I work in the oil and gas industry, and was in an emergency evacuation down the aircraft slides. Knowing what 200 te of kerosene could do, I ran until I dropped, as did several others. When we got our breath back, and started to chat, it turned out we were ALL from the oil and gas industry: some drillers from Shell, a few engineers from BP, and a mate and I. Incidentally, I realised afterwards (as we have been taught) we had run upwind.
All the others (including the CC) were milling around the bottom of the slides, some taking pictures on their mobiles of granny coming down and others on the phone to mum.
The evacuation was flawless, but once it was complete the crew did nothing to encourage the passengers to move away from the plane. I suggest they should have done. Just because there isn't a fireball doesn't mean there won't be one.
