Joe asked:
Whenever I’m at the airport and I see the 747s lined up for boarding, there is often a very hot looking exhaust coming from a port at the very rear of the tail. What is this? is there a conventional generator in the tail? or is it an additional turbine? does it operate during flight, or is it just a backup?
