Ground damage
Last year in LCA I got a broadside from a rubbish truck that had his roof doors open and drove right onto the static port and an airframe rib. Cue several days in a very nice hotel, the construction of a new rib and several pax-rescue and engineer/parts delivery flights.
After the jolt of impact I remember seeing the fella cheese it off across the apron! I suppose I'd be a bit scared if I'd just knacked a 75.
