I remember the No.2 cabin staff trainer, who was line checking the cabin staff, offered to open 1 Door Left on arrival at YYZ.
She blew the slide inside the jetway. The meeters and greeters outside had to run for their lives!
I also remember taxiing out at LGW one day and seeing a blown overwing slide on a Continental DC-10. Now that structure would take more than 4 hours to re-pack.
I would guess that a slide gets blown just about every day of the year somewhere in the world.
