Fake news
This week the experimental Airbus Perlan Mission II pressurized glider got there by silently riding atmospheric pressure waves. And then it kept going – smashing the record for human flight in a winged aircraft by reaching more than 76,000 feet.
The SR-71 pilots might disagree with that record.
Perhaps CNN is talking about the record for unpowered aircraft, or for subsonic flight? Getting enough air into any turbine at such an altitude requires supersonic speed, doesn’t it?
