Dan Air lost one when the flap cross shaft sheared allowing one side flaps to retract on landing.
There were some spectacular pictures of this where it scythed across several aircraft....
it was a BKS a/c on a horse charter in summer 1968 at LHR
it sliced thru 2 BEA tridents and crashed into the britannic building
(now terminal 1)
the f/d crew were killed and the loadmaster i think
