    The heaters for the cabin air probably couldn’t keep up.

    This made me curious if planes use “free” excess heat from the jet engines, same as a car would, or if they need to burn fuel to heat the cabin. And it turns out the latter is the case, so not only could the heaters probably not keep up, attempting to even do so would have wasted a ton of fuel.
