The second man on the moon has earned a reputation for public outbursts, and he allegedly added to that Jan. 16 with a scuffle at the airport.

Buzz Aldrin, who landed with Neil Armstrong on the moon in 1969 through NASA’s Apollo 11 mission, supposedly missed a flight from Los Angeles with Delta Airlines. He is said to have gotten into an angry confrontation with airline employees in which he picked himself up out of a wheelchair, TMZ reported.

It is not the first time Aldrin is in the news for this kind of interaction. Several years ago he made headlines when he punched a man who believes the Apollo 11 moon landing was staged after conspiracy theorist Bart Sibrel was harassing the NASA astronaut. The punch, as well as the harassment leading up to it, was caught on video. Sibrel was asking Aldrin to swear on the Bible that he really landed on the moon and, according to reports, had poked him with that book before the punch.

Last year, Aldrin was in the news when he seemed to be making skeptical or annoyed faces behind President Donald Trump as the latter spoke during a press conference to announce he was reinstating the National Space Council.

But Aldrin has also received more positive coverage for being outspoken about his support for human space exploration, including traveling to Mars.
