Beautiful, but foreboding, isn't it?

Was this in the winter?  It suddenly occurred to me that these
"un-natural" 
flying machines have no engine, thus no heat, right?  It must get rather 
cold up there at nearly 18,000 feet, in the winter, with no heat - or is 
there some fuel fired heat of some type?

How cold have you seen it get in the cockpit, and how do you deal with it 
being that cold?  How about instruments; with that cold, do they continue
to 
work well, or are there some tricks about that?
