Here is the video of that USAF B2 that crashed in Guam last February 2008.
The first B2 took-off without incident.
The security camera pans to the left to catch the second B2 rolling down the runway and you can see that B2 rotate much much earlier than the first B2. You can also see it pitched at a steeper angle and, note, the control surfaces moving furiously. I think the pilot attemted to pitch-down the aircraft, you can see it in the video, to increase airspeed and prevent stall.
It looked like the left wing was scrapping the ground when both pilots ejected.
