New fabric acoustical protection being used inside the fairings now for more clearance and protection.
Congratulations to ULA & partners on a perfect launch!That 551 does get off the pad in a hurry, doesn't it? Lovely to watch.
I captured something that seems interesting - one of solids barfed a large piece of unburned fuel. Is this normal?

Quote from: Targeteer on 06/24/2016 03:26 pm1. I got about 4:30 from the launch replay video--ignition at 0:56, cutoff at 5:26 (not totally accurate due to commentator delay.) The launch aritcle lists the burn as 4:25.6.Atlas burns to depletion so no worries about a long burn there. I guess a really long burn could mean an underperforming powerhead on the engine and thereby gravity losses, but <5s is attributable to other variables.
