Well, the ground accident doesn't surprise me one bit. I've only had to evacuate once (no nosewheel landing) and by far the most frightening thing about the whole event was standing on the runway watching a herd of fire trucks thundering towards us in a cloud of black diesel smoke - it was like watching a tsunami coming at you. Ever since I've always added suitable remarks to my crew about action to be taken after an evacuation that isn't in the ops manual.
I feel so sorry for the poor firecrew...how awful must they be feeling - as lifesavers.
Its surprising this sort of thing doesn't happen more often.
