Had a similar incident occur to me at Melbourne (Oz) a couple of years ago, when operating a leased QF B747-200 for Air Pacific.
A few minutes after all the pax had departed the airplane, and I was upstairs reading the local newspaper and enjoying dinner, we had a 2 hour turn on this occasion, there was an gigantic crash and the entire airplane shook. (Sounded just like a full galley cart falling over right next to your seat!)
I ran downstairs, those spiral staircases were great for quick descents, to find that the aerobridge supports had both failed, and the entire weight of the thing was being supported by the open door!
A quick call to maintenance got a forklift in place, and eventually the bridge was removed from the door/airplane.
So our 2+ hour turn, turned into an unplanned overnight, (don't you love those!), whilst the maintenance guys checked out the damage and got the necessary repairs done!
Cheers, FD
