Proposed F-15 Thunderbirds Markings

     McDonnell Douglas made a pitch for the Thunderbirds to use the F-15 and these photos show what the color scheme might have looked like. (The second photo is a USAF F-15 2048x2048 Skin by Zimster.)

For the USA Bi-Centennial in 1976,  F-15B71-291 was painted in (Most of) the proposed Thunderbirds  scheme with the T-Bird Logo replaced by the Bi-Centennial one.
