Good Point:
"The American Air Force defines an astronaut as an individual who has flown over 50 miles above the mean sea level (between the thermosphere and the mesosphere). NASA used FAI’s figure (62 miles) until 2005 when they changed to 50 miles to get rid of inconsistency between civilians and military personnel flying the same spacecraft. Recent work by Gangale Thomas and Jonathan McDowell advocate for the Karman line to be shifted from 62 miles to 50 miles, citing Theodore Karman’s calculations and notes as evidence. Their findings forced the FAI to propose a meeting with the IAF to explore this issue in 2019.
