Jet Airliner Crosses U.S. At Record Clip

Seattle-To-Baltimore Flight Made In 3 Hours, 48 Minutes

WASHINGTON, March 12 (AP) A Boeing 707 jet passenger plane set a new transcontinental speed record for commercial aircraft yesterday, flying the 2,325 miles from Seattle to Baltimore in 3 hours and 48 minutes.

At one point it attained a speed of 698 miles an hour.

A.M. (Tex) Johnston, Boeing chief of flight tests, said he would fly back to Seattle tomorrow with stops at Chicago’s O’Hare Airport and at Denver. He planned a series of local flights for congressmen, Pentagon officials and experts.

The big plane averaged 612 miles an hour for its Puget Sound-to-Chesapeake Bay flight, and sliced 10 minutes off the unofficial transport plane record it set between Seattle and Washington, D.C., in 1955.

There were 52 persons aboard, all but 20 of them newsmen.

‘Jet Stream’ Helps

The 707 left Boeing Field at 10:06 a.m., EST. East of Spokane at 31,000 feet, it hit the “jet stream,” a vast windstream with speeds of up to 125 miles an hour.

These winds enabled the plane to attain supersonic speeds in relation to the ground over northwestern Montana and northern Idaho. However, the plane was actually in subsonic flight and did not break the “sound barrier.”

While in the jet stream, the plane’s peak air speed was 596 miles an hour, but at one point the stream boosted this by 102 miles an hour, for a top speed of 698 in relation to the ground.

Fighter Holds Record

The fastest unofficial transcontinental crossing listed by the Defense Department: 715 mph for the 2,700 miles from Riverside, Calif., to Boston last Jan. 25, by a Boeing B-47 bomber.

The 707 is to be delivered to its first airline buyers—Pan American and American—late next year and early in 1959.

The plane’s cost varies from 4½ to 5½ million dollars, depending on size and range, Various models will carry from 120 to 162 passengers.

Boeing had risked $16,000,000 in a private venture to build the Dash 80 in order to demonstrate its capabilities to potential civilian and military customers, while rivals Douglas and Lockheed were marketing their own un-built jet airliners. Put into production as the U.S. Air Force KC-135A Stratotanker air refueling tanker and C-135 Stratolifter transport, a civil variant was also produced as the Boeing 707 Stratoliner, the first successful jet airliner. Though they look very similar, the 707 is structurally different than the KC-135 and has a wider fuselage.

The prototype Boeing Model 367-80 was operated by a pilot, co-pilot and flight engineer. The airplane’s wing was mounted low on the fuselage and the engine nacelles were mounted on pylons under the wing, as they were on Boeing’s B-47 Stratojet and B-52 Stratofortress. The wings and tail surfaces were swept to 35° at 25% chord, and had 7° dihedral. The Dash 80 was 127 feet 10 inches (38.964 meters) long with a wingspan of 129 feet, 8 inches (39.522 meters) and overall height of 38 feet (11.582 meters). The tail span is 39 feet, 8 inches (12.090 meters). The empty weight of the 367-80 was 75,630 pounds (34,505 kilograms) and the gross weight, 190,000 pounds (86,183 kilograms).

N70700 was powered by four Pratt & Whitney Turbo Wasp JT3C engines. This engine is a civil variant of the military J57 series. It is a two-spool, axial-flow turbojet engine with a 16-stage compressor and 2-stage turbine. The JT3C-6 (used in the first production 707s) was rated at 11,200 pounds of thrust (49.82 kilonewtons), and 13,500 pounds (60.05 kilonewtons) with water/methanol injection). The JT3C is 11 feet, 6.6 inches (3.520 meters) long, 3 feet, 2.9 inches (0.988 meters) in diameter, and weighs 4,235 pounds (1,921 kilograms).

These gave the 367-80 a cruise speed of 550 miles per hour (885 kilometers per hour) and a maximum speed of 0.84 Mach (582 miles per hour, 937 kilometers per hour) at 25,000 feet (7,620 meters). The service ceiling was 43,000 feet (13,106 meters). Its range was 3,530 miles (5,681 kilometers).

Boeing continued to use the 367–80 for testing, finally retiring it 22 January 1970. At that time, its logbook showed 2,346 hours, 46 minutes of flight time (TTAF). It was flown to Davis-Monthan Air Force Base, Tucson, Arizona, and placed in storage. In 1990, Boeing returned it to flyable condition and flew it back it to Renton where a total restoration was completed. Many of those who had worked on the Dash 80, including Tex Johnston, were aboard.

The pioneering airplane was presented to the Smithsonian Institution and is on display at the National Air and Space Museum, Steven V. Udvar-Hazy Center. The Boeing 367-80 was designated an International Historic Mechanical Engineering Landmark by the American Society of Mechanical Engineers.

11 March 1918: 1st Lieutenant Paul Frank Baer, Air Service, United States Army, assigned to the103rd Aero Squadron, American Expeditionary Forces, flying a SPAD S.VII C-1 chasseur, shot down an enemy Albatros D, near Cerney-les-Reims, France. For this and other actions, Lieutenant Baer was awarded the Distinguished Service Cross.

The President of the United States of America, authorized by Act of Congress, July 9, 1918, takes pleasure in presenting the Distinguished Service Cross to First Lieutenant (Air Service) Paul Frank Baer, United States Army Air Service, for extraordinary heroism in action while serving with 103d Aero Squadron, 3d Pursuit Group, U.S. Army Air Service, A.E.F., on 11 March 1918. First Lieutenant Baer attacked, alone, a group of seven enemy pursuit machines, destroying one, which fell near the French lines northeast of Reims, France. On 16 March 1918, he attacked two enemy two-seaters, one of which fell in flames in approximately the same region.

War Department, General Orders No. 128 (1919)

Lieutenant Baer was the first United States airman to receive the Distinguished Service Cross.

Lieutenant Baer is officially credited by the United States Air Force with 7.75 enemy airplanes shot down between 11 March and 22 May 1918, and he claimed an additional 7. (Credit for two airplanes was shared with four other pilots.) After shooting down his eighth enemy airplane on 22 May 1918, Baer and his SPAD S.XIII C.1 were also shot down. He was seriously injured and was captured by the enemy near Armentières and held as a Prisoner of War. At one point, Baer was able to escape for several days before being recaptured.

For his service in World War I, 1st Lieutenant Paul Frank Baer was awarded the United States’ Distinguished Service Cross with one oak leaf cluster (a second award). He was appointed Chevalier de la Légion d’honneur by Raymond Poincaré, the President of France. He was also awarded the Croix de Guerre with seven palms.

Biplan SPAD de chasse monoplace S.VII (rcgroups.com)

The Société Pour L’Aviation et ses Dérivés SPAD S.VII C.1 was a single-place, single-engine, two-bay biplane chasseur (fighter). The airplane was 19 feet, 11 inches (5.842 meters) long, with a wingspan of 25 feet, 7¾ inches (7.817 meters) and overall height of 7 feet, 2 inches (2.184 meters). It had a maximum gross weight of 1,632 pounds (740 kilograms).

The SPAD VII was initially powered by a water-cooled, normally-aspirated, 11.762 liter (717.769 cubic inches) Société Française Hispano-Suiza 8Aa, a single overhead camshaft (SOHC) 90° V-8 engine with a compression ratio of 4.7:1. The 8Aa produced 150 horsepower at 2,000 r.p.m. By early 1918, the S.VII’s engine was upgraded to the higher-compression 8Ab (5.3:1), rated at 180 horsepower at 2,100 r.p.m. These were right-hand tractor, direct-drive engines which turned a two-bladed fixed-pitch wooden propeller.

The SPAD VII had a maximum speed of 119 miles per hour (192 kilometers per hour). The 8Ab engine increased this to 129 miles per hour (208 kilometers per hour). The service ceiling was 17,500 feet (5,334 meters).

Armament consisted of a single air-cooled Vickers .303-caliber (7.7 × 56 millimeter) machine gun, synchronized to fire forward through the propeller arc.

The SPAD S.VII was produced by nine manufacturers in France and England. The exact number of airplanes built is unknown. Estimates range from 5,600 to 6,500.

The airplane in this photograph is a SPAD S.VII C.1, serial number A.S. 94099, built by Société Pour L’Aviation et ses Dérivés, and restored by the 1st Fighter Wing, Selfridge Air Force Base, Michigan. It is in the collection of the National Museum of the United States Air Force, Wright-Patterson Air Force Base, Ohio.

10 March 1967: Captain Max C. Brestel, United States Air Force, a pilot assigned to the 354th Tactical Fighter Squadron, 355th Tactical Fighter Wing at Takhli Royal Thai Air Force Base, was flying a Republic F-105D-31-RE Thunderchief fighter-bomber, serial number 62-4284. His call sign was “Kangaroo 03.” During an attack on the Thai Nguyen Steel Mill, the single most heavily-defended target in North Vietnam, Captain Brestel engaged and shot down two enemy MiG-17 fighters.

This was the first time during the Vietnam War that an American pilot shot down two enemy airplanes during the same mission. The following description is from an official U.S. Air Force history:

Brestel’s aerial victories became the first USAF double kill of the conflict. At the time, he was flying the third Thunderchief in a flight of four and was tasked with suppressing flak in and around the Thai Nguyen steel mill and supporting other F-105 strike forces. Brestel relates how his two victories came about:

“We proceeded to the target via the Red River to a point north of the target, where we turned south. Numerous SAM and MiG warnings had been transmitted. Also, the 388th Wing, which had preceded us on the target, had encountered MiGs.

“As the flight pulled up to gain altitude for delivering our ordnance, I sighted two MiG-21s making a pass at Col. Gast [Lt. Col. Philip C. Gast, the flight leader] from his 4 o’clock position. I was in lead’s 8:30 o’clock position. I broke toward the MiGs and passed across his tail. They broke off the attack and I continued on my dive delivery. Flak was normal for the area. We delivered our ordnance as planned.”

As the flight pulled out at an altitude of approximately 3,000 to 4,000 feet, Gast called MiGs at 2 o’clock low. ‘Let’s go get them,’ he urged. ‘I’m with you,’ Brestel acknowledged as he spotted the flight of four MiG-17s in staggered trail heading north at approximately 1,500 feet. Behind them was another flight of four. Brestel’s narrative continues:

“I observed all MiGs light their afterburners. Colonel Gast began firing at one of the first two MiGs. I observed the second two begin to fire at Colonel Gast. I called a break and closed within 300–500 feet of the number four MiG. I fired an approximate 2½ second burst at him as he was in a right turn. I observed hits in the wing and fuselage. The MiG reversed into a left turn. I fired another 2½ second burst into him, observing hits in the left wing, fuselage and canopy, and a fire in the left wing root. The aircraft rolled over and hit the ground under my left wing. I then closed 300 feet on the number three MiG, which was firing at Colonel Gast. He was in a right turn and again I fired a 2½ second burst, observing hits in wing, fuselage, etc. He also reversed to the left and I fired another 2½ second burst, observing more hits and pieces flying off the aircraft. The aircraft appeared to flip back up over my canopy and disappeared behind me. we broke off the engagement at this time after approximately 1½ to 2 minutes of combat. A SAM was fired at us and more flak as we exited the area.

“I know I destroyed the first MiG, as I saw him crash. I did not see the pilot bail out and doubt if he was alive, since hits were observed in the cockpit and the canopy broke up. My wingman, Lt. Weskamp [1st Lt. Robert L. Weskamp] also observed the MiG hit the ground.

“I feel I also destroyed the second MiG, as the range was the same and hits were observed in the same areas, i.e., fuselage, wings, etc. Also, his last maneuver could not be considered normal. The aircraft appeared to be in a violent pitch-up or tumble and out of control… However, because he pitched up over and behind me, I did not see him strike the ground.”

Brestel was given credit for destroying both MiGs.

Vietnamese sources identified one of the downed MiG-17 fighters as being of Z Group, Korean People’s Air Force, flown by Kim Quang Wook, who was killed.

The F-105D Thunderchief is 64 feet, 5.3 inches (19.642 meters) long with a wingspan of 34 feet, 11.2 inches (10.648 meters) and overall height of 19 feet, 8.4 inches (6.005 meters). The total wing area was 385 square feet (35.8 square meters). Its wings were swept 45° at 25% chord. The angle of incidence was 0° and there was no twist. The wings had 3° 30′ anhedral. The F-105D-31 has an empty weight of 26,855 pounds (12,181 kilograms) and a maximum takeoff weight of 52,838 pounds (23,967 kilograms).

The Thunderchief was powered by one Pratt & Whitney J75-P-19W engine. The J75 is a two-spool axial-flow afterburning turbojet with water injection. It has a 15-stage compressor section (8 low- and and 7 high-pressure stages) and 3-stage turbine section (1 high- and 2 low-pressure stages.) The J75-P-19W is rated at 14,300 pounds of thrust (63.61 kilonewtons), continuous power; 16,100 pounds (71.62 kilonewtons), Military Power (30-minute limit); and Maximum Power rating of 24,500 pounds (108.98 kilonewtons) with afterburner (15-minute limit). The engine could produce 26,500 pounds of thrust (117.88 kilonewtons) with water injection, for takeoff. The J75-P-19W is 21 feet, 7.3 inches (6.586 meters) long, 3 feet, 7.0 inches (1.092 meters) in diameter, and weighs 5,960 pounds (2,703 kilograms).

The maximum speed of the F-105D was 726 knots (835 miles per hour/1,345 kilometers per hour) at Sea Level (Mach 1.09) and 1,192 knots (1,372 miles per hour (2,208 kilometers per hour) at 36,089 feet (11,000 meters) (Mach 2.08). The combat ceiling was 51,000 feet (15,545 meters). The F-105D’s combat radius varied with the type of mission from 277 to 776 nautical miles (319–893 statute miles/513–1,437 kilometers). The maximum ferry range was 1,917 nautical miles (2,206 statute miles/3,550 kilometers).

The F-105D was armed with one 20 mm M61A1 Vulcan rotary cannon and 1,028 rounds of ammunition. It has an internal bomb bay and can carry bombs, missiles or fuel tanks on under wing and centerline hardpoints. The maximum bomb load consisted of 16 750-pound (340 kilogram) bombs. For tactical nuclear strikes, the F-105D could carry one B57 or three B61 nuclear bombs.

The F-105 Thunderchief was a supersonic tactical fighter bomber rather than an air superiority fighter. Still, during the Vietnam War, F-105s shot down 27 enemy MiG fighters. 24 of those were shot down with the Thunderchief’s Vulcan cannon.

Republic Aviation Corporation built 833 F-105 Thunderchief fighter bombers at its Farmingdale, New York factory. 610 of those were single-seat F-105Ds. Of the 833 F-105s, 395 were lost during the Vietnam War. 334 were shot down, mostly by antiaircraft guns or missiles, and 17 by enemy fighters. Another 61 were lost due to accidents. The 40% combat loss is indicative of the extreme danger of the missions these airplanes were engaged in.

62-4284 is the only F-105 Thunderchief officially credited with shooting down three enemy fighters during the Vietnam War. Flown by Captain Gene I. Basel, also of the 354th Tactical Fighter Squadron, 62-4284 was “Bison 02” on an attack against the Canal de Rapides Bridge, 27 October 1967. Captain Basel shot down a MiG-17 with the Thunderchief’s 20 mm cannon. The VPAF pilot ejected.

Having survived the Vietnam War, 62-4284 crashed during a peacetime training mission, 4 miles south west of Clayton, Oklahoma, 12 March 1976. The pilot, Captain Larry L. Kline, 465th Tactical Fighter Squadron, Hill Air Force Base, Utah, was killed.

Major John R. Pardo distinguished himself by gallantry in connection with military operations against an opposing armed force over North Vietnam on 10 March 1967. On that date, Major Pardo was flying as the pilot of the lead element on the return from a 1,000 mile flight in which heavy flak damage was encountered. He noticed that his wingman’s aircraft was in trouble and was advised that the aircraft was extremely low on fuel. Realizing that the wingman’s aircraft would not make it out of North Vietnam, Major Pardo implemented maneuvers to literally push the aircraft across the border. The attempt was successful and consequently allowed the crew to avoid becoming prisoners of war. By his gallantry and devotion to duty, Major Pardo has reflected great credit upon himself and the United States Air Force.

The President of the United States of America, in the name of Congress, takes pleasure in presenting the Medal of Honor to Major Merlyn Hans Dethlefsen, United States Air Force, for conspicuous gallantry and intrepidity at the risk of his life above and beyond the call of duty while serving with the 354th Tactical Fighter Squadron, 355th Tactical Fighter Wing, near Thai Nguyen, North Vietnam, on 10 March 1967. Major Dethlefsen was one of a flight of F-105 aircraft engaged in a fire suppression mission designed to destroy a key anti-aircraft defensive complex containing surface-to-air missiles (SAM), an exceptionally heavy concentration of anti-aircraft artillery, and other automatic weapons. The defensive network was situated to dominate the approach and provide protection to an important North Vietnam industrial center that was scheduled to be attacked by fighter bombers immediately after the strike by Major Dethlefsen’s flight. In the initial attack on the defensive complex the lead aircraft was crippled, and Major Dethlefsen’s aircraft was extensively damaged by the intense enemy fire. Realizing that the success of the impending fighter bomber attack on the center now depended on his ability to effectively suppress the defensive fire, Major Dethlefsen ignored the enemy’s overwhelming firepower and the damage to his aircraft and pressed his attack. Despite a continuing hail of anti-aircraft fire, deadly surface-to-air missiles, and counterattacks by MIG interceptors, Major Dethlefsen flew repeated close range strikes to silence the enemy defensive positions with bombs and cannon fire. His action in rendering ineffective the defensive SAM and anti-aircraft artillery sites enabled the ensuing fighter bombers to strike successfully the important industrial target without loss or damage to their aircraft, thereby appreciably reducing the enemy’s ability to provide essential war material. Major Dethlefsen’s consummate skill and selfless dedication to this significant mission were in keeping with the highest traditions of the U.S. Air Force and reflect great credit upon himself and the Armed Forces of his country.

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 Kevin A. Gilroy (AFSN: 0-3109656), United States Air Force, for extraordinary heroism while serving as Electronics Warfare Officer of an F-105 aircraft of the with the 354th Tactical Fighter Squadron, 355th Tactical Fighter Wing, Takhli Royal Thai Air Base, engaged in a pre-strike, missile suppression mission against the Thai Nguyen Steel Works in North Vietnam on 10 March 1967. On that date, Captain Gilroy guided his pilot in attacking and destroying a surface-to-air missile installation protecting one of the most important industrial complexes in North Vietnam. He accomplished this feat even after formidable hostile defenses had destroyed the lead aircraft and had crippled a second. Though his own aircraft suffered extensive battle damage and was under constant attack by MiG interceptors, anti-aircraft artillery, automatic weapons, and small arms fire, Captain Gilroy aligned several ingenious close range attacks on the hostile defenses at great risk to his own life. Due to his technical skill, the attacks were successful and the strike force was able to bomb the target without loss. Through his extraordinary heroism, superb airmanship and aggressiveness, Captain Gilroy has reflected the highest credit upon himself and the United States Air Force.

The President of the United States of America, authorized by Act of Congress, July 8, 1918 (amended by act of July 25, 1963), takes pleasure in presenting the Silver Star to Major Kenneth Holmes Bell (AFSN: FR-25966), United States Air Force, for gallantry in connection with military operations against an opposing armed force while serving as Pilot of an F-105 Thunderchief of the 355th Tactical Fighter Wing, Takhli Royal Thai Air Base, Thailand, PACIFIC Air Forces, in Southeast Asia on 10 March 1967. On that date, Major Bell was a member of a surface-to-air missile suppression flight in support of a strike against a large industrial complex. Major Bell and his flight, with great courage, flew through anti-aircraft defenses which were so dense that the flight leader was downed, and all three of the remaining flight members’ aircraft were damaged. Major Bell’s aircraft was damaged to the extent that aircraft control was marginal. However, he elected to remain in the target area flying through the hail of flak three more times until he had the key missile installation shattered and burning from a series of vicious attacks. Throughout the entire flight, Major Bell exhibited complete disregard for his personal welfare in the face of overwhelming odds. By his gallantry and devotion to duty, Major Bell has reflected great credit upon himself and the United States Air Force.

The F-105 was the largest single-seat, single-engine combat aircraft in history. It was designed as a Mach 2+ tactical nuclear strike aircraft and fighter-bomber. The fuselage of the F-105B incorporated the “area rule” which gave the Thunderchief its characteristic “wasp waist” shape. The F-105F was a two-place variant, flown by a pilot and a weapons system operator. Its high speed, low radar cross-section, and heavy bomb load capacity made it a good candidate for the “Wild Weasel” mission: locating and attacking enemy radar and surface-to-air missile installations.

The F-105F/G Thunderchief was 67 feet (20.422 meters) long with a wingspan of 34 feet, 11 inches (10.643 meters) and overall height of 20 feet, 2 inches (6.147 meters). Its wings were swept 45° at 25% chord. The angle of incidence was 0° and there was no twist. The wings had 3° 30′ anhedral. The total wing area was 385 square feet (35.8 square meters). Modified to the Wild Weasel III configuration, it had an empty weight of 31,279 pounds (14,188 kilograms), and a maximum takeoff weight of 54,580 pounds (24,757 kilograms).

The F-105G Wild Weasel III had a cruising speed of 514 knots (592 miles per hour/952 kilometers per hour). Its maximum speed was 681 knots at Sea Level—0.78 Mach—and 723 knots (832 miles per hour/1,339 kilometers per hour) at 36,000 feet (10,973 meters)—Mach 1.23. It could climb to 30,000 feet (9,144 meters) in 28.0 minutes. The F-105G’s combat ceiling was 43,900 feet (13,381 meters), and it had a combat radius of 391 nautical miles (450 statute miles/724 kilometers). The maximum ferry range, with external fuel tanks, was 1,623 nautical miles (1,868 statute miles/3,006 kilometers).

The Wild Weasel III was armed with one M61A1 Vulcan 20 mm six-barrel rotary cannon with 581 rounds of ammunition, one AGM-78 Standard High-Speed Anti-Radiation Missile (HARM), and two AGM-45A Shrike anti-radiation missiles.

65 F-105Fs were converted to the F-105G Wild Weasel III configuration. Republic Aviation Corporation built 833 F-105 Thunderchief fighter bombers at its Farmingdale, New York, factory. 395 were lost during the Vietnam War. 334 were shot down, mostly by antiaircraft guns or missiles, and 17 by enemy fighters. Another 61 were lost due to accidents. The 40% combat loss is indicative of the extreme danger of the missions these airplanes were engaged in.
