TRUTH OR CONSEQUENCES, N.M. (AP) — Virgin Galactic is taking its first space tourists on a long-delayed rocket ship ride, including a former British Olympian who bought his ticket 18 years ago and a mother-daughter duo from the Caribbean.

The flight window opens Thursday morning at Spaceport America in the New Mexico desert for a ride to the edge of space. If all goes well, Richard Branson’s company will begin offering monthly trips to customers on its winged space plane, joining Jeff Bezos’ Blue Origin and Elon Musk’s SpaceX in the space tourism business.

Virgin Galactic passenger Jon Goodwin, who was among the first to buy a ticket in 2005, said he had faith that he would someday make the trip. The 80-year-old athlete — he competed in canoeing in the 1972 Olympics — has Parkinson’s disease and wants to be an inspiration to others.

“I hope it shows them that these obstacles can be the start rather than the end to new adventures,” he said in a statement.

Ticket prices were $200,000 when Goodwin signed up. The cost is now $450,000.

He’ll be joined by sweepstakes winner Keisha Schahaff, 46, a health coach from Antigua, and her daughter, Anastatia Mayers, 18, student at Scotland’s University of Aberdeen. Also aboard the plane-launched craft, which glides to a space shuttle-like landing: two pilots and the company’s astronaut trainer.

It will be Virgin Galactic’s seventh trip to space since 2018, the first with a ticket-holder. Branson, the company’s founder, hopped on board for the first full-size crew ride in 2021. Italian military and government researchers soared in June on the first commercial flight. About 800 people are currently on Virgin Galactic’s waiting list, according to the company.

Virgin Galactic’s rocket ship launches from the belly of an airplane, not from the ground, and requires two pilots in the cockpit. Once the mothership reaches about 50,000 feet (10 miles or 15 kilometers), the space plane is released and fires its rocket motor to make the final push to just over 50 miles (80 kilometers) up. Passengers can unstrap from their seats, float around the cabin for a few minutes and take in the sweeping views of Earth, before the space plane glides back home and lands on a runway.
