N355MC 747-300 of Atlas Air...Landing gear was retracted by engineer on stand with no bypass pin resulting in the aircraft initially to pitch up in takeoff position and then when the main gear could retract no further the nose came crashing down onto the apron causing major damage to the already retracting nose gear and bay doors. Luckly no one was injured.
2 Cranes and lots of airbags are currently trying to rectify the situation. The aircraft had around 115 tonnes of cargo loaded at the time...ouch!
