When I was learning to fly C-130s we had some late-night flights with a bunch of us new student copilots on board with an instructor. I think it was past midnight, and we were flying out of our training base in Tennessee, but over Georgia, controlled by Atlanta Center. The instructor was a character and was telling us young guys stories, probably about Vietnam, and we somehow missed a turn and were almost 20 miles off course when Center called and asked where we were going.
"Student training in progress," the IP said on the radio.
I've used that line a few times since, even when I was solo.
