Written-off

23 February 2008, two US air force pilots ejected safely from their Spirit of Kansas before it crashed on the island of Guam. The crash occurred as the B-2 Stealth bomber was taking off from Andersen Air Force Base on Guam, a US territory south of Japan. This is the first crash of a B-2, a $1.2 billion aircraft. At the time, the United States Air Force had 21 bombers (before the crash). Investigators later blame moisture from heavy rains for maintenance crews improperly calibrating air-data sensors.
