Its the second one taking off, pretty amazing video: http://www.liveleak.com/view?i=f6d_1212714828 (http://www.liveleak.com/view?i=f6d_1212714828)

Wholly pitch up
-
Yeah, I think he needs a few more rides in the simulator playing with his elevator trim...

it could be a runaway trim tab
-
wheels up, pull back on stick as hard as you can... :huh
-
Good to see the crew got out in time!
Must have been some configuration error, software/hardware malfunction, or both.
-
3 of the 24 sensor's were blocked by moisture causing the aircraft to think it's nose was pointing down hence the huge pitch up , crew were lucky

I remember the news stories at the time saying it crashed shortly after take off,but not that short.

B-2 crashed because moisture confused sensors

The most expensive crash in Air Force history — the $1.4 billion loss of a B-2 Spirit bomber Feb. 23 — was caused by water clogging aircraft sensors, according to an Air Combat Command report issued Thursday.
Moisture in three of the 24 sensors that feed information into the bomber’s computer system caused the sensors to send bad information about the plane’s speed and altitude, and how far up or down the bomber’s nose was pointed.
As the jet took off from Andersen Air Force Base, Guam, the onboard computer thought the B-2 was pointed downward, causing the nose to jerk suddenly upward.
The two pilots couldn’t regain control of the bomber and as the left wing struck the runway, the pilots safely ejected.

The investigation didn’t fault the performance of pilots Maj. Ryan Link and Capt. Justin Grieve, both assigned to the 509th Bomb Wing at Whiteman Air Force Base, Mo. The report also cleared maintainers of any missteps.
Maintainers were aware that high humidity on Guam could result in sensors clogging up with water but thought the sensor problems were solved prior to takeoff. Also, the pilots saw no avionics readings that would have led to aborting the takeoff.

We taxpayers want our $1,200,000,000 back. :mad:

What a stupid horrible unnecessary waste. He who lives by sensors dies (or is seriously inconvenienced) by sensors.
-
Well the F-22 is covered in em, me hopes those sensors were big bucks to bring a B-2 down. Let's pray it wasn't some $19.95 parts!
-
I wonder if it's a software issue to allow the pilot to over ride the computers in flight. I can't see it being anything but helpful in this case. If the pilot had been able to overide the controls he could have saved a pricey aircraft.
-
Due to the nature of the B2 and it's inherent instability flying without the aid of computers is not an option :(
-
I would like to see someone try though! :rofl
F22 has suffered PIO, the SAAB JAS 39 Gripen as well. What about the V-22 Osprey? I recall seeing a film with it crashing in what looks to be caused by a PIO.
Computers are only as good as you program them to be.
-
The PIOs on the F22 vid are a computer glitch when they were working out the FBW.
It was early testing and it bellied in fine.

a little duct tape and bondo, and it will all be better... :aok
