aircraft. Both were single-seat, single-engine supersonic interceptors. The XF-104 was 49 feet, 2 inches (14.986 meters) long with a wingspan of 21 feet, 11 inches (6.680 meters) and overall height of 13 feet, 6 inches (4.115 meters). The prototypes had an empty weight of 11,500 pounds (5,216 kilograms) and maximum takeoff weight of 15,700 pounds (7,121 kilograms).

The production aircraft was planned for a General Electric J79 turbojet but that engine would not be ready soon enough, so both prototypes were designed to use a Buick-built J65-B-3, a licensed version of the British Armstrong Siddeley Sapphire turbojet engine. XF-104 53-7787 had been built with an afterburning Wright J65-W-7 turbojet, rated at 7,800 pounds of thrust, and 10,200 pounds of thrust with afterburner. The J65 was a single-shaft axial-flow turbojet with a 13-stage compressor, annular combustion chamber, and 2-stage turbine.

The XF-104 had a maximum speed of 1,324 miles per hour (2,131 kilometers per hour), a range of 800 miles (1,287 kilometers) and a service ceiling of 50,500 feet (15,392 meters).

The General Electric T171 Vulcan was a prototype 6-barrelled 20 mm “Gatling Gun” automatic cannon. The barrels were rotated at high speed by a hydraulic drive. The gun is capable of firing 6,000 rounds per minute. The initial production version was designated M61. The cannon system was installed in a weapons bay on the left side of the F-104, between the cockpit and engine intakes. The production F-104C carried 750 rounds of ammunition.

The Lockheed F-104 Starfighter was armed with an electrically-powered General Electric M61 Vulcan 6-barrel rotary cannon, or “Gatling Gun.” The technician is carrying a linked belt of 20 mm cannon shells. (René Francillon Photo Collection, San Diego Air & Space Museum Archives, Catalog #: 17_000199)

The first prototype Lockheed XF-104, 53-7786, was also destroyed, 11 July 1957, when the vertical fin was ripped off by uncontrollable flutter. The pilot, William C. Park, safely ejected.

¹ Reliable sources give the date of this incident as both 14 April and 19 April. Contemporary news reports, published Wednesday, 20 April 1955, say that the accident took place “yesterday” and “Tuesday,” suggesting that the correct date is 19 April.

19 April 1919: Captain Earl French White, Air Service, United States Army, and H.M. Schaffer, “his mechanician,” took off from Ashburn Aviation Field, Chicago, Illinois, at 9:50 a.m, Central Standard Time, in the Dayton-Wright DH-4, Air Service serial number A.S. 30130. At 5:40 p.m., Eastern Standard Time, the airplane and its two-man crew landed at Hazelhurst Field, Mineola, Long Island, New York. They flew 738.6 miles (1,188.7 kilometers) in 6 hours, 50 minutes at an average speed of approximately 106 miles per hour (170.6 kilometers per hour).

The New York Times reported the event on its front page on the following day:

. . . Captain White had great difficulty in taking to the air in the soft ground of Ashburn Field, the take-off grounds approved by the Aero Club of Illinois. The ground there was soft and the heavy army plane, with her load of more than 190 gallons [719.2 liters] of gasoline, cut into it deeply, but after the aviator had had his plane dragged to a drier and harder spot in the field he managed to take to the air.

Circling over Chicago, Captain White ascended to a height of more than 10,000 feet [3,048 meters] and throughout his flight he did not go below this level until he was ready to land, and at intervals he flew as high as 12,000 feet [3,658 meters] He followed the route of the New York Central Railroad for the greater part of the distance, and cities along the route reported seeing him flying at great height and at high speed.

About 5 o’clock yesterday persons visiting on the ships of the Atlantic Fleet in the Hudson River and pedestrians on Riverside Drive saw a dark blue airplane come down from the north at high speed, turn sharply to the east when it was about opposite Fiftieth Street and then gradually came to a lower level as it circled about over the city.

All thought it was only one of the many airplanes and seaplanes that take their daily practice flights over the Hudson River and Manhattan Island, but it was Captain White and the first Chicago-New York non-stop airplane, bearing the army number 30,130.

Plane a Standard Army Machine.

After sailing over the city for about ten minutes, Captain White turned his machine toward the army aviation field at Mineola, where he landed at about 5:40 o’clock. Colonel Archibald Miller, Director of Aviation in the Department of the East and one of the commanders of the Hazelhurst Field, was waiting there to meet captain White and his mechanician, H.M. Schaefer, and they were taken to the field headquarters where an informal reception was held.

Officers at the Hazelhurst Field said that the biplane used by Captain White in his flight was one of the standard De Havilland Four machines constructed for the use of the army in France, and that it was equipped with a twelve-cylinder Liberty motor of about 400 horsepower.

— The New York Times, 20 April 1919, Page 1, Column 4, and continued on Page 9.

Captain White’s flight was observed by members of the Aero Club of America. The time of White’s departure from Chicago was telegraphed to New York. The flight was certified by the Aero Club, which represented the Fédération Aéronautique Internationale (FAI) within the United States. This was the first non-stop flight between Chicago and New York, and was the longest non-stop flight that had been made anywhere in the world up to that time.

The Dayton-Wright Airplane Company DH-4 was a variant of the British Airco DH.4, designed by Geoffrey de Havilland (and commonly known as the de Havilland DH.4). It was a two-place, single-engine biplane intended as a bomber, but served in virtually every capacity during World War I and the years following.

The Airco DH.4 had a crew of two. It was 30 feet, 8 inches (9.347 meters) long with a wingspan of 43 feet, 4 inches (13.208 meters) and height of 11 feet (3.353 meters). Empty weight was 2,387 pounds (1,085 kilograms) and loaded weight was 3,472 pounds (1,578 kilograms). British-built DH.4s were powered by a 1,239-cubic-inch-displacement (20.32 liter) liquid-cooled Rolls-Royce Eagle overhead cam 60° V-12 engine which produced 375 horsepower. A gear-reduction system kept propeller r.p.m. below engine speed for greater efficiency.

The Liberty L12 aircraft engine was designed by Jesse G. Vincent of the Packard Motor Car Company and Elbert J. Hall of the Hall-Scott Motor Company. It was a  water-cooled, normally-aspirated, 1,649.336-cubic-inch-displacement (27.028 liter) Liberty L-12 single overhead cam (SOHC) 45° V-12 engine with a compression ratio of 5.4:1. The Liberty produced 408 horsepower at 1,800 r.p.m. The L-12 as a right-hand tractor, direct-drive engine and it turned turned a two-bladed fixed-pitch wooden propeller. The Liberty 12 was 5 feet, 7.375 inches (1.711 meters) long, 2 feet, 3.0 inches (0.686 meters) wide, and 3 feet, 5.5 inches (1.054 meters) high. It weighed 844 pounds (383 kilograms). This engine was produced by Ford Motor Company, as well as the Buick and Cadillac Divisions of General Motors, The Lincoln Motor Company (which was formed by Henry Leland, the former manager of Cadillac, specifically to manufacture these aircraft engines), Marmon Motor Car Company and Packard. Hall-Scott was too small to produce engines in the numbers required.

Dayton-Wright DH-4, U.S. Army Air Service serial number A.S. 30130, was built at the Dayton-Wright Airplane Company factory in 1918. It was used for engineering tests at McCook Field, and carried project number P78 painted on its rudder. What became of the airplane after Captain White left it at Hazelhurst Field is not known.

American-built DH.4 airplanes were produced by the Boeing Airplane Company, Dayton-Wright Airplane Company, Fisher Body Corporation, and Standard Aircraft Corporation. Most were powered by the Liberty L12 engine. Following World War I, many DH-4s were rebuilt by Boeing and Atlantic Aircraft. An improved version, the DH-4M, used a tubular steel framework instead of the usual wood construction. DH-4s remained in service with the United States Army as late as 1932. At McCook Field, Dayton, Ohio, the U.S. Army’s aviation engineering center, DH-4s were commonly used as test beds for engines and other aeronautical equipment.

Hazelhurst Field was renamed Roosevelt Field in 1920, in honor of Lieutenant Quentin Roosevelt, 95th Aero Squadron, son of former President Theodore Roosevelt, who was killed in aerial combat during World War I.

Earl French White was born at Minneapolis, Minnesota, 12 July 1888. He was the son of Clarence Otis White, a manufacturing engineer, and Harriet (“Hattie”) Isabel French White. He enlisted in the United States Army, 8 October 1910, and was assigned to the 11th Cavalry Regiment at Fort Myer, Virginia. In 1915 he transferred to the Aviation Section, Signal Corps. He completed flight training 27 March 1917.

Earl French White was commissioned as a Captain, Aviation Section, Signal Corps, United States Army, on 8 November 1917, and qualified as a Reserve Military Aviator in January 1918. In August 1918, Captain White was assigned to Wilbur Wright Field, Dayton, Ohio, and later, the Technical Flying Field in Dayton.

On 1 July 1919, Captain White was one of three pilots who flew the inaugural U.S Air Mail Service route from New York City, New York, to Chicago, Illinois. Captain White flew a DH-4 on the route segment from Bellefonte, Pennsylvania, to Cleveland, Ohio. He carried 6 pouches containing 330 pounds (150 kilograms) of mail, and arrived at Cleveland at 9:30 a.m.

Earl French White married Miss Mary Esther Edmondson at Sarasota, Florida, 26 February 1923. Miss Edmondson had served in France during World War I as a civilian aide with the American Red Cross. They would have a daughter, Patricia.

From 14 April 1923 to 30 June 1925, White flew for the U.S. Air Mail Service at Bellefonte, Pennsylvania, North Platte and Omaha, Nebraska, and Cheyenne, Wyoming. He flew scheduled night air mail from July 1924 to July 1925.

From 1928 to 1931, Earl White was a pilot for Pan American Airways in the Caribbean area.

In 1935, White was employed by William Kissam Vanderbilt II to fly his Sikorsky S-43 amphibian, NC-16825. Vanderbilt described White as “one of the most reliable and resourceful aviators in the game.”

William K. Vanderbilt II’s Sikorsky S-43 amphibian, NC-16925, serial number 4314. This airplane was impressed by the U.S. Army Air Corps 14 September 1941 and designated OA-11, 42-001. It was destroyed in a crash landing at Corcorite Bay, Trinidad, 5 November 1941. All five persons on board were killed.

As of 11 February 1937, White had logged a total of 5,370 hours, 50 minutes, of flight time.

During World War II, White was employed as a delivery pilot for the Consolidated Aircraft Corporation.
