My first flight at the G-spot (my first freighter flight ever) was on the DC-10, Oakland to Anchorage, in 1999.
The professional flight engineer was an attractive blonde woman in her thirties who was a KC10 veteran.
As soon as we got the doors closed she changed into a T shirt. It said, "I can't even THINK straight."
That was my introduction to the cargo business.
(She later introduced me to the F street, Ei tai won in Seoul and how to drink OB Lager. Great girl. I hope somebody switched her back over.)
