STS-84 A-B Emblem Variations


There are two distinct variations of the STS-84 crew patch. The differences are actually quite substantial for a patch of this type. A curious thing about this patch is that the rarer variation was flown but not work by the crew on their orange escape suits. I cannot find any evidence that the crew wore this patch, but I do have the variation in KSC packaging as well as in flown presentations. You can see the differences in the yellow flame and in the stack lines of the SRBs.
