Chuks,
A 200 once carried 27 pax out of Kuito, Angola, when the latter was being attacked by Unita. Refugees stormed all available aircraft on the ramp, it was completely impossible to get the people off again. (I don't blame the poor bastards, everybody was taking it in turns trying to wipe them out!)
Aircraft taxied out with the door dragging and a pilot on the steps fending off more refugees. Top right corner of the door was ground away through contact with the tarmac. Aircraft got out ok and made it back to Luanda, albeit at a low altitude and unpressurised.
Civil Aviation (in country of registration) notified, airframe inspected, door fixed, carry on chaps...
Amazing aircraft.
