This is the Army's Golden Knight's jump plane, a Fokker F-27 Friendship. During her second flight at the show, she came in early with engine one shut down. I'm not quite sure what happened, but they made it down and taxied back to the tarmac without issue.

This is a very loud turboprop and has an unmistakable whine from her twin Rolls Royce Tyne turborprops!
