turn the heat off!
This is hilarious T-38 HUD video. This flight took place over a year ago involving a Japanese student and an IP who I believe is known as callsign Satan. It made the rounds of every other instructor desk on base, and even though I was a student not too long ago, it still gives me a chuckle.
Just for background, you cannot hear much when the afterburners are cookin in a Talon, not even your own radios. When the heat is on, it is even louder. Plus the heat comes straight from the bleed air, so it gets hot quick. Warning for bad language. Turn the heat OFF! O-F-F! What?
Thanks to Paulie for the link.
