sts-4

This distinctive version of the STS-4 patch has a blue border/twill and a lighter triangle in the shuttle path. The "i" in columbia almost looks like an "l". 

This patch is distinctive from the regular A-B Emblem STS-4 souvenir version as it was laid down on red twill rather than white. 

This variation features the astronaut names displayed on a curve rather than a straight line.

Swissartex version of STS-4. The thick red order is a big give away.

Slightly larger than the A-B Emblem crew version, but bears the same light red/pink triangle. Cloth back.

The crew version of the STS-4. Identified by the lighter red/pink triangle in the zag of the trail. The stitching in the Earth has a barred apperance where the slightly larger Lion Brothers version does not.

Getaway Special was a NASA program that offered interested individuals, or groups, opportunities to fly small experiments aboard the Space Shuttle. The program, which was officially known as the Small, Self-Contained Payloads program, was canceled following the Space Shuttle Columbia disaster on February 1, 2003.
