So let me get this straight, a little bit of "moisture" cause a billion dollar aircraft to crash....

Having worked around B-2's when I was stationed at Edwards AFB I do know about those sensors.
Those air pressure sensors work just like a MAF. They have a heater element in them to burn off moisture. Just like our MAF's do. However I don't know there calibration routines. If the maint. T.O.'s called for only taking an impedance reading with the heater circuit off then yes. Any moisture in them would throw off the baseline reading.

10 to 1 odds a revision to the T.O. was issued to power the heater on to burn off moisture before recalibration procedures. What gets me is, how the hell did they figure out it was moisture in the sensors during routine maintenance and not just a failure of the heater elements in them before take off?

What did you do there?

I am an Ex-AMMO troop (IYAAYAS!!). Worked out on south base in the bomb dump. Delivered a lot of munitions to the B-2 Barn on south base. Which put me in, under, and around them quite often.
The B-2's spent like 4 years on Edwards doing conventional munition load out certifications and T.O. Verifications.
Ya know how it is on Edwards... Test it, turn a screw then test it again.
