one of the pics shows number 1 engine bent downwards, the fuselage is also wrinkled behind the flight deck, so it must have been travelling at quite a rate when it hit the jetway.
Actually if I had got further than the pics in the email there is this comment:
On BAE-146s, two engines have hydraulic pumps, and two have electrical generators. If you taxi the airplane on the two engines with generators, you only have a few brake applications before the accumulators run out of pressure. On the way to the gate, the voice recorder captures one guy saying if they go a little faster, they could get the nose off the ground.
They were apparently unaware that the Auto Throttles were set in Take-Off mode. As they approached the gate, they found they had no brakes (a result of being in the Takeoff mode) and proceeded to slam through the jetway. Both the aircraft and jetway appeared to be totalled.
Always remain seated, with your seatbelt fastened, until stopped at the gate.
After Monday and Tuesday even the calendar says WTF...
