The Air Force says it now knows what caused a military plane called "The Spirit of Kansas" to plunge to the ground back in February.
Moisture in the plane's sensors forced bad readings in the Missouri based B-2 stealth bomber on February 23rd. That caused the jet to come crashing down at Andersen Air Force base on the island of Guam.
The pilot survived with minor injuries.
The co-pilot received a spinal compression fracture during ejection. The "Spirit of Kansas" plane was the first of its kind to crash since the B-2's first voyage nearly 20 years ago.
