Swiss parachutist Mark Hauser made his first high jet jump, which reaches speeds of up to 402 km per hour, guinnessworldrecords.com reports.
Hauser had been training for several months to jump with a parachute. The training included tests that included low oxygen levels as well as extreme temperatures (average temperature is minus 40 degrees Celsius). The jump itself took place in Australia.
Jet streaming – a narrow zone of strong continuous wind in the upper troposphere (the lower, most studied layer of atmosphere). The winds reach such high speeds that commercial airlines can shorten travel time and save fuel when flying through the nether regions.
