That's quite a serious brake fire, and certainly cause for an evacuation. But what a shambles.

The rear tailcone emergency exit is a feature of the MD-80 series, but it's jettison should be followed by deployment of an inflatable rear-facing slide, which never happened. He's an example of an engineer testing one himself.

The number of passengers who took their rollaboards down the rear slide is just unacceptable, including it seems the second passenger to escape. They stand a good chance of puncturing the inflatable slide with their wheels etc - which is why high-heeled shoes have to be taken off.

None of the passengers stood at the foot of the rear slide to assist those following.

The landing aircraft that passes at speed on the immediately adjacent runway (looked again and saw it is a landing - full flaps and spoilers deployed) AFTER the fire service vehicles arrive and start tackling the fire is completely unacceptable, there were loose passengers running away from the fire right alongside there, ATC should have stopped everything, and sent any landing aircraft around, the moment the emergency was called.

The fire crews seem poorly trained in aiming their fire jets; any crews with that inaccuracy performance at the UK fire training school would never be passed out of the course. A classic example of hugely expensive fire vehicles, and then no money left in the budget to develop capable crews.
