I've never seen flames coming out the back of the shuttle, day or night,
before...

Yep; it's bright, but normal. I don't think it's flames - more steam (APU's
run on hydrazine, I think - the 'waste' from that is water vapour).

Maybe running a little rich? (That's a joke) The dual exhaust vents at
the base of the tail look more or less normal.

It's snowing outside my bedroom window as I watch the landing and wrapup
on my computer monitor. Somewhere I >know< it's Spring...

Nope, it's ammonia and hydroge
--no oxygen involved until the hot gas
hits the atmosphere...

Yeah, the infrared night movies I've seen of it are pretty cool, you can see
it "chugging".

There was one point of view where you could clearly see that those
"flames" illuminated the shuttle, especially the tail. Couldn't have
been just vapour. And the flames were dancing around.

On the other hand, the view from the front of the shuttle showed 2 clean
plumes of steam coming straight up and not dancing at all.

Are they not effectively gas turbines? You get very, um hot exhaust from
those, Toasted donunts anyone?
