The F-16XL's unusual curved double delta wing platform is apparent in this photo. During the mid to late 1990s several research aircraft flew in dazzling paint finishes. A prime example was the F-15B ACTIVE, with its red, white, and blue markings. The F-16XL #1's finish in December 1997 was also eye catching. The wings, tail, and upper aft fuselage was black with yellow trim, while the forward fuselage was white.
