All airliners have ABS (well, it's not called ABS but you get the idea), so brakes can't lock and not release. You don't need anything abnormal for brakes to catch fire. All ops manuals give the minimum time to wait after landing (or aborted take-off) before taking off again. If you go below that, you might get brake fire on an aborted take-off. The air temperature is a factor (obviously cools slower in hot temperatures). And it helps to use the right grease

And one more thing for the geek factor: aircraft certification requires a minimum time for brake fire not being able to spread to the fuselage. I think it's five minutes, but don't quote me on that!

Isn't the "Pax Gone" pic just as the first door was opened?

Yes indeed, just being deployed. Good call by the captain to not evacuate via the left-hand side!

You are both right! I should have called it.... pax waiting to get out.... or just... no pax.....
But why with so much fire-trucks didn't they wait for a stair-truck?? I mean, it looks like everything was under control.

Fire under the wings is very dangerous, if the fuel or fuel-vapours catch fire it can cause a big disaster. Better to evacuate and bring your passengers to safety then waiting for a stair-truck that -most likely- will not show up in the next 15 mins.

I thought emergency slides were yellow?

It is called antiskid, a sort of enhanced ABS if you prefer...

Nope, grey can be the colour as well

From reports I've heard, they were using grease that did not meet the Boeing spec for that Aircraft .
