"The first appearance of an embroidered version of the "worm" logotype insignia seems to be that worn in 1977 by the Shuttle ALT (Approach and Landing Test) crews on their dark blue flight suits, as shown in the photo on the right.
The patch appears to be executed in white thread on blue cloth rather than having an embroidered background.
The same style of patch can be seen used on dark blue flight suits in various later photos, including in some images of the Group 8 astronauts in 1978, and in the official STS-8 crew portrait."
