William Shatner is among more than 7,000 people who have told Richard Branson they would gladly pay him $210,000 for a trip aboard his planned spacecraft, the entrepreneur said Friday.

Former Red Hot Chili Peppers guitarist Dave Navarro has signed up for a ride, and a Hollywood director who was not identified has booked an entire ship.

Trevor Beattie, chairman of the ad agency TBWA — responsible for campaigns such as the “Hello Boys” Wonderbra campaign with Eva Herzigova — offered to send a check as soon as the project was launched last month.

In all, more than $1.45 billion (£800 million) has been pledged — years before the Virgin Galactic spaceship is even built, Branson said.

Branson, 54, is pouring $135 million (£74 million) into his latest commercial experiment, which promises to send the paying public 70 miles above the planet to experience six minutes of weightlessness and see the curvature of the Earth.
