7 July 1985: The Strategic Air Command received the first operational Rockwell B-1B Lancer, serial number 83-0065, Star of Abilene, at Dyess Air Force Base, Abilene, Texas. It flew for 17 years, 7 months, 23 days before being retired 1 March 2003 and preserved at Dyess.
The Rockwell B-1B is a long-range, supersonic bomber with variable-sweep wings. It is operated by two pilots and two combat systems officers. The Rockwell B-1B is 146 feet (44.501 meters) long, with the wing span varying from 79 feet (24.079 meters) to 137 feet (41.758 meters). It is 34 feet (10.363 meters) high at the top of the vertical fin. The bomber’s empty weight is 192,000 pounds (87,090 kilograms) and the Maximum Takeoff Weight (MTOW) is 477,000 pounds (216,364 kilograms).
The B-1B is powered by four General Electric F101-GE-102 afterburning turbofan engines. This is an axial-flow engine with a 2-stage fan section, 9-stage compressor and 3-stage turbine (1 high- and 2 low-pressure stages). It is rated at 17,390 pounds of thrust (77.35 kilonewtons), and 30,780 pounds of thrust (136.92 kilonewtons) with afterburner. The F101-GE-102 is 15 feet, 0.7 inches (4.590 meters) long, 4 feet, 7.2 inches (1.402 meters) in diameter, and weighs 4,460 pounds (2,023 kilograms).

7 July 1965: The McDonnell Aircraft Corporation delivered the 1,000th production F-4 Phantom II, an F-4B, to the United States Navy. Phantom II MSN 1034 was an F-4B-23-MC Phantom II, assigned Bureau of Aeronautics serial number (“Bu. No.”) 152276.
The fighter was assigned to Marine Fighter Attack Squadron 314 (VFMA-314), the “Black Knights,” at Da Nang Air Base, Republic of South Vietnam. On the morning of 24 January 1966, Bu. No. 152276 was flown by Captain Doyle Robert Sprick, USMC, with Radar Intercept Officer 2nd Lieutenant Delmar George Booze, USMC, as one of a flight of four F-4s assigned to drop napalm on a target 7 miles (11 kilometers) southwest of Hue-Phu Bai.
At 10:05 a.m., Captain Albert Pitt, USMC, flying F-4B-22-MC Bu. No. 152265, with RIO 2nd Lieutenant Lawrence Neal Helber, USMC, radioed that he, in company with Captain Sprick, was off the target and returning to Da Nang.
Neither airplane arrived. A search was started at 11:00 a.m. The two-day search was unsuccessful. It is presumed that the two Phantoms collided. All four aviators were listed as missing, presumed killed in action.
7 July 1962: Colonel Georgy Konstantinovich Mosolov, Hero of the Soviet Union, flew the Mikoyan-Gurevich E-152\1 to a two-way average speed of 2,681 kilometers per hour (1,666 miles per hour), setting a Fédération Aéronautique Internationale (FAI) World Record for Speed Over a 15/25 Kilometer Straight Course.¹

The E-152\1 (also known as Ye-152-1) was a prototype interceptor, similar to the production MiG-21. In documents submitted to FAI, the E-152\1 was identified as E-166. Colonel Mosolov made the first flight of the E-152\1 on 21 April 1961. The aircraft displayed at The Central Museum of the Air Forces at Monino, Russia, as E-166 is actually the E-152\2, sister ship of Colonel Mosolov’s record-setting prototype.
This airplane set two other FAI world records. Test Pilot Alexander Vasilievich Fedotov flew it to 2,401 kilometers per hour (1,492 miles per hour) over a 100 kilometer course, 10 October 1961; ² and on 11 September 1962, Pyotr Maksimovich Ostapenko set a world record for altitude in horizontal flight of 22,670 meters (74,377 feet feet).³
The Mikoyan Gurevich E-152\1 is a single-place, single-engine delta-winged prototype all-weather interceptor. It is 19.656 meters (64.448 feet) long with a wingspan of 8.793 meters (28.848 feet). The leading edge of the wings are swept back to 53° 47′. The empty weight is 10,900 kilograms (24,030 pounds) and takeoff weight is 14,350 kilograms (31,636 pounds).
It was powered by a Tumansky R-15B-300 turbojet engine producing 22,500 pounds of thrust (100.085 kilonewtons) with afterburner. This was the original engine for the MiG-25.
Maximum speed Mach 2.82 (3,030 kilometers per hour, 1,883 miles per hour) at 15,400 meters (50,525 feet). The service ceiling is 22,680 meters (74,405 feet). Internal fuel capacity is 4,960 liters (1,310 gallons), and the E-152\1 could carry a 1,500 liter (396 gallon) external fuel tank. Its range is 1,470 kilometers (913 miles).
After a two-year test program, E-152\1 and its sistership, E-152\2 were converted to E-152M\1 and E-152M\2.
Mikoyan Gurevich E-152\1Colonel Georgy Konstantinovich Mosolov, Hero of the Soviet Union
Georgy Konstantinovich Mosolov was born 3 May 1926 at Ufa, Bashkortostan, Union of Soviet Socialist Republics. He was educated at the Central Aviation Club, where he graduated in 1943, and then went to the Special Air Forces School. In 1945 he completed the Primary Pilot School and was assigned as an instructor at the Chuguev Military Aviation School at Kharkiv, Ukraine.
In 1953 Mosolov was sent to the Ministry of Industrial Aviation Test Pilot School at Ramenskoye Airport, southeast of Moscow, and 6 years later, to the Moscow Aviation Institute. He was a test pilot at the Mikoyan Experimental Design Bureau from 1953 to 1959, when he became the chief test pilot.
Georgy Mosolov set six world speed and altitude records. He was named a Hero of the Soviet Union, 5 October 1960, and Honored Test Pilot of the Soviet Union, 20 September 1967. The Fédération Aéronautique Internationale awarded him its Henry De La Vaulx Medal three times: 1960, 1961 and 1962. The medal is presented to the holder of a recognized absolute world aviation record, set the previous year.
On 11 September 1962, an experimental Mikoyan Ye-8 that Colonel Mosolov was flying suffered a catastrophic compressor failure at Mach 2.15. Engine fragments heavily damaged to prototype and it began to break apart. Severely injured, Mosolov ejected from the doomed airplane at Mach 1.78. He had suffered a severe head injury, two broken arms and a broken leg during the ejection and became entangled in the parachute’s shroud lines. His other leg was broken when he landed in a forest. The following day he suffered cardiac arrest. During a surgical procedure, he went in to cardiac arrest a second time.
Mosolov survived but his test flying career was over. His recovery took more than a year, and though he was able to fly again, he could not resume his duties as a test pilot.
Georgy Mosolov served as an international representative for Aeroflot until 1992. He was also a department head at the Higher Komsomol School (Moscow University for the Humanities).
Mosolov was Chairman of the USSR Hockey Federation from 1969 to 1973. He was an Honored Master of Sports of the USSR.
Colonel Georgy Konstantinovich Mosolov, Soviet Air Forces, Hero of the Soviet Union, died 17 March 2018, at Moscow, Russia, at the age of 91 years. He was buried at the Vagankovsoye cemetery in Moscow.

The Hughes XF-11 was designed to be flown by a pilot and a navigator/photographer. Its configuration was similar to the Lockheed P-38 Lightning and Northrop P-61 Black Widow, as well as the earlier Hughes D-2. The prototype was 65 feet, 5 inches (19.939 meters) long with a wingspan of 101 feet, 4 inches (30.886 meters) and height of 23 feet, 2 inches (7.061 meters). The empty weight was 37,100 pounds (16,828.3 kilograms) and maximum takeoff weight was 58,300 pounds (26,444.4 kilograms).

The XF-11 was powered by two air-cooled, supercharged 4,362.49-cubic-inch-displacement (71.49 liter) air-cooled, supercharged Pratt & Whitney R-4360-31 (Wasp Major TSB1-GD) four row, 28-cylinder radial engines. This engine had a compression ratio of 7:1. It had a normal power rating of 2,550 horsepower at 2,550 r.p.m. at 5,000 feet (1,524 meters), and 3,000 horsepower at 2,700 r.p.m. for takeoff. The R-4360-31 was 4 feet, 4.50 inches (1.334 meters) in diameter, 9 feet, 6.25 inches (2.902 meters) long and weighed 3,506 pounds (1,590 kilograms). The engines drove a pair of contra-rotating four-bladed propellers through a 0.381:1 gear reduction.
The planned maximum speed was 450 miles per hour (724 kilometers per hour), service ceiling 44,000 feet (13,411 meters) and planned range was 5,000 miles (8,047 kilometers).

After about an hour of flight, a hydraulic fluid leak caused the rear propeller of the right engine to go into reverse pitch. Rather than shutting the engine down and feathering the propellers to reduce aerodynamic drag, Hughes maintained full power on the right engine but reduced power on the left, attempting to limit adverse yaw to the right side.
Unable to make it back to the Culver City airport, Hughes planned to land at the Los Angeles Country Club. At 7:20 p.m., the airplane crashed into three houses on North Whittier Drive, Beverly Hills, California. The fire destroyed the prototype and one of the houses and heavily damaged the others. Howard Hughes was seriously injured in the crash.

The investigating board criticized Hughes for not following the flight test plan, staying airborne too long, and deviating from a number of standard test flight protocols. The cause of the actual crash was determined to be pilot error.

A second XF-11 was completed and flew in April 1947, again with Hughes in the cockpit. The project was cancelled however, in favor of the Northrop F-15 Reporter and Boeing RB-50 Superfortress, which were reconnaissance aircraft based on existing combat models already in production.
