When Virgin Galactic founder Richard Branson became the first billionaire to fly to space with his own company on July 11, he may have also come close to becoming the first billionaire to crash during a spaceflight, according to a report from The New Yorker.
The mission, called Unity 22, saw Branson and four other passengers fly to space on Virgin Galactic’s SpaceShipTwo space plane VSS Unity, which was piloted by the company’s veteran pilots Dave Mackay and Mike Masucci. After a carrier aircraft called WhiteKnightTwo lifted VSS Unity to an altitude of 50,000 feet (15,000 meters), the space plane separated from its mothership and ignited its rocket engines, sending the craft soaring up to 53 miles (86 km) above Earth’s surface, where the crew experienced about four minutes of weightlessness before heading back to Earth via an unpowered glide flight.
Nearly one minute into VSS Unity’s powered flight, a yellow warning light appeared on the space plane’s console indicating that the craft was veering off course “The light was a warning to the pilots that their flight path was too shallow and the nose of the ship was insufficiently vertical,” The New Yorker report by writer Nicholas Schmidle states. “If they didn’t fix it, they risked a perilous emergency landing in the desert on their descent.”
The New Yorker report is based on interviews with eight unnamed Virgin Galactic officials who are “knowledgeable about the program,” the report states. Virgin Galactic did not immediately reply to Space.com’s request for comment.

Just a few seconds before the minute-long engine burn was complete, another warning light appeared on the console — this time a red light indicating a so-called “entry glide cone warning.” The term refers to the cone-shaped trajectory of VSS Unity during its glide flight back down to Earth, and the red warning light “should scare the crap out of you,” Masucci once said during a Virgin Galactic pilots’ meeting in 2015, according to The New Yorker.
Because VSS Unity was not descending at the correct angle, it had veered outside of this cone and outside of its mandated airspace, putting it at risk of an emergency landing or even a collision with other aircraft. Virgin Galactic officials told The New Yorker that VSS Unity had in fact “deviated from its Air Traffic Control clearance” for 1 minute, 41 seconds and that an “investigation is ongoing.”
While multiple sources within the company told The New Yorker that the safest course of action would have been to abort the mission — powering down the engines and returning to Earth before reaching the maximum planned altitude. But one Virgin Galactic spokesperson disagreed that an abort was the safest option, the report states. Virgin Galactic did not immediately reply to Space.com’s request for comment.
There was no abort, and thankfully the skilled pilots of VSS Unity were able to get the passengers to and from space safely, and the space plane returned to Earth with a smooth, space shuttle-style touchdown at Spaceport America in New Mexico.
July’s flight was the first time that SpaceShipTwo carried a full crew of passengers to space, but it certainly wasn’t the first time that a SpaceShipTwo mission experienced dangerous technical problems. An earlier test flight in 2014 infamously killed one pilot while injuring another, and there have been at least two close calls since then.
During one test flight in July 2018, Mackay and Masucci lost control of the space plane as they flew through Earth’s mesosphere for the first time, according to the New Yorker. They regained control and landed safely, but “a post-flight inspection exposed manufacturing defects that required months of repairs,” the magazine’s Nicholas Schmidle reported.
Then when Virgin Galactic put its first passenger on board SpaceShipTwo for a test flight in 2019, “the ship sustained significant damage when a bond holding the trailing edge of the horizontal stabilizer came unglued,” The New Yorker added. In a 2020 interview, Virgin Galactic’s then vice-president of safety Todd Ericson told The New Yorker, “I don’t know how we didn’t lose the vehicle and kill three people.” When it seemed that Virgin Galactic management had swept the incident under the rug, Ericson left his position at the company in frustration, according to The New Yorker.
Another well-respected Virgin Galactic pilot who voiced concerns over the company’s safety practices has also recently left the company, but he was fired over Zoom, The New Yorker reported. Virgin Galactic’s lead test pilot and flight-test director Mark Stucky criticized Virgin Galactic’s management in a book published in May 2021 by Nicholas Schmidle (who also wrote The New Yorker’s report). After the book was published, Stucky “was stripped of his flight duties and excluded from key planning meetings” pertaining to the July 11 mission, and he was fired eight days after the flight, according to the New Yorker.
After the apparent success of the July 11 flight, Virgin Galactic resumed selling space tourism tickets on its SpaceShipTwo, raising the price nearly twofold to $450,000 per seat.
The company plans to launch its next SpaceShipTwo mission in late September, this time carrying a crew from the Italian Air Force to suborbital space. After that flight, Virgin Galactic plans to ground its mothership VMS Eve for eight months for “enhancements,” the company announced last month.
