Virgin's pioneering tourist-carrying spacecraft crashed on a test flight in California on Friday, killing a pilot and scattering debris across the desert—and raising questions about space tourism's future.
Television images showed the wreckage of SpaceShipTwo, a test vehicle that flies to the edge of space, amid brush east of Mojave, a few hours' drive northeast of Los Angeles.
"Space is hard and today was a tough day," Virgin Galactic chief executive George Whitesides told reporters at a media briefing a few hours after the crash.
"When we have a mishap from the test community, we find the test community is very small... and we are human, and it hurts," added Stuart Witt, head of the Mojave Air and Space Port.
The incident is the second disaster involving a US spacecraft this week, after an unmanned Orbital Science rocket carrying supplies to the International Space Station exploded after launch on Tuesday.
It is also a huge blow to British tycoon Richard Branson's long-held dream of offering the first passenger space flights, which have been snapped up by Leonardo DiCaprio and other celebrities.
The Virgin chief said he was heading straight to the site, as the California Highway Patrol confirmed that one pilot had died and another was seriously injured and taken to hospital.
"Thoughts with all @virgingalactic ... I'm flying to Mojave immediately to be with the team," he wrote on Twitter. Whitesides later said that the globe-trotting tycoon was due in Mojave by Saturday morning.
Reserved seats
The spaceship had been carried aloft on a bigger aircraft known as WhiteKnightTwo and then released for a test of its rocket engine above the Mojave desert, the latest in a series of tests.
Witt told reporters that WhiteKnightTwo took off at 9:20 am, and released SpaceShipTwo at an altitude of 45,000 feet (13,700 meters), at 10:10 am, after 50 minutes of flight.
Two minutes later, Witt said it became clear as he watched from the space port that something had gone wrong, even though there was nothing obvious visually from the ground.
"If there was a huge explosion, I didn't see it," he said. "From my eyes and my ears, I detected nothing that appeared abnormal."
The National Transportation Safety Board air safety agency said it was sending a team to the site of the crash.
The flight—the 35th by SpaceShipTwo, according to Virgin Galactic's Twitter feed—involved the same configuration as previously, although the type of fuel was new, officials said.
More than 500 people have already reserved seats—and paid a deposit on the $250,000 ticket price—for a minutes-long suborbital flight on SpaceShipTwo, which can carry six passengers.
The SpaceShipTwo's first commercial flight—in which Branson and his family have vowed to travel—has been repeatedly delayed, but was tentatively forecast for the first half of 2015, before Friday's crash.
DiCaprio and fellow actors Ashton Kutcher and Demi Moore are among those already reported to have booked their place.
In May, DiCaprio auctioned off an invitation to join him on a trip with him into space, raising 700,000 euros ($876,000).
Private companies are rushing to fill the gap left by NASA, which ended its 30-year shuttle program in July with the completion of the final Atlantis mission to the International Space Station (ISS).
Analysts said the accident is a huge blow to the nascent industry.
"It's a setback for the tourism industry," said Marco Caceres, an analyst and director of space studies for the Teal Group, a defense and aerospace consultancy just outside of Washington, DC.
"You are not going to see any commercial space tourism flight next year or probably several years after that," he told AFP.
But Witt said the commercial space industry, and all the young entrepreneurs working in it must move beyond the tragedy.
"My message to them is stay the course," he said.
Whitesides echoed the sentiment, saying: "We're going to get through it. The future rests in many ways on hard days like these."
Reality TV
NASA voiced shock at the crash.
"While not a NASA mission, the pain of this tragedy will be felt by all the men and women who have devoted their lives to exploration," said NASA Administrator Charles Bolden.
"Space flight is incredibly difficult, and we commend the passion of all in the space community who take on risk to push the boundaries of human achievement."
The Virgin crash also raised questions over a reality TV show, "Space Race."
The show, which was commissioned last year, pits contenders against each other to win a flight on the Virgin Galactic spacecraft, according to entertainment industry journal Variety.
Initial investigations into the earlier Orbital Science rocket explosion centered on the pair of rocket engines providing its thrust, which were made during the Soviet era and refurbished.
