Branson insisted Saturday his dream of commercial space travel was still alive though he will first focus on causes of the spacecraft crash that killed one pilot and seriously injured another.
Speaking to reporters after arriving in the California facility that had served as the hub of Virgin Galactic's space program, Branson said safety remained his paramount concern.

"We owe it to our test pilots to find out exactly what went wrong, and once we've found out what went wrong, if we can overcome it, we'll make absolutely certain that the dream lives on," a grim-faced Branson told reporters.
"We do understand the risks involved, and we're not going to push on blindly," he said. "To do so would be an insult to all those affected by this tragedy.

"Safety has always been our number one priority," he added before heading off to rally grieving Virgin Galactic staff.

Branson's comments at the Mojave Air and Space Port came as a team of federal investigators began probing the causes of Friday's accident, which dealt a devastating setback to the cause of commercial space tourism.
The crash saw the company's suborbital SpaceShipTwo break apart and hurtle to the ground shortly after it had detached from a mothership at an altitude of around 45,000 feet (13,700 meters) during a test flight.

The Los Angeles Times identified the pilot killed in the crash as 39-year-old Michael Alsbury, a father of two.
The crash was the second disaster to rock the private space industry in the space of a few days, after an Antares rocket carrying supplies to the International Space Station exploded after take-off in Virginia in Tuesday.
Space tourism grounded:
Experts say the accident will delay the advent of commercial space tourism by several years.
Virgin Galactic had hoped to start ferrying wealthy customers to the edge of space in 2015, charging $250,000 per person for a ticket on the company's six-seater vehicle.

As investigators launched their probe, early attention had been focused on a new kind of fuel being used in the doomed flight, the 35 by SpaceShipTwo.
The plastic-based fuel had been tested on the ground before but not in flight.
The accident was not the first tragedy to strike the Virgin Galactic program.
In 2007, three people were killed after a rocket designed for use in SpaceShipTwo exploded during testing.

Witnesses to the latest accident said there was no obvious sign of an explosion from the ground.
Private companies are rushing to fill the gap left by NASA, which ended its 30-year shuttle program in July 2011 with a final Atlantis mission to the International Space Station.
Analysts said the latest accident is a huge blow to the nascent industry.
