If you’ve ever wanted to be a fly on the wall of a space shuttle during launch, go to this video.
At about the 47 second mark, the SRBs (Solid Rocket Boosters) separate. If you look closely at the right-side booster, it looks for a moment like you can see hot gases leaking from the seam of the nozzle segment as it rotates.
An SRB segment leak of hot exhaust gases was the prime cause of the 1986 Challenger shuttle disaster.
Anyone know for sure if that’s what we’re seeing?
