Virgin Galactic spaceship test flight ends in fatal crash, one pilot killed

November 1, 2014

Mojave/California, Nov 1: A suborbital passenger spaceship being developed by Richard Branson's Virgin Galactic company crashed during a test flight on Friday near the Mojave Air and Space Port in California, killing one pilot and seriously injuring the other, officials said.

Virgin GalacticThe crash of the vehicle, undergoing its first powered test flight since January over the Mojave Desert, 95 miles (150km) north of Los Angeles, came days after another private space company, Orbital Sciences Corp, lost a rocket in an explosion moments after liftoff in Virginia.

The back-to-back accidents dealt a considerable blow to the fledgling commercial space launch industry, which has been taking on more work traditionally done by the US government while expanding for-profit space markets, including tourism.

Television footage of the Virgin Galactic crash site showed wreckage of the spacecraft lying in two large pieces on the ground, and the company said the spacecraft was destroyed. Kern County Sheriff Donny Youngblood said a debris field was spread over more than a mile.

One spaceship pilot was killed in the crash and his body was found in the wreckage, while the second pilot, who ejected and parachuted to the ground, survived with serious injuries, Kern County Sheriff Donny Youngblood said. The survivor was found more than a mile from the main wreckage site, he said.

Both crew members were test pilots for Scaled Composites, the Northrop Gruman Corp subsidiary that designed and built the spacecraft for Virgin and lost three other employees in a July 2007 ground test accident during development of the ship's propulsion system.

Friday's crash occurred shortly after the craft, dubbed SpaceShipTwo, separated from the jet airplane that carried it aloft for its high-altitude launch, according to the Federal Aviation Administration.

Scaled Composites President Kevin Mickey told a news conference the ill-fated flight was the first using a new rocket fuel formula the company switched to in May. He said that formula "had been proven and tested on the ground" before Friday's test launch.

Stuart Witt, chief executive of the space port, said officials were not ready to "speculate on the cause" of the crash.

The National Transportation Safety Board said it was sending one of its "go-teams" to investigate the accident.

Branson said via Twitter that he was on his way to Mojave following the crash. "Thoughts with all @virgingalactic & Scaled," he tweeted.

George Whitesides, chief executive of Virgin Galactic, said he expected Branson to arrive by Saturday morning.

"Space is hard, and today was a tough day. We are going to be supporting the investigation as we figure out what happened today, and we're going to get through it," he told a news conference at the space port.

He added: "We believe we owe it to the folks who were flying these vehicles as well as the folks who have been working so hard on them, to understand this and to move forward, which is what we'll do."

Paying customers must wait

More than 800 people have paid or put down deposits to eventually fly aboard the spaceship, which is hauled to an altitude of about 45,000 feet (13.7kms) and released by Virgin's White Knight Two carrier jet airplane. According to plans, the spaceship then fires its rocket motor to catapult it to about 62 miles (100km) above Earth, giving passengers a view of the planet set against the blackness of space and a few minutes of weightlessness.

The vehicle is based on a prototype, SpaceShipOne, which 10 years ago won the $10 million Ansari X Prize for becoming the first privately developed manned spacecraft to fly in space.

"During the test, the vehicle suffered a serious anomaly resulting in the loss of SpaceShipTwo," Virgin said in a statement just after the crash, adding: "We will work closely with relevant authorities to determine the cause of this accident and provide updates ASAP."

Witt said the first sign of a malfunction came 90 seconds to two minutes after the carrier jet released the spacecraft, which occurred at 10:10am local time.

"There's usually a certain cadence, and you see things occurring, and the thing makes a contrail and the like. Because of the very light cirrus clouds, I was eyes on, but I didn't see any anomaly. In fact it was when I wasn't hearing anything that I became concerned. And I looked over at my colleague, and then there was a radio call, something about a chute."

The crash was the second accident this week involving a commercial US space company. On Tuesday, an Antares rocket built and launched by Orbital Sciences exploded 15 seconds after liftoff from Wallops Island, Virginia, destroying a cargo ship bound for the International Space Station.

Friday's crash marked a major setback for Virgin Galactic, a US offshoot of billionaire Branson's London-based Virgin Group. The company was aiming to make the world's first commercial suborbital space flights with SpaceShipTwo, a six-passenger, two-pilot spacecraft.

The launch was to have been the first in a series of test flights leading up to Virgin Galactic's maiden flight beyond Earth's atmosphere.

Virgin ultimately was planning to add four more suborbital spacecraft to its fleet, along with a second White Knight carrier jet. Plans call for the fleet to fly out of a new commercial space port in Las Cruces, New Mexico, once the company completes all test flights and is certified for passenger service to begin.

Virgin Galactic's Whitesides told a Toronto space conference earlier this month that a second spacecraft was already under construction and about 60 percent complete.

Other companies developing passenger suborbital spacecraft include privately owned XCOR Aerospace, which is building a two-person space plane called Lynx, and Blue Origin, a startup space company owned by Amazon.com Inc founder Jeff Bezos.

Virgin Galactic also plans to use its White Knight Two carrier jets to launch small satellites and payloads into orbit.

Washington, Jul 17: US President Donald Trump's economic adviser Larry Kudlow has said that TikTok may cut off ties to its Chinese parent and become a 100 per cent American company to circumvent demands to ban it as India has done.

"I think TikTok is going to pull out of the holding company which is China-run and operate as an independent American company," he told reporters at the White House on Thursday.

The US has not made a final decision on whether to ban it - which has been suggested by Secretary of State Mike Pompeo, he said.

TikTok being divested by ByteDance Technology Company "is a much better solution than banning or pushing away", said Kudlow, who is the Director of the National Economic Council.

He said that its services will be located in the US and "it will become an hundred per cent American company".

If it becomes a US company without Chinese links, India may have to reconsider the ban on the short video app wildly popular in the country.

India banned TikTok along with 58 other Chinese apps on June 29 citing threats to its defence and national security.

The ban came after a deadly clash between Indian and Chinese troops along the Line of Actual Control in Ladakh.

Under Beijing's National Security Law, all Chinese companies have to provide intelligence requested by the government, creating risks for users and their countries.

India was TikTok's biggest market outside of China, where it operates as Douyin.

There were about 200 million users in India and over 300 million downloads.

The US comes next with over 30 million users for the app.

Washington, Jul 2: Former US Ambassador to the UN, Nikki Haley, on Wednesday (local time) hailed India's action to ban 59 apps linked to Chinese firms including Tik Tok and said New Delhi is continuing to show it will not back down from China's aggression.

"Good to see India banning 59 popular apps owned by Chinese firms, including TikTok, which counts India as one of its largest markets. India is continuing to show it won't back down from China's aggression," Haley tweeted.

The Indian government on Monday announced that it had decided to block 59 apps in view of the information available that "they are engaged in activities which are prejudicial to sovereignty and integrity of India, defence of India, the security of the state and public order".

Information Technology Minister, Ravi Shankar Prasad said that the government has banned the apps for the safety, security, defense, sovereignty, and integrity of India.

Haley'='s remarks come after US Secretary of State Mike Pompeo welcomed India''s ban on the Chinese apps and stressed that the move would "boost India''s integrity and national security".

"We welcome India''s ban on certain mobile apps. India''s clean app approach will boost India's sovereignty and boost integrity and national security," Pompeo said.

Washington, Apr 28: After nearly three weeks in an intensive care unit in Los Angeles, doctors treating 41-year-old Broadway actor Nick Cordero for COVID-19 were forced to amputate his right leg.

The flow of blood had been impeded by a blood clot: yet another dangerous complication of the disease that has been bubbling up in frontline reports from China, Europe and the United States.

To be sure, so-called "thrombotic events" occur for a variety of reasons among intensive care patients, but the rates among COVID-19 patients are far higher than would be otherwise expected.

"I have had 40-year-olds in my ICU who have clots in their fingers that look like they'll lose the finger, but there's no other reason to lose the finger than the virus," Shari Brosnahan, a critical care doctor at NYU Langone said.

One of these patients is suffering from a lack of blood flow to both feet and both hands, and she predicts an amputation may be necessary, or the blood vessels may get so damaged that an extremity could drop off by itself.

Blood clots aren't just dangerous for our limbs, but can make their way to the lungs, heart or brain, where they may cause lethal pulmonary embolisms, heart attacks, and strokes.

A recent paper from the Netherlands in the journal Thrombosis Research found that 31 percent of 184 patients suffered thrombotic complications, a figure that the researchers called "remarkably high" -- even if extreme consequences like amputation are rare.

Behnood Bikdeli, a doctor at New York-Presbyterian Hospital, assembled an international consortium of experts to study the issue. Their findings were published in the Journal of The American College of Cardiology.

The experts found the risks were so great that COVID-19 patients "may need to receive blood thinners, preventively, prophylactically," even before imaging tests are ordered, said Bikdeli.

What exactly is causing it? The reasons aren't fully understood, but he offered several possible explanations.

People with severe forms of COVID-19 often have underlying medical conditions like heart or lung disease -- which are themselves linked to higher rates of clotting.

Next, being in intensive care makes a person likelier to develop a clot because they are staying still for so long. That's why for example people are encouraged to stretch and move around on long haul flights.

It's also now clear the COVID-19 illness is associated with an abnormal immune reaction called "cytokine storm" -- and some research has indicated this too is linked to higher rates of clotting.

There could also be something about the virus itself that is causing coagulation, which has some precedent in other viral illnesses.

A paper in the journal The Lancet last week showed that the virus can infect the inner cell layer of organs and of blood vessels, called the endothelium. This, in theory, could interfere with the clotting process.

According to Brosnahan, while thinners like Heparin are effective in some patients, they don't work for all patients because the clots are at times too small.

"There are too many microclots," she said. "We're not sure exactly where they are."

Autopsies have in fact shown some people's lungs filled with hundreds of microclots.

The arrival of a new mystery however helps solve a slightly older one.

Cecilia Mirant-Borde, an intensive care doctor at a military veterans hospital in Manhattan, told AFP that lungs filled with microclots helped explain why ventilators work poorly for patients with low blood oxygen.

Earlier in the pandemic doctors were treating these patients according to protocols developed for acute respiratory distress syndrome, sometimes known as "wet lung."

But in some cases, "it's not because the lungs are occupied with water" -- rather, it's that the microclotting is blocking circulation and blood is leaving the lungs with less oxygen than it should.

It has just been a little under five months since the virus emerged in Wuhan, China, and researchers are learning more about its impact every day.

"While we react surprised, we shouldn't be as surprised as we were. Viruses tend to do weird things," said Brosnahan.

While the dizzying array of complications may seem daunting, "it's possible there'll be one or a couple of unifying mechanisms that describe how this damage happens," she said.

"It's possible it's all the same thing, and that there'll be the same solution."
