The craft’s
rocket was ignited at 50,000ft – nearly ten miles above sea level. The
pilots, wearing oxygen masks, were pinned against their seats by
gravitational forces as the craft accelerated at more than 900mph.
Then
disaster occurred. Preliminary investigations suggest that the rocket
ship’s folding wings – designed to slow it down and achieve safe speeds
during landing – deployed early, causing the ship to break up due to the
tremendous turbulence around the craft.
Alsbury
was trapped in the cockpit but Siebold was thrown clear of the wreckage
or somehow unbuckled his seatbelt. He then plunged towards Earth at
speeds topping 120mph.
Witnesses
reported seeing Siebold descending with part of the base of his seat
still attached. It is likely that his oxygen mask, attached to a
portable tank, remained in place. But at that altitude, the sudden
decompression and extreme G-forces would have caused him to black out in
seconds.
His
emergency parachute deployed at around 20,000ft. It is not known if he
pulled the cord or if it unfurled automatically. Both pilots were
wearing parachutes calibrated to open automatically at a certain height
in the event they became unconscious during an emergency.
Dr
Siebold, 79, explained: ‘He doesn’t know how he managed to exit
SpaceShipTwo. They don’t have an ejection seat. They have a panel they
take out and they have to crawl towards the hole and jump out. But the
plane broke up suddenly. I’m sure he was unconscious because he could
not have maintained consciousness at 50,000ft.
Co-pilot Alsbury was killed in the tragedy over the Mojave Desert
‘He
doesn’t remember anything from the actual crash. He came to during the
descent. He must have woken up about halfway down. When he was on the
way down the chase plane was circling him and he was waving and giving
the thumbs-up to indicate he was all right while he was dangling from
the parachute.
‘He’s
recovering at home. He broke the head of the humerus bone that sits in
the right shoulder. He’s got a rib and lung contusion and there is an
issue with his eyes because of the cold. It was around minus 60 degrees
up there.
‘It’s
a medical miracle he survived considering the temperature, the lack of
oxygen and the barotrauma [injury caused by a sudden change in
pressure].’ The pilot’s horrified wife, Traci, and children 12-year-old
Alexandra and Nick, nine, were standing with the family of Mike Alsbury
as the tragedy unfolded.
The
body of Alsbury, 39, was found still strapped into his seat on a desert
road by construction workers. His parachute did not deploy. His wife
Michelle said she had ‘lost the love of my life’.
Dr
Siebold said: ‘Mike’s children and my grandchildren were all watching
the flight so the emotional impact of that is tremendous.
‘Mike
was a friend and neighbour. Their children are the same age and
friends. Peter is asking himself whether he could have done more and why
he got out and Mike didn’t? Traci is a strong woman. She’s drained but
very much in charge.
‘She’s
protecting Peter and she’s holding up incredibly well most of the time.
He’s on pain medication, which is making him tired and confused.’
The plane separated mid-air, causing Alsbury, 39, to plummet to the earth while still strapped in his seat
Dr
Siebold, who split with Peter’s mother Barbara when his son was five,
spoke proudly of teaching his son to fly: ‘Flying was the only thing
Peter was ever really interested in. I flew privately – that was my
recreation – so he grew up with it. It’s what we did together. We would
go to the airport after school.’
At
16, Siebold studied aviation at California State University and landed a
job with Scaled Composites – the company conducting last week’s test
flight for Virgin Galactic – before he graduated.
‘He worked as an engineer and pilot, starting from the bottom and working his way up,’ Dr Siebold said proudly.
Siebold began working as a test pilot and engineer with Virgin Galactic at the start of its space programme a decade ago.
‘He
told me straight away he was involved with Virgin Galactic,’ his father
continued. ‘Safety was a great concern but I had total confidence in
his piloting skills.
‘Peter would say, “These airplanes fly just beautifully.”
‘He was never worried about the safety aspect of it.’
The
October 31 flight was so routine that Dr Siebold had no idea his son
was piloting the pioneering craft that day until his panicked
daughter-in-law phoned: ‘I picked up the phone oblivious to what had
happened. I said, “Hi Traci, how are you?” cheerful as usual and she
said, “It’s serious. Peter had an accident. We don’t know exactly but it
looks like he hurt his shoulder and he’s on his way to the hospital.”
‘We were worried but the main thing was we knew he was alive.
‘I
hope he’s going to recover enough to be able to fly again. That’s his
life. We’re focusing hour to hour rather than day to day.’
Yesterday,
it was revealed that 24 passengers who have paid £157,000 each for the
chance to go into space – alongside celebrities including Angelina Jolie
and Kate Winslet – have demanded their money back.
Virgin
Galactic chief executive George Whitesides claimed it was
‘unsurprising’ passengers had pulled out, adding: ‘I think what is
relevant is that the vast majority have said, “Don’t give up, keep
going, we’re with you.” ’
Before
the accident, billionaire Sir Richard Branson vowed he and son Sam
would become astronauts by the end of this year and the first space
tourist flights would begin next spring. But the Virgin Galactic project
has been beset by years of delays and safety fears, including previous
accidents with SpaceShipOne which necessitated a redesign of the ship’s
engines and fuel.
The
investigation into this month’s crash is now likely to delay any
commercial flight for at least another year. But Branson has vowed to
press ahead with the project, while acknowledging the risks taken by his
test pilots.
Last
night, Mr Whitesides paid tribute to Siebold, saying: ‘It will be
regarded as one of the most amazing test flight survival stories of all
time.’
Father's fury over rush to blame pilots for crash
Dr Klaus Siebold, Peter's father, criticised those who 'rushed' to blame human error for the crash
The father of the Virgin Galactic pilot who survived the crash has hit out at the ‘rush’ to blame human error.
Within
days of the tragedy, National Transportation and Safety Board (NTSB)
staff claimed co-pilot Michael Alsbury, who died, wrongly flicked a
safety switch controlling the rocket’s folding wings.
That
would cause them to deploy at an unsafe speed and ‘feather’ – slowing
down the rocket. But Dr Klaus Siebold, father of surviving pilot Peter
Siebold, claimed a second switch would have had to be deployed to cause
feathering.
Dr Siebold, himself a pilot and flight instructor, said: ‘Turning the safety lever won’t automatically feather the tail.
‘The fact that the tail was feathered without a pilot ordering it to do so suggests a mechanical problem, not pilot error.
‘It’s
really irresponsible for the NTSB to suggest a possible explanation for
the accident with months of investigation still to come.’
A
statement on the Virgin Galactic website says: ‘The NTSB indicated that
the lock/unlock lever was pulled prematurely based on recorded speed at
the time, and they have suggested that subsequent aerodynamic forces
then deployed the feathering mechanism, which resulted in the in-flight
separation of the wings and vehicle.’
