But think about it. Heat gets generated at lower altitude. There is a
thermal lag. That heat gets dissipated at higher altitude. If you are
climbing VERY fast, the incoming air is less dense, you can set up a
cycle where heat is accumulating faster than it can be transferred due
to the denser air creating more combustion. Sort of like having an
extra boost of turbo charging. With the slower airspeed in a climb, and
if the engine is operating close to the edge of it's heat dissipation
maximum, it COULD cause overheating. Anyway, you see my point, I hope.
(Even if it is wrong in this case).

Young man...you don't have the foggiest idea about the operation
of aircraft jet engines.
