QU8k
For the record, at 121,000 feet–23 miles–the pressure is only 93 pascals. Since the triple point of water is 611.73 pascals, if a desert rat had stowed away on Qu8k its blood would have boiled in its body at body temperature. The density of the air is low too: 0.005 times that of the air at sea level. Notice that your ejected drogue line did not become taut quicky. The average air temperature there is -32 Celsius.
I had fun identifying some of the various geographical features of Northern Nevada and Northern California in your video. The geometric horizon is 685 km ( 428 miles) away, approximately. So you should be able to see Lassen peak and the Pacific ideally.
