Billionaire Jeff Bezos blasted into space on Tuesday, in the first crewed flight of his rocket ship, New Shepard.
He was accompanied by Mark Bezos, his brother, Wally Funk, an 82-year-old pioneer of the space race, and an 18-year-old student.
They travelled in a capsule with the biggest windows flown in space, offering stunning views of the Earth.
All four passengers have now parachuted safely back to Earth after their 10-minute, 10-second trip.
New Shepard, built by Bezos' company Blue Origin, is designed to serve the burgeoning market for space tourism.
On this flight was the oldest person who has been to space - Ms Funk - and the youngest, student Oliver Daemen.
The spacecraft lifted off at 14:12 BST (09:12 EDT) from a private launch site near Van Horn, Texas.
