Sounds like a successful suicide attempt.
https://abcnews.go.com/US/man-hit-killed-southwest-plane-landed-austin-airport/story?id=70576933The man who died was not an employee at the airport and hopped the perimeter fence to gain access to the runway, Austin airport spokesperson Bryce Dubee confirmed to ABC News.
"We are treating it as a security breach," Dubee said. "This is the first time we've had a runway incursion like this. We have had the occasional security breach, but no one has ever gotten onto an active runway at the airport."
Austin Police Department's airport unit later discovered "an obviously deceased adult male" on the runway, a spokesperson for the police department said.
Yep, getting hit by a big jet going faster than walking speed will do that.
