If you get a chance to watch the replay, notice this, I just did...
The front wheels come down left of the lines, and you'll see white smoke coming from them. The pilot does a small correction, and then the front wheels align with and come into contact with the lines and BOOM, massive flames erupt shooting down the belly of the plane.
During the spaces between the lines, it goes back to white smoke, but just as soon as it hits a line the whole thing catches on fire again.
So it goes: smoke, fire, smoke, fire, smoke, fire.... as the plane skips along the dashed white lines of the runway.
Basically... The wheels etc. didn't catch fire - the runway did.
Maybe there's a better choice of paint out there perhaps?
