Back in the early 90's the L1 door slide was blown on Air Force One with Clinton on board. The steward originally claimed he did nothing wrong and later 'fessed up.
I watched an A310 R1 slide deploy into a catering truck in OSL years ago. Fortunately, the caterer was knocked back into the elevated truck and was not hurt. After descent though weather and a winter crossing the F/A said she couldn't get the door handle to move. The FO offered to take care of it, somehow rearmed the door and pulled.
