100Km is about 328,000 feet. That's why Space Ship One had a tail number of N328KF.
Also, the North Texas Balloon Team and the South Texas Balloon Project routinely (with launches approximately annually) send balloons with video cameras to altitudes in excess of 100,000 feet. Those are just the two balloon projects I'm familiar with. I am sure there are others because it's not particularly hard to do.
So, this is pure ho-hum to me. Let me know when they've done it a couple of dozen times.
