NASA's Famed B-52B "Mothership" Retirement : The end of an era in aerospace history was marked Friday, Dec. 17, when NASA retired its venerable B-52B "mothership" heavy-lift launch aircraft.

50th Anniversary of the X-2: September 2006 marks the 50th anniversary of two aerospace milestones that involved both triumph and tragedy for the flight test community at Edwards Air Force Base. It was in September 1956 that the highest and fastest flights of the Bell X-2, a swept-wing, rocket-powered research aircraft were flown. Sadly, the latter of those two missions cost the life of Air Force Capt. Milburn "Mel" Apt, one of the test pilots assigned to the project.

NASA's F-104 Starfighter: With a name like Starfighter, F-104s were destined to serve NASA in the extreme regime of high-speed flight research. NASA's Dryden Flight Research Center flew Lockheed F-104 Starfighter aircraft in a wide variety of missions beginning in August 1956. Over the next 38 years, 11 were operated by NASA Dryden, at Edwards Air Force Base, Calif., with the last Starfighter flight taking place in February 1994.
