So there's another funny thing here, which is metal expands when it gets hot. And normally your airplane materials don't get that hot because you're not going that fast. So it's fine if the metal expands a little bit. Except when it's getting this hot, the panels, the skin of the airplane is going to expand quite a bit. So that means if... They expand a lot. You have to leave a lot of room.
