I have a different recollection than Step Turn about the handling of the Air France evacuation. I seem to remember the cabin crew being highly commended and that is backed up by the report on Wikipedia. I looked it up because the events are some time ago and I wondered if I was confusing events. In this case I think Step Turn may be doing so.
From a european perspective suing the airport because you run off the end of the runway sounds very strange. The only logic would be to try and persuade people who do not know much about aviation (e.g. most passengers) that they are a safer airline than their accident record suggests.
