S.F. man's astounding photo Mysterious purple streak is shown hitting Columbia (Feb. 5)
Boot Hill and Sabertooth first suggested sprites in the thread. I remembered Blam's thread about this shuttle actually investigating sprites.
Blam's January 21 thread:
It will be real interesting to see what NASA makes out of the photos that CA astronomer captured. Part of the problem for them will be the dearth of knowledge about sprites, jets and elves. All the speculation about damaged tiles might just turn out to be a blind alley.
