3 April 1926: Virgil Ivan Grissom was born at Mitchell, Indiana, the second of five children of Dennis David Grissom, an electrician, and Cecile King Grissom. “Gus” Grissom attended Mitchell High School, graduating in 1944. He was a member of the Hi-Y Club, the Camera Club, and the Signal Club.
Upon graduation from high school. Virgil I. Grissom enlisted as an aviation cadet in the Air Corps, United States Army, at Fort Benjamin Harrison, Lawrence, Indiana, 9 August 1944. He was assigned to basic flight training at Sheppard Field, Texas, but the War came to an end before he could graduate as a pilot. Then reassigned as a clerk, he requested to be discharged from the Air Corps, which he was in November 1945.
Grissom married Miss Betty Lavonne Moore at Mitchell, Indiana, 6 July 1945. They wood have two sons, Scott and Mark. (In Korea, Grissom named his F-86 Scotty after his first son.)
After the war, Grissom enrolled at Purdue University, Lafayette, Indiana, and in 1950, graduated with the degree of Bachelor of Science in Mechanical Engineering.
He then re-joined the U.S. Air Force in 1950 and was trained at Randolph Air Force Base, Texas, and Williams Air Base, Arizona, where he specialized as a fighter pilot. He was commissioned as a second lieutenant, U.S. Air Force, in March 1952.
Lieutenant Grissom was assigned to he 334th Fighter Interceptor Squadron, 4th Fighter Interceptor Wing, based at Kenpo Air Base (K-14), in the Republic of South Korea. He flew 100 combat missions in the North American Aviation F-86 Sabre. Grissom was promoted to first lieutenant, 11 March 1952. he requested to fly another 25 combat missions, but that was declined and he returned to the United States. Lieutenant Grissom was then assigned as a flight instructor at Bryan Air Force Base, Texas.
Grissom attended a one year program at the Air Force Institute of Technology at Wright-Patterson Air Force Base, Dayton, Ohio, and earned a second bachelor’s degree in aircraft engineering. He was then sent to the Air Force Test Pilot School at Edwards Air Force Base, California (Class 56D). After completion, he was assigned as a fighter test pilot back at Wright-Patterson.
One of 508 pilots who were considered by NASA for Project Mercury, Gus Grissom was in the group of 110 that were asked to attend secret meetings for further evaluation. From that group, 32 went on with the selection process and finally 18 were recommended for the program. Grissom was one of the seven selected.

Major Grissom was the second American to “ride the rocket” aboard Mercury-Redstone 4. He named his space capsule Liberty Bell 7. The spacecraft reached a maximum altitude of 102.8 nautical miles (118.3 statute miles, 190.4 kilometers) and traveled 262.5 nautical miles (302.1 statute miles, 486.2 kilometers) down range. During the 15 minute, 37 second, flight, Grissom was weightless for 5:00 minutes.
Next he orbited Earth as commander of Gemini III along with fellow astronaut John Young. He was back-up commander for Gemini VI-A, then went on to the Apollo Program.

Gus Grissom was selected as the commander for Apollo I in January 1968. This was to be the first manned flight of the Apollo spacecraft. Ed White and Roger Chaffee were the other members of the flight crew.
As commander of AS-204 (Apollo I), LCOL Virgil I. Grissom, USAF was killed along with Ed White and Roger Chafee during a test on the launchpad, 27 January 1967.

Gus Grissom was an Air Force Command Astronaut with over 4,600 hours flight time. He was the first American astronaut to fly into space twice, and logged 5 hours, 7 minutes of space flight. For his military service, Grissom was awarded the Distinguished Flying Cross; the Air Medal with one bronze oak leaf cluster (two awards); the American Campaign medal; the World War II Victory Medal; teh Korean Service Medal; the United Nations Korea medal, and the Korean War Service Medal of the Republic of South Korea. For his NASA service, he was awarded the Congressional Space Medal of Honor (posthumous); the NASA Distinguished Service Medal (two awards); and the NASA Exceptional Service Medal.
Had he lived, it is very possible that Grissom would have commanded the first Apollo mission to land on The Moon.
The remains of Lieutenant Colonel Virgil Ivan Grissom, United States Air Force, NASA Astronaut, are buried at the Arlington National Cemetery, Arlington, Virginia.
B-25 Mitchell bombers aboard USS Hornet (CV-8), with USS Gwin (DD-433) and USS Nashville (CL-43), somewhere in the Pacific, April 1942. (U.S. Navy)
2 April 1942: After loading sixteen North American Aviation B-25B Mitchell medium bombers and their crews of the 17th Bombardment Group (Medium) at NAS Alameda, the recently commissioned United States Navy aircraft carrier USS Hornet (CV-8) departed San Francisco Bay with her escorts and headed for a secret rendezvous with Vice Admiral William F. Halsey, Jr., and Task Force 16.
The new carrier was under command of Captain Marc A. Mitscher. The strike group was commanded by Lieutenant Colonel James H. (“Jimmy”) Doolittle, U.S. Army Air Corps. Until the second day at sea, only six U.S. military officers knew of the mission.
The photograph above shows some of the bombers secured on Hornet‘s flight deck. An escorting destroyer, USS Gwin (DD-433) is closing from astern, with light cruiser USS Nashville (CL-43) in the distance. Two more ships are on the horizon.

USS Hornet was a brand new Yorktown-class aircraft carrier, commissioned 20 October 1941. It had just completed its shakedown cruise in the Atlantic when it was sent west for this mission.
The ship was 824 feet, 9 inches (251.384 meters) long, overall, with a maximum width of 114 feet (34.747 meters). Hornet‘s dimensions at the waterline (full load displacement) were 761 feet (232 meters) long with a beam of 83 feet, 3 inches (25.375 meters). Its draft was 28 feet (8.5 meters).
The flight deck had two hydraulic catapults, and three elevators for bringing aircraft up from the hangar deck. A third catapult was on the hangar deck, launching aircraft laterally.
Powered by four geared steam turbines driving four propeller shafts, Hornet‘s engines produced 120,000 shaft horsepower. The carrier’s maximum speed was 33.84 knots (39.94 miles per hour/62.67 kilometers per hour), and maximum range, 12,500 nautical miles (14,385 kilometers).

Higgins, U.S.N., commanding, closes on the carrier’s right rear quarter. The sixteen Army bombers used all the space available on Hornet’s flight deck.(U.S. Navy)
The aircraft carrier’s primary armament was its air wing, consisting of a squadron each of Grumman F4F Wildcat fighters, Douglas SBD Dauntless dive bombers and Douglas TBD Devastator torpedo bombers. For the Halsey-Doolittle Raid, Hornet‘s air wing was stored on the hangar deck and unavailable.
“To make room for the Army bombers, Hornet had struck her own planes below. Wildcats and Devastators, with wings folded, and dismantled SBDs were packed into every available space, even hung from the overhead. So, except for her few guns, the carrier was defenseless until she rendezvoused with Task Force 16. . . .”
—History of United States Naval Operations in World War II, Volume III, The Rising Sun in the Pacific, by Samuel Eliot Morison, Little, Brown & Company, Boston, 1988, Chapter XX at Page 392.
For defense, the ship was lightly armored, with 2.5–4 inches (6.35–10.2 centimeters) of belt and deck armor. She also carried eight 5-inch, 38-caliber (5″/38) dual-purpose guns in single mounts, thirty 20mm Oerlikon autocannon, twenty water-cooled 1.1-inch, 75-caliber (1.1″/75) guns in four-gun mounts, and twenty-four Browning .50-caliber (12.7 millimeter) machine guns.
Including the ship’s air wing, the complement was 2,919 men.
USS Hornet fought at the Battle of Midway, June 3–7, 1942. She was sunk at the Battle of the Santa Cruz Islands, 26 October 1942, having been hit by two airplanes, 8 bombs, 16 torpedoes and an unknown number of 5-inch shells.¹

Messerschmitt Me 262 A-1 WNr. 111711 (U.S. Air Force)
31 March 1945: Messerschmitt Aktiengesellschaft test pilot and technical inspector Hans Fay (1888–1959) defected to the Allies at Frankfurt/Rhein-Main Airfield, Frankfurt, Germany.
He brought with him a brand-new Messerschmitt Me 262 A-1 twin-engine jet fighter.
Fay had been waiting for an opportunity to bring an Me 262 to the Americans, but feared reprisals against his parents. When he learned that the U.S. Army controlled their town, he felt that it was safe to go ahead with his plan.
On 31 March, Fay was ordered to fly one of twenty-two new fighters from the Me 262 assembly factory at Schwäbisch-Hall to a safer location at Neuburg an der Donau, as they were in danger of being captured by advancing Allied forces. His airplane was unpainted other than low visibility Balkenkreuz markings on the wings and fuselage, and standard Luftwaffe markings on the vertical fin. Fay was the fourth to take off, but instead of heading east-southeast toward Neuburg, he flew north-northwest to Frankfurt, arriving there at 1:45 p.m.

The Messerchmitt Me 262 Schwalbe was the first production jet fighter. It was a single-place, twin-engine airplane with the engines placed in nacelles under the wings. It was 10.6 meters (34 feet, 9.3 inches) long with a wingspan of 12.51 meters (41 feet, 5.2 inches) and overall height of 3.85 meters (12 feet, 7.6 inches). According to Fay, the fighter’s empty weight was 3,760 kilograms (8,289 pounds) and the maximum gross weight was 7,100 kilograms (15,653 pounds) at engine start.¹
The Me-262 wings had 6° dihedral. The leading edges were swept aft to 20°, while the trailing edges of the inner panels swept forward 8½° to the engine nacelle, then outboard of the engines, aft 5°. The purpose of the sweep was to keep the airplane’s aerodynamic center close to the center of gravity, a technique first applied to the Douglas DC-2. The total wing area was 21.7 square meters (233.6 square feet).

The Me 262 A-1 was powered by two Junkers Jumo TL 109.004 B-1 turbojet engines. The 004 was an axial-flow turbojet with an 8-stage compressor section, six combustion chambers, and single-stage turbine. The 004 engine case was made of magnesium for light weight, but this made it vulnerable to engine fires. The engine was designed to run on diesel fuel, but could also burn gasoline or, more commonly, a synthetic fuel produced from coal, called J2. The engine was first run in 1940, but was not ready for production until 1944. An estimated 8,000 engines were built. The 004 B-1 idled at 3,800 r.p.m., and produced 1,984 pounds of thrust (8.825 kilonewtons) at 8,700 r.p.m. The engine was 2 feet, 10 inches (0.864 meters) in diameter, 12 feet, 8 inches (3.861 meters) long, and weighed 1,669 pounds (757 kilograms).
24 March 1946: The Jumo 004 was tested at the NACA Aircraft Engine Research Laboratory, Cleveland, Ohio. The axial-flow compressor section is visible. (NASA)
During interrogation, Hans Fay said that for acceptance, the production Me 262 was required to maintain a minimum of 830 kilometers per hour (515 miles per hour) in level flight, and 950 kilometers per hour (590 miles per hour) in a 30° dive. The fighter’s cruise speed was 750 kilometers per hour (466 miles per hour).
A number of factors influenced the Me 262’s maximum range, but Fay estimated that the maximum endurance was 1 hour, 30 minutes. U.S. Air Force testing establish the range as 650 miles (1,046 kilometers) and service ceiling at 38,000 feet (11,582 meters).
Lt. Walter J. McAuley, Jr.
The Me 262 A-1 was armed with four Rheinmetall-Borsig MK 108 30 mm autocannons with a total of 360 rounds of ammunition. (The Me 262 A-2 had just two autocannons with 160 rounds.) It could also be armed with twenty-four R4M Orkan 55 mm air-to-air rockets. Two bomb racks under the fuselage could each be loaded with a 500 kilogram (1,102 pounds) bomb.
1,430 Me 262s were produced. They entered service during the summer of 1944. Luftwaffe pilots claimed 542 Allied airplanes shot down with the Me 262.
Hans Fay’s Messerschmitt Me 262 A-1, WNr. 111711, was transported to the United States and was tested at Wright Field, Dayton, Ohio.
711 was lost during a test flight, 20 August 1946, when one of its engines caught fire. The test pilot, Lieutenant Walter J. “Mac” McAuley, Jr., U.S. Army Air Corps, safely bailed out. The Me 262 crashed 2 miles (3.2 kilometers) east of Lumberton, Ohio, and was completely destroyed.

Walter J. McAuley, Jr.,² was born 10 March 1917 at Fort Worth, Texas. He was the fourth child of Walter J. McAuley and Lola Mahaffey McAuley. Walter attended Texas A&M College at College Station, Texas. While there, he also worked as a mechanic. He graduated with a bachelor of science degree in 1941.
McAuley had brown hair, blue eyes, was 5 feet, 9 inches (1.75 meters) tall and weighed 160 pounds (75.6 kilograms).
McAuley enlisted as a seaman, second class, United States Naval Reserve, and served from 11 April to 3 December 1941. He transferred to the U.S. Army as a private, Air Corps Enlisted Reserve Corps (A.C.E.R.C.), 2 May 1942. Private McAuley was accepted as an aviation cadet, Air Corps, 18 October 1942.
Aviation Cadet McAuley was commissioned as a second lieutenant, Army of the United States (A.U.S.), 29 July 1943, and placed on active duty. He was promoted to first lieutenant, A.U.S., one year later, 1 August 1944.
Lieutenant McAuley was promoted to captain, Air-Reserve, 30 July 1947. On 10 July 1947, he received a permanent commission as a first lieutenant, Air Corps, United States Army. His date of rank was retroactive to 10 March 1945.
After the establishment of the United States Air Force, Lieutenant McAuley was transferred to the new service. He was number 6,626 on the register of Air Force first lieutenants.
McCauley rose to the rank of lieutenant colonel in the U.S. Air Force. He was released from duty 31 December 1962.
Walter J. McAuley Jr., married Miss Mary Elizabeth Sloss, 8 May 1943. They divorced 25 March 1969. He then married Lillian R. Zwickl, 3 April 1969. They also divorced, 10 September 1971.
Lieutenant Colonel McAuley died 11 March 1985. He was buried at Greenwood Memorial Park, Fort Worth, Texas.

North American Aviation B-25B Mitchell 40-2291 at Eglin Field, Florida, March 1942. (U.S. Air Force)
27 March 1942: After three weeks of intensive training at Eglin Field, Florida, twenty-two North American Aviation B-25B Mitchell twin-engine medium bombers of the 34th Bombardment Squadron (Medium), 17th Bombardment Group (Medium), U.S. Army Air Force, under the command of Lieutenant Colonel James Harold Doolittle, completed a two-day, low-level, transcontinental flight, and arrived at the Sacramento Air Depot, McClellan Field, California, for final modifications, repairs and maintenance before an upcoming secret mission: The Halsey-Doolittle Raid.
The B-25 had made its first flight 19 October 1940 with test pilot Vance Breese and engineer Roy Ferren in the cockpit. It was a mid-wing airplane with twin vertical tails and retractable tricycle landing gear. The first 8–10 production airplanes were built with a constant dihedral wing. Testing at Wright Field showed that the airplane had a slight tendency to “Dutch roll” so all B-25s after those were built with a “cranked” wing, using dihedral for the inner wing and anhedral in the wing outboard of the engines. This gave it the bomber’s characteristic “gull wing” appearance. The two vertical stabilizers were also increased in size.

The B-25B Mitchell was operated by a crew of five: two pilots, a navigator, bombardier and radio operator/gunner. It was 53 feet, 0 inch (16.154 meters) long with a wingspan of 67 feet, 7.7 inches (20.617 meters) and overall height of 15 feet, 9 inches (4.801 meters). The The B-25B had an empty weight of 20,000 pounds (9,072 kilograms) and the maximum gross weight was 28,460 pounds (12,909 kilograms).
The B-25B was powered by two air-cooled, supercharged, 2,603.737-cubic-inch-displacement (42.668 liter) Wright Aeronautical Division Cyclone 14 GR2600B665 (R-2600-9) two-row 14-cylinder radial engines with a compression ratio of 6.9:1. The engines had a Normal Power rating of 1,500 horsepower at 2,400 r.p.m., and 1,700 horsepower at 2,600 r.p.m. for takeoff, burning 100-octane gasoline. These engines (also commonly called “Twin Cyclone”) drove three-bladed Hamilton Standard Hydromatic variable-pitch propellers through 16:9 gear reduction. The R-2600-9 was 5 feet, 3.1 inches (1.603 meters) long and 4 feet, 6.26 inches (1.378 meters) in diameter. It weighed 1,980 pounds (898 kilograms).

The medium bomber had a maximum speed of 322 miles per hour (518 kilometers per hour) at 15,000 feet (4,572 meters) and a service ceiling of 30,000 feet (9,144 meters).
It could carry a 3,000 pound (1,361 kilograms) bomb load 2,000 miles (3,219 kilometers). Defensive armament consisted of a single Browning M2 .30-caliber machine gun mounted in the nose, two Browning M2 .50-caliber machine guns in a power dorsal turret, and two more .50s in a retractable ventral turret. (The lower turrets were removed from all of the Doolittle B-25s.)
