HICKAM AIR FORCE BASE, Hawaii (AP) — The first crash of a B-2 stealth bomber was caused by moisture in sensors and estimated the loss of the aircraft at $1.4 billion.  The crash could have been avoided if knowledge of moisture evaporation techniques had been explained throughout the B-2 program, Air Force officials said.  Instead, the Air Force stopped flying B-2 stealth bombs for two months after the crash until officials finally figured out the cause of aircraft’s failings.  For more details on this, click here and return back to comment.
