Hard to watch how the colleagues dragged the poor guy with probably broken legs over the tarmac to a location under the wing. The other bystanders did not seem to be concerned at all. With such a fire the place under the wing would be the worst place to be. What will those guys do in a more demanding emergency?
That is exactly the safest place to be in the initial minutes when you expect emergency vehicles to arrive to knock the fire down.
I have been out in the middle of JFK field in my own personal car (no radio) attending to a B747 freighter emergency that was sitting on 16 flat tires. With all the plane traffic around me I decided to just park my car under a wing to be sure I was not interfering in traffic
