Wonder if any of the -37s will be bought out of the boneyard and put into private hands. Would make a nice airshow historical piece. And for fun, remove the spin strakes and paint it in early schemes.
One of the last Tweet classes at Sheppard had a kid seeking designs for a class patch. I had recommended an echelon formation of 3 Tweets flying into a sunset: Lead Tweet in the current white upper half / blue lower half scheme used from 1993-current; an all white Tweet (like in the video) as #2...such that was used from about mid-'70s to 1993; and a bare-metal Tweet as #3, representing the early years pre-mid '70s.
Don't know if it was ever used.
