Due to a problem with the gear the aircraft was towed away from the gate for maintenance. Pins were installed on all gears and the maint crew started to recycle the levers. As they did this the nose gear pin started to shake/ rattle/move out slowly. On the fifth cycle the pin dislodged itself and the rest is history!!!
Most of the damage was when the fuselage hit the GPU below. when that happened #3 eng hit the ground.
**** happens and i hope the ground guys survive the inquiry.
