A US businessman who blasted into space with Star Trek actor William Shatner has died in a plane crash less than a month later.
Glen de Vries, 49, was aboard a single-engine aircraft which crashed in woodland in the US state of New Jersey on Thursday.
The other person on the flight, Thomas Fischer, 54, was also killed.
Mr De Vries, who joined Mr Shatner on Amazon founder Jeff Bezos's New Shepard spacecraft, was a tech entrepreneur.
The Cessna 172 plane crashed in a wooded area of a state park near Lake Kemah, about 40 minutes before sunset, according to the Federal Aviation Administration, which is investigating the crash.
Mr Bezos tweeted that he was "heartbroken".
Such a tragic loss. Warm and full of life, Glen made us laugh and lit up the room. He was a visionary, and an innovator – a true leader. Lauren and I are heartbroken and will remember the precious time we got to spend together. (1/2) pic.twitter.com/AYKCGIUQfD— Jeff Bezos (@JeffBezos) November 12, 2021
