3 November 1950: Air India Flight 245, a Lockheed L-749A Constellation, VT-CQP, Malabar Princess, was on a flight from Bombay, India, to London, England, with intermediate stops at Cairo, Egypt and Geneva, Switzerland. The aircraft was under the command of Captain Alan R. Saint, with co-pilot Vijay Yeshwant Korgaokar, three navigators and a radio operator.
At 9:43 a.m., Malabar Princess crashed into the Rochers de la Tournette (Tournette Spur) on the west side of Mont Blanc at an approximate elevation of 15,344 feet (4,677 meters). All 48 persons on board were killed.
Air India International was the national airline of India, having been formed from Tata Airlines. On 8 June 1948, Air India’s first scheduled flight departed Bombay for Cairo, Geneva and London. The airliner was Malabar Princess.
On 24 January 1966, Air India Flight 101, a Boeing 707-437, VT-DMN, named Kanchenjunga,¹ crashed at almost the same location on Mount Blanc. All 117 persons on board were killed.
The Lockheed L-749A Constellation was operated by a flight crew of four, with two to four flight attendants. It could carry up to 81 passengers. The airplane was 97 feet, 4 inches (29.667 meters) long with a wingspan of 123 feet (37.490 meters) and an overall height of 22 feet, 5 inches (6.833 meters). It had an empty weight of 56,590 pounds (25,669 kilograms) and maximum takeoff weight of 107,000 pounds (48,534 kilograms).
The L-749A was powered by four air-cooled, supercharged and fuel-injected 3,347.66-cubic-inch-displacement (54.858 liter) Wright Aeronautical Division Cyclone 18 (also known as the Duplex-Cyclone) 749C18BD1 two-row 18-cylinder radial engines with a compression ratio of 6.5:1. They had a Normal Power rating of 2,100 horsepower at 2,400 r.p.m., and Takeoff Power rating 2,500 horsepower at 2,800 r.p.m. (five minute limit). The engines drove three-bladed Curtiss-Electric propellers through a 0.4375:1 gear reduction. This engine featured “jet stacks” which converted the piston engines’ exhaust to usable jet thrust, adding about 15 miles per hour (24 kilometers per hour) to the airplane’s speed. The 749C18BD1 was 6 feet, 6.52 inches (1.994 meters) long, 4 feet, 7.62 inches (1.413 meters) in diameter, and weighed 2,915 pounds (1,322 kilograms).
The L-749 had a cruise speed of 345 miles per hour (555 kilometers per hour) and a range of 4,995 miles (8,039 kilometers). Its service ceiling was 24,100 feet (7,346 meters).
The Air India Flight 245 crash was the basis for a novel, La neige en deuil (“The Snow in Mourning”), written by Henri Troyat (née Lev Aslanovic Tarassov), which in turn inspired the 1956 Edward Dymtryk motion picture, “The Mountain.” The film starred Spencer Tracy, Robert Wagner and Anna Kashfi.² Tracy was nominated by the British Academy of Film and Television Arts for an award for his performance.
¹ Kanchenjunga is the name of the world’s third highest mountain, an “eight thousander” located 125 kilometers (78 miles) east-southeast of Mount Everest in the Himalayas. Its summit is 8,598 meters (28,209 feet) above Sea Level. It is considered to be a sacred mountain. Climbers are not allowed there.
² Anna Kashfi (née Joan O’Callaghan) was the first Mrs. Marlon Brando.
5 October 1954: Chief Engineering Test Pilot Tony LeVier made the first flight in the second prototype Lockheed XF-104 Starfighter, 53-7787, at Edwards Air Force Base in the high desert of southern California. This was the armament test aircraft and was equipped with a General Electric T171 Vulcan 20mm Gatling gun. This six-barreled gun was capable of firing at a rate of 6,000 rounds per minute.
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).
While the first prototype, 53-7776, was equipped with a Buick J65-B-3 turbojet engine, the second used a Wright Aeronautical Division J65-W-6 with afterburner. Both were improved derivatives of the Armstrong Siddely Sa.6 Sapphire, built under license. The J65 was a single-shaft axial-flow turbojet with a 13-stage compressor and 2-stage turbine. The J65-B-3 was rated at 7,330 pounds of thrust, and the J65-W-6, rated at 7,800 pounds (34.70 kilonewtons), and 10,500 pounds (46.71 kilonewtons) with afterburner.
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).
53-7787 was lost 19 April 1955 when it suffered explosive decompression at 47,000 feet (14,326 meters) during a test of the T171 Vulcan gun system. The lower escape hatch had come loose due to an inadequate latching mechanism. Lockheed test pilot Herman R. (“Fish”) Salmon was unable to find a suitable landing area and ejected at 250 knots (288 miles per hour/463 kilometers per hour) and 15,000 feet (4,572 meters). The XF-104 crashed 72 miles (117 kilometers) east-northeast of Edwards Air Force Base. Salmon was found two hours later, uninjured, about 2 miles (3.2 kilometers) from the crash site.
The YF-104A pre-production aircraft and subsequent F-104A production aircraft had many improvements over the two XF-104 prototypes. The fuselage was lengthened 5 feet, 6 inches (1.68 meters). The J65 engine was replaced with a more powerful General Electric J79-GE-3 turbojet. There were fixed inlet cones added to control airflow into the engines. A ventral fin was added to improve stability.
21 September 1942: At Boeing Field, Seattle, Washington, the Boeing Model 345, the first of three XB-29 prototypes, Air Corps serial number 41-002, took off on its first flight.
Edmund T. “Eddie” Allen, Director of Aerodynamics and Flight Research, was in command, with Al Reed, Chief of Flight Test and Chief Test Pilot, as co-pilot. They climbed to 6,000 feet (1,829 meters) and began testing the XB-29’s stability and control, control power and response, and stall characteristics.
The flight was uneventful. Landing after 1 hour, 15 minutes, Allen is supposed to have said, “She flew!”
The XB-29 was 98 feet, 2 inches (29.921 meters) long with a wing span of 141 feet, 3 inches (43.053 meters), and 27 feet, 9 inches (8.458 meters) high to the top of its vertical fin. The prototype bomber had a gross weight of 105,000 pounds (47,627 kilograms).
The prototype bomber was powered by four air-cooled, supercharged and fuel-injected 3,347.662-cubic-inch-displacement (54.858 liter) Wright Aeronautical Division Duplex-Cyclone 670C18H1 (R-3350-13) twin-row 18-cylinder radial engines with a compression ratio of 6.85:1. The R-3350-13 was rated at 2,000 horsepower at 2,400 r.p.m., and 2,200 horsepower at 2,800 r.p.m. for takeoff, burning 100-octane gasoline. These engines drove 17-foot-diameter (5.182 meters) three-bladed Hamilton Standard constant-speed propellers through a gear reduction of 0.35:1. The R-3350-13 was 76.26 inches (1.937 meters) long, 55.78 inches (1.417 meters) in diameter, and weighed 2,668 pounds (1,210 kilograms). Wright built 50 of these engines.
The XB-29 had a maximum speed of 368 miles per hour (592 kilometers per hour) and cruised at 255 miles per hour (410 kilometers per hour). Its service ceiling was 32,100 feet (9,784 meters).
The airplane was designed to carry 20,000 pounds (9,072 kilograms) of bombs. Though the prototypes were unarmed, the production B-29s were defended by 10 Browning AN-M2 .50-caliber machine guns in four remotely-operated power turrets, with 2 more .50-caliber machine guns and a single AN-M2 20mm autocannon in the tail.
The B-29 Superfortress was the most technologically advanced—and complex—aircraft of the War. It required the manufacturing capabilities of the entire nation to produce. Over 1,400,000 engineering man-hours had been required to design the prototypes.
The B-29 was manufactured by Boeing at Seattle and Renton, Washington, and at Wichita, Kansas; by the Glenn L. Martin Company at Omaha, Nebraska; and by Bell Aircraft Corporation, Marietta, Georgia. There were three XB-29 prototypes, 14 YB-29 pre-production test aircraft, 2,513 B-29, 1,119 B-29A, and 311 B-29B Superfortress aircraft. The bomber served during World War II and the Korean War and continued in active U.S. service until 1960.
The first prototype, 41-002, was scrapped in 1948.
2 September 1944: Lieutenant (Junior Grade) George Herbert Walker Bush, United States Naval Reserve, led a flight of four TBF/TBM Avenger torpedo bombers of Torpedo Squadron 51 (VT-51), from the Independence-class light aircraft carrier USS San Jacinto (CVL-30), against a radio transmission station on the island of Chichi-Jima.
The Avenger had a crew of three. Along with Lt (j.g.) Bush were Lt. (j.g.) William G. White, USNR, gunner, and radio operator ARM 2/c John Lawson Delaney, USNR.
Each airplane was armed with four 500-pound¹ general purpose bombs. The flight was joined by eight Curtiss-Wright SB2C Helldiver dive bombers of VB-20, escorted by twelve Grumman F6F-5 Hellcat fighters of VF-20, from USS Enterprise (CV-6).
Chichi-Jima is the largest island in the Ogasawara Archipelago of the Bonin Islands, approximately 150 miles (240 kilometers) north of Iwo Jima and 620 miles (1,000 kilometers) south of Tokyo, Japan. The United States Hydrographic Survey described the island in 1920 as “very irregular in shape,” approximately 4¼ miles (7.2 kilometers) long and 2 miles (3.2 kilometers) wide. The area of the island is presently given as 23.45 square kilometers (9.05 square miles). Its highest point is 326 meters (1,070 feet) above Sea level. The island has a small sea port where midget submarines were based beginning in August 1944. Chichi-Jima was heavily garrisoned with 20,656 Imperial Japanese Army and Navy personnel, and 2,285 civilian workers.²
Lieutenant Bush’s flight was scheduled for a time over target of 0825–0830. They encountered heavy antiaircraft fire and Bush’s Avenger was hit. With the torpedo bomber on fire, Bush continued the attack and later reported good results. Unable to return to the aircraft carrier, he flew away from the island to limit the risk of capture of the crew by the enemy when they bailed out.
Bush and one other crewman (which one is not known) bailed out. While Bush parachuted safely, the second crewman’s parachute never opened. The third crewman went down with the airplane. Both Lieutenant White and Radioman Delaney were killed.
The Gato-class fleet submarine USS Finback (SS-230) was stationed near the island on lifeguard duty during the attack. At 0933, Finback was notified of an aircraft down nine miles northeast of Minami-Jima. Escorted by two F6F fighters, the submarine headed for the location. At 1156, Finback picked up Lt. Bush, floating in his life raft. A search for White and Delaney was unsuccessful. Their bodies were not recovered.
(Later that same day, Finback, while submerged, towed a second pilot and his life raft away from Magane-Iwa, as he held on to the sub’s periscope.)
Lieutenant Bush and the other rescued pilots remained aboard for the remainder of Finback‘s war patrol (her tenth), and were then returned to Pearl Harbor. In November he rejoined San Jacinto for operations in the Philippines.
George Herbert Walker Bush was born at Milton, Massachusetts, 12 June 1924, the son of Prescott Sheldon Bush and Dorothy Walker Bush. He attended high school at the Phillips Academy in Andover, Massachusetts.
One day after his 18th birthday, 13 June 1942, Bush enlisted as a seaman, 2nd class, in the United States Naval Reserve. He was appointed an aviation cadet and underwent preflight training at the University of North Carolina, Chapel Hill. He was honorably discharged 8 June, and commissioned as an ensign, United States Naval Reserve, 9 June 1943. At the age of 19 years, 2 days, he became the youngest Naval Aviator in history. (His age record was broken the following month by Ensign Charles Stanley Downey, who was commissioned 16 July 1943 at the age of 18 years, 11 months, 14 days.)
Ensign Bush continued flight training at NAS Pensacola, Florida, and then the Carrier Qualification Training Unit, NAS Glenville, Illinois. After training with the Atlantic Fleet, Ensign Bush was assigned to Torpedo Squadron Fifty-One (VT-51), in September 1943. He was promoted to lieutenant (junior grade), 1 August 1944.
After leaving San Jacinto, Bush was assigned to NAS Norfolk, Virginia, from December 1944 to February 1945. He then joined Torpedo Squadron Ninety-Seven (VT-97) and then VT-153.
Lieutenant (j.g.) Bush was released from active duty on 18 September 1945, retaining his commission. He was promoted to lieutenant 16 November 1948. On 24 October 1955, Lieutenant Bush resigned from the U.S. Navy.
During World War II, George H. W. Bush flew 58 combat missions. He flew a total of 1,221 hours and made 126 carrier landings. He was awarded the Distinguished Flying Cross, the Air Medal with two gold stars (three awards), and the Presidential Unit Citation.
He would later become the forty-first President of the United States of America.
The airplane flown by Lt. (j.g.) Bush on 2 September 1944 was a General Motors TBM-1C Avenger torpedo bomber, Bu. No. 46214. This was a licensed variant of the Grumman TBF-1C Avenger, built by the General Motors Corporation Eastern Aircraft Division at Linden, New Jersey.
The Avenger was designed by Robert Leicester Hall, Chief Engineer and Test Pilot for the Grumman Aircraft Engineering Corporation, Bethpage, New York. The prototype XTBF-1 made its first flight 1 August 1941. It was a large single-engine aircraft, operated by a crew of three (pilot, radio operator and ball turret gunner). It was equipped with folding wings for storage on aircraft carriers. Production of the torpedo bomber began with the opening of a new manufacturing plant, Sunday, 7 December 1941. The first production Avenger was delivered to the U.S. Navy in January 1942.
The TBF-1 and TBM-1 were 40 feet, 11 inches (12.471 meters) long, with a wingspan of 54 feet, 2 inches (16.510 meters) and overall height of 16 feet, 5 inches (5.004 meters). The airplane had an empty weight of 10,545 pounds (478 kilograms), and its maximum gross eight was 17,895 pounds (8,117 kilograms). The Avenger was the largest single-engine aircraft of World War II.
The Avenger was powered by one of several variants of the Wright Aeronautical Division Cyclone 14 (R-2600): GR2600B698 (R-2600-8 and -8A); GR2600B676 (R-2600-10); and 776C14B31. The R-2600 was series of air-cooled, supercharged, 2,603.737-cubic-inch-displacement (42.688 liter), two-row 14-cylinder radial engines. The engines used in the Avengers all had a compression ratio of 6.9:1, supercharger ratios of 7.06:1 and 10.06:1, and propeller gear reduction ratio of 0.5625:1.
The R-2600-8, -8A and -10 had Normal Power ratings of 1,500 horsepower at 2,400 r.p.m. at Sea Level, and 1,700 horsepower at 2,600 r.p.m. for takeoff. The R-2600-20 was rated at 1,600 horsepower at 2,400 r.p.m., and 1,900 horsepower at 2,800 horsepower, respectively.
Dimensions and weights varied. The R-2600-8 and -8A were 64.91 inches (1.649 meters) long. The -10 was 74.91 inches (1.903 meters) long, and the length of the -20 was 66.08 inches (1.678 meter). The R-2600-8 and 8A and -10 were 54.26 inches (1.378 meters) in diameter. The -20 was 54.08 inches (1.374 meters). The -8 and -8A both weighed 1,995 pounds (905 kilograms). The -10 weighed 2,115 pounds (959 kilograms) and the -20 weighed 2,045 pounds (928 kilograms).
The engines drove a three-bladed Hamilton Standard Hydromatic constant-speed propeller.
The TBF/TBM had a cruise speed of 147 miles per hour (237 kilometers per hour) and maximum speed of 276 miles per hour (444 kilometers per hour) at 16,500 feet (5,029 meters). The service ceiling was 30,100 feet (9,174 meters). Its maximum range was 1,010 miles (1,625 kilometers).
The Avenger was armed with one air-cooled Browning AN-M2 .50-caliber machine gun mounted in each wing, firing forward. Another .50-caliber machine gun was installed in an electrically-operated dorsal ball turret. In the ventral position was a Browning M2 .30-caliber aircraft machine gun in a flexible mounting.
The primary weapon of the Avenger was carried in an enclosed weapons bay. It could be armed with one Mk. 13 aerial torpedo, ³ or up to 2,000 pounds (907 kilograms) of bombs.
The Grumman Aircraft Engineering Corporation produced TBF Avengers from Early 1942 until 1943, when production was taken over by the General Motors Corporation Eastern Aircraft Division. Grumman produced 2,290 TBFs, while Eastern built 9,836 TBMs.
Lieutenant Bush’s aircraft carrier, USS San Jacinto (CVL-30), was an Independence-class light carrier. It had been started by the New York Shipbuilding Corporation as a Cleveland-class light cruiser, USS Newark (CL-100), but was converted during construction. Construction took 11 months and the ship was launched 26 September 1943. It was commissioned 15 November 1943.
The carrier was 622.5 feet (189.7 meters) long, with a beam of 71.5 feet (21.8 meters) and draft of 26 feet (7.9 meters). It had a full load displacement of 15,100 long tons (16,912 short tons, or 15,342 metric tons). The ship was powered by steam turbines producing 100,000 horsepower and driving four shafts. San Jacinto was capable of a maximum 31.6 knots (36.4 miles per hour, or 58.5 kilometers per hour).
San Jacinto had a complement of 1,549 men, and carried 45 airplanes. For defense, it was armed with 28 Bofors 40 millimeter anti-aircraft guns and 40 Oerlikon 20 millimeter autocannon.
San Jacinto was decommissioned 1 March 1947 and was later scrapped.
On 7 October 2006, the tenth and final Nimitz-class supercarrier was christened USS George H.W. Bush (CVN-77) in honor of President Bush’s service to his country.
¹ The most common U.S. 500-pound general purpose bomb of World War II was the AN-M64. Nominally a 500-pound (227 kilogram) bomb, the munition actually weighed from 516.3 to 535.4 pounds (234.2 to 242.9 kilograms), depending on the explosive used. It contained 266 pounds (120.7 kilograms) of TNT, or 258.5 pounds (117.3 kilograms) of a 50/50 TNT and Amatol mixture. For easy identification, these were marked with a single 1-inch (2.54 centimeter) wide yellow band painted at the nose and tail. Composition B bombs, which were marked with two yellow identification bands, contained 272.7 pounds (123.7 kilograms) of explosive, while the heaviest was filled with 278.3 pounds (126.2 kilograms) of Tritonal. This variant was marked with three yellow bands. The bomb, without fins or fuses, was 36 inches (0.914 meters) long. The overall length was 59.16 inches (1.503 meters), including nose and tail fuses. The maximum diameter was 10.9 inches (0.277 meters).
² Personnel numbers as of 3 September 1945.
³ The U.S. Navy Torpedo, Mark 13, was a gyroscopically-steered single-speed anti-ship torpedo designed to be dropped from aircraft. It was 13 feet, 8.55 inches (4.180 meters) long, 1 foot, 10.42 inches (0.570 meters) in diameter and weighed 1,949 pounds (884 kilograms) ± 20 pounds (9 kilograms). The warhead contained a 400 pound (181 kilogram) TNT explosive charge. The Mk. 13 was driven by a two-stage alcohol-fueled geared steam turbine, turning 10,983 r.p.m., with the coaxial counter-rotating propellers turning 1,150 r.p.m. It was capable of running at 33.5 knots (38.6 miles per hour, or 62.0 kilometers per hour), with a range of 6,300 yards (5.8 kilometers). This same type torpedo was used by the U.S. Navy’s PT boats late in the war.

19 August 1940: At Mines Field (now known as Los Angeles International Airport), the first North American Aviation B-25 twin-engine medium bomber, serial number 40-2165, took off on its first flight with test pilot Vance Breese at the controls and engineer Roy Ferren in the co-pilot’s position.
The airplane, North American model NA-62, serial number 62-2834, was developed from two earlier designs which had been evaluated by the U.S. Air Corps but rejected, and it was ordered into production without a prototype being built.
The first few B-25s built—sources vary, but 8–10 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, with the outer wing panels having very slight dihedral ¹ and giving it the bomber’s characteristic “gull wing” appearance. The two vertical stabilizers were also increased in size.
40-2165 was retained by North American for testing while the next several aircraft were sent to Wright Field.
The B-25 was named Mitchell in honor of early air power advocate Brigadier General Billy Mitchell. A total of 9,984 B-25s, F-10 reconnaissance variants and U.S. Navy and Marine Corps PBJ-1 patrol bombers were built by North American Aviation at Inglewood, California and Kansas City, Kansas. The last one, a TB-25J, remained in service with the U.S. Air Force until 1960.
Twenty-three B-25s were built before the B-25A Mitchell went into production. The B-25 was operated by a crew of five. It was 54 feet, 1 inch (16.485 meters) long with a wingspan of 67 feet, 6.7 inches (20.592 meters) and overall height of 16 feet, 4 inches (4.978 meters). The empty weight was 17,258 pounds (7,828 kilograms) and the maximum gross weight was 28,557 pounds (12,953 kilograms).
The B-25 was powered by two air-cooled, supercharged, 2,603.737-cubic-inch-displacement (42.688 liter) Wright Aeronautical Division Cyclone 14 GR2600B665 (R-2600-9) two-row 14-cylinder radial engines which were rated at 1,500 horsepower at 2,400 r.p.m., and 1,700 horsepower at 2,600 r.p.m. for takeoff. 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 bomb load 2,000 miles (3,219 kilometers).
Defensive armament consisted of three air-cooled Browning M2 .30-caliber aircraft machine guns and one Browning AN-M2 .50-caliber machine gun.
After testing was completed, B-25 40-2165 was retained by North American and modified as a company transport. On 8 January 1945, flown by Edgar A. Stewart, the airplane suffered an engine failure and made a forced landing at Mines Field—the location of its first flight. The prototype B-25 was damaged beyond repair.
¹ The wing center section of the B-25H and B-25J has 4° 38′ 23″ dihedral. The outer sections have 0° 21′ 39″. The wing has 2° 29′ 37″ negative twist.
