2012 -- The entire fleet of U.S. Air Force C-27J cargo aircraft has been ordered grounded following a mechanical failure of one aircraft’s flight control system. The failure occurred during a training mission on July 3 and was described as a “flight control problem” in a written statement released by Air Force officials.
2011 -- Authorities at Madrid's airport have found the body of a Cuban man in the undercarriage of a plane that arrived from Havana. The man "probably died from being crushed" after apparently hiding in the rear landing gear of the Iberia flight before it left Cuba,
2011 -- Japan has ordered its diplomats not to use the aircraft in the South Korean airline Korean Air for a month, to protest against an overview of islets claimed by both countries.
2010 -- New GAO Reports:
- Commercial Aviation: Better Information about Airline-Imposed Fees and the Refundability of Government-Imposed Taxes and Fees Could Benefit Consumers, GAO-10-885T, (pdf)
- Commercial Aviation: Consumers Could Benefit from Better Information about Airline-Imposed Fees and Refundability of Government-Imposed Taxes and Fees, GAO-10-785, (pdf)
- Defense Acquisitions: Missile Defense Program Instability Affects Reliability of Earned Value Management Data, GAO-10-676, (pdf)
2001 -- A prototype Minuteman intercontinental ballistic missile interceptor successfully targeted and destroyed an unarmed Minuteman II ICBM over the central Pacific. Ten minutes after launch, the interceptor destroyed the warhead, traveling some 15,000 mph at more than 140 miles in altitude above the Earth. The 30th Space Wing at Vandenberg AFB, California, and the Ballistic Missile Defense Organization conducted the Ground-base Midcourse Defense Segment, formerly called the National Missile Defense Program, test.
1993 -- C-17 Globemaster III entered service with the U.S. Air Force.
1980 -- From Vandenberg AFB, California, the 394th Intercontinental Ballistic Missile Test Maintenance Squadron launched the last Block 5D-1 Defense Meteorological Satellite. A Thor booster failed to place it in orbit.
1977 -- A U.S. Army CH-47 Chinook was downed over the Korean demilitarized zone by a North Korean MiG-21. The CH-47's pilot was captured and the other three crew members, Robert Haynes, Joseph Miles and Ronald Wells, were killed. The pilot was released after 57 hours of captivity.
1974 -- Gen. Carl "Tooey" Spaatz, the first Chief of Staff, died at Walter Reed General Hospital at the age of 83.
1970 -- The C-5A Galaxy completed its first transpacific flight of 21,500 miles, inaugurating service to Hickam AFB, Hawaii, Andersen AFB, Guam, Clark AFB, Philippines and Kadena AFB, Japan.
1965 -- The Mariner 4 satellite sent a transmission of the first close-up photograph of Mars. It consisting of 8.3 dots per second of varying degrees of darkness. The transmission lasted for 8.5 hours and depicted the regions on Mars known as Cebrenia, Arcadia, and Amazonis. The satellite was 134 million miles away from earth and 10,500 miles from Mars.
1953 -- Austrian-American mathematician and aerodynamicist Richard von Mises died. His early work centered on aerodynamics. He investigated turbulence, making fundamental advances in boundary-layer-flow theory and airfoil design. Much of his work involved numerical methods and this led him to develop new techniques in numerical analysis. He developed the Distortion energy theory of stress, which is one of the most important concepts used by engineers in material strength calculations.
1960 -- The Congo airlift started from Evreus, France during Operation Safari.
1951 -- Boeing delivered the first KC-97E tanker to Strategic Air Command's 306th Air Refueling Squadron at MacDill AFB, Florida.
1950 -- The 35th Fighter-Interceptor Group moved from Japan to a new airfield at Pohang, thus becoming the first U.S. Air Force fighter group to be based in South Korea during the war. The 6132nd Tactical Air Control Squadron, the first tactical air control unit in the war, activated at Taegu, AB to provide forward, ground-based air control for aircraft providing close air support of U.N. forces.
1948 -- First jet aircraft to cross the Atlantic Ocean. Six de Havilland Vampire F3s of No 54 Squadron RAF, commanded by Wing Commander D S Wilson-MacDonald, DSO, DFC, via Stornoway, Iceland, and Labrador to Montreal on the first leg of a goodwill tour of Canada and the U.S.
1948 -- In the first West-East transatlantic flight of jets, 16 F-80s flew from Selfridge Field, Michigan, U.S.A., to Scotland through July 20. The trip across the Atlantic took nine hours, and 20 minutes.
1914 -- Goddard patents liquid fuel rocket. Goddard receives U.S. Patent 1,103,503. Although mainly concerned with his concept of cartridge rockets, a brief section fully outlines the concept of liquid rocket propulsion.
1894 -- Neil Campbell, a professional balloonist, flew from Horsham, West Sussex, U.K.
Flight ended on the ascent, when he was dashed against a chimney in a strong wind. He suffered a fractured skull & thigh, in addition to numerous other injuries. Spent 5-weeks in a hospital, left directly to the divorce court to request release from alimony (1-Pound/week) until he could work again.
