The Air Force Academy is investigating racial slurs written on a group of black cadet candidates’ message boards at the preparatory school.

Five students found the slurs written on their dormitory message boards.

The superintendent of the Academy, Lt. Gen. Jay Silveria, addressed cadets at the Air Force Academy Thursday.

He said, “There is absolutely no place in our Air Force for racism-it’s not who we are, nor will we tolerate it in any shape or fashion.”
