Så här skriver AV Web idag på morgonen:
The B-2 Spirit "Stealth Bomber" that crashed Saturday, Feb., 23, at Andersen Air Force Base, Guam, was on fire prior to the crash, according to a report cited by the Air Force Times. The fire, which was reported shortly after takeoff, was followed by an uncommanded and uncontrollable roll to the right. The aircraft crashed between the ramp and taxiway at approximately 10:45 a.m. local time, and not before both pilots had safely ejected. One of the pilots suffered spinal compression and as of Thursday remained in the hospital. The crashed aircraft, the Spirit of Kansas, a part of the 509th Bomber Wing, had more than 5,000 flight hours. The remaining fleet is not "grounded" but under a "safety pause," according to the Air Force -- the aircraft could be called to service if tasked with a mission. During the safety pause, six B-52s have arrived "to replace" the remaining three B-2s in Guam.

Kommer sakna "Spirit of Kansas" då det var den maskin man stod och begapade på Fairford 1997 och som man av en trevlig besättning fick en guidad tur kring.

Haveri B-2 "Spirit of Kansas"
Här finns en hel del information om haveriet, samt filmer och animationer på haveriet
http://www.acc.af.mil/accspecialreports ... nboard.asp
Fukt i flygplanets luftdatasystem verkar ha varit orsaken.
Moisture in the aircraft's Port Transducer Units during air data calibration distorted the information in the bomber's air data system, causing the flight control computers to calculate an inaccurate airspeed and a negative angle of attack upon takeoff. According to the report, this caused an, "uncommanded 30 degree nose-high pitch-up on takeoff, causing the aircraft to stall and its subsequent crash".
I filmen/länken "B-2 crash from security camera" får man först se en normal takeoff med en annan B-2, och sedan "Spirit of Kansas´" takeoff. Här ser man den mycket kraftigare upptagningen "uncommanded 30 degree nose-high pitch-up on takeoff".
