There are always fun surprises uncovered when researching patches, sometimes where you least expect it. The STS-76 patch is no exception. At first glance the STS-76 appears to be a standard crew patch, issued in the midlife of the shuttle program. The "76" number was used to commemorate the signing of the US Declaration of Independance so the colors are clearly patriotic in red, white and blue and there is much standard symbolism, from the 13 stars to the stars and stripes.
