Hot air balloon question

[rxtx]

I just saw this, a hot air balloon at around 17,000ft, which I thought was out of the ordinary,

My main question is, it must be pitch black, do balloons often fly at night, and how do they see where to land?

I bet they're not loving the temperature up there

It's in the Alps area - any chance they've forgotten to turn off the transponder and its actually being towed along? It's getting lower!!!
