That must be a bit of a nuisance for the aviators. I can just see the selection panel...
..."Hello Admiral, what have you got for me to command?"
"Well, son, we did some thinking, and ah reckon we've come up with the perfect practice vessel."
"Gee - thanks, Sir!"
"It's the Kennedy"
"Wow! A real fightin' ship, but I thought I was meant to work up to a CVN."
"You are. This is the USS Joseph Kennedy."
"Not sure I know that one..."
"Sure you do, son, it's the diplomatic vessel that runs away from harm's way."
"Oh, goody...."
This is a historical joke, by the way. US of A Ppruners please note that Britain was very glad to see the back of JK and is a dig at him, not you! Just to keep it topical to Prune, it was a little organisation caller, oh er... Fighter something that proved him wrong!
