30+ years at it from Electras through to 747/400s and only twice was i shaken up badly..both strikes..one on descent into ATH..rhs of 747 struck between R1 and R2 doors..exactly where i was working..sounded as if we had been machine gunned and when the guys checked after landing, there were about 25 holes along the fuselage, even looked like large bullet holes.
Other was NAN/HNL.707/138..just the one hit... rhs again but loudest thing I've ever heard..the shakes and sweats didn't start for a couple of minutes but they lasted a bit longer.And no marks on the fuselage!
