It's all too easy to forget how high up the sill is - in GVA on an MD-80 a hostess held the leather strap and leant out - the single self tapping screw pulling away. She also hit her head and was injured. This lousy construction was meant to steady the cabin crew member while shutting the door.
In BCN, where the jetty has an acute angle and slope, where it abuts the ship, I have seen pax stumble and fall against the jetty window (a sheet of perspex, which could give way).
A lady pax fell from the steps disembarking a DC-10 and was unfortunately fataly injured in ZRH.
Best of luck with the recovery. And let's take care out there.
