A B-2 stealth bomber crashed on takeoff from Andersen AFB, Guam, on Saturday morning, the U.S. Air Force reported.

The Spirit of Kansas, Tail No. 89-0127, was the first B-2 bomber to crash from the fleet of 21 built by Northrop Grumman Corp.

The two pilots ejected. One was in stable condition with unspecified injuries at a naval hospital in Guam, while the other was released after a medical evaluation, TSgt. Tom Czerwinski of Pacific Air Forces public affairs office said.

The aircraft was one in a flight of four B-2s that was returning to Whiteman AFB, Mo., following a deployment that began Oct. 5, Czerwinski said. They were being replaced in the constant bomber presence role at Andersen by six B-52s.

The Spirit of Kansas crashed on the runway shortly after takeoff at about 10:30 a.m. local time, Czerwinski said. It was not clear whether the crew had declared an emergency before ejecting.

Skies were clear, and there was no indication that weather contributed to the crash.

The other B-2s returned to Andersen. Czerwinski said it was not clear how many of the four had taken off before the crash.

The B-2 Spirit first flew in July 1989, and the first operational aircraft was delivered in December 1993. The B-2 made its combat debut in Operation Allied Force against Serbian targets, flying nonstop missions from Whiteman.
