B-2 Crash Cause Revealed

The cause, water on the air data sensors, giving the flight control inaccurate data.

There had been a previous incident on Guam when a pilot aborted takeoff, and the solution was to turn on pitot heaters to dry off the sensors, but this was never adopted as a formal part of the checklist.

It was an "underground procedure".

You know, I would think that on an aircraft that is literally worth its weight in gold, that they would get their maintenance act together just a bit more.

The video of the crash follows, with the 2nd aircraft being the one that crashed.
