OT: skok ze stratosfery

[Pavel KREJCI]

Je tam popis co by se melo stat pri ktere vysce jak pri stoupani, tak
pri seskoku.

DESCENT

115,000 feet / 35.050 meters: From Felix’s jump until he reaches this
altitude, the air is almost a vacuum; so thin that he will have no
resistance to work against – he won’t be able to control his position.
Once he descends below 115,000 feet / 35.050 meters, he will gradually
begin to be able to use his body to control his position and will
attempt to achieve a streamlined, head-down “Delta” position before
breaking the speed of sound.

107,000–102,000 feet / 32.613–31.090 meters: If Felix goes supersonic,
it will likely be in this altitude range.
