But see halojumper.com, West Tennessee Skydiving. Think that is that Mullins guy's place. 30k ft night jumps.
heh - based on my history with off landings on night jumps (3 of 4) or 24k jumps (1 of 1), I probably would self select out, or open high, or pick an LZ with a big margin for error.
In the right place, such a night jump would be neat, but others, missing the gain.

I made many night jumps from 12,500, but I also made one from 30,571 ft over Canada's largest airport. I took a member of my team at the time, but it was his 102nd jump, and he had never ben up at night before.
It was kind of a reward for being so faithful and always ready to do a demo with the team. I could always count on him.
We both landed alongside one of the 2 mile long runways on Pearson Intnl Airport.
I don't have my log books anymore, so can't tell you how long a freefall it was, but a day jump from 36,916 took 2 1/2 minutes of freefall before opening.

Just a reminder, if you are interested in high altitude night jump, I highly recommend you to have a high altitude course or preparation given by specialists. Those specialists are generally giving such courses for the army and airlines pilots. They use a pressure chamber for people. You have to know that at 18 000 ft, the atmospheric pressure is half of the one on the ground. That changes everything concerning your biological conditions : like oxygen availability, night vision... and the human body can be subject to hypoxy, droziness, becoming unconscious, loss of references, visual confusion, poor dexterity and even death. In a pressure chamber at pressure equivalent to high altitude, at a certain point you are not anymore able to write your name on a piece of paper.
Do a high altitude jump with knowledge and preparation.

A very important point. Night vision is one of the first things to go. (Obviously problematic on a night jump.)
