Yea so I just watched the space shuttle do a night landing tonight on tv. During the footage of the roll out, I couldnt help but notice that there was some flames pulsing out of the base of the tail. Does anyone know what that is? Some sort of reverse thrusters? Is it normal? Could it just be extra hydrazine burning off?

the drag chute deploying? i'd imagine there are some pyro-yechnics involved with that so that could be your flash, as for fire, you would know by now if there was a fire.

Quoting Mir (Reply 2): It's hydrazine from the APUs burning off, and while this was one of the more vibrant displays of it that I've seen, it is normal.

I will second that one
Yep, that's what it is. In the daylight you can't see the flames but still can hear the intermittent puffing sound of the exhaust.
If God had wanted men to fly he would have given them more money...
