yep, blasting down some singletrack in about '97/'98 a karrimor windstopper shell dropped into the drivetrain, wrapped the cassette and brought the freehub away, we had to pull the whole thing off, jacket and cassette still attached to get the jacket off.
springs flew into the mud, pawls hid from us in the dirt.
but when all found it went back together fine
the jacket was a little worse for wear though, a bit melty!
carefully turn and push when replacing
