Yes – he made it! Every teenage boy understands the meaning of
a calculated risk. This adventure went
well beyond any such calculation. All that
could be done was to ensure all the physics available was more or less on your
side when a glitch occurred. You try not
to do this twice.
This is actually quite an
achievement and was always challenging to the point of inherent possibility. We now know it can be done safely enough to
survive at least once. The actual
probability of success was certainly below one in ten, but good enough to
expect a success.
Bravo!
Austrian daredevil breaks sound barrier with record skydive

Austrian daredevil Felix Baumgartner became the first man to break the
sound barrier in a record-shattering freefall jump from the edge of space
Sunday, organizers said.
The 43-year-old jumped from a capsule more than 39 kilometers above the
Earth, reaching a speed of 1,136 kilometres per hour before opening his red and
white parachute and floating down to the New Mexico desert.
“I think 20 tonnes have fallen from my shoulders. I prepared for this
for seven years,” Mr. Baumgartner told German-language ServusTV in Austria ,
in his first interview after the leap.
Referring to a helmet problem that nearly forced him to abort at the last
minute, Mr. Baumgartner said: “Even on a day like this when you start so well,
then there’s a little glitch.
”And you think you’ll have to abort -- what if you’ve prepared
everything and it fails on a visor problem. But I finally decided to jump. And
it was the right decision.“
Shortly before jumping, in footage beamed live around the world -- on a
crackly radio link recalling Neil Armstrong’s first words on the Moon -- he had
said: ”Sometimes you have [go] up really high to [realize] how small you are.“
The Austrian took more than two hours to get up to the jump altitude.
Mr. Baumgartner had already broken one record, before he even jumped: the
previous highest altitude for a manned balloon flight was 34,667 metres, set in
1961.
Mr. Baumgartner had been due to jump from 36,576 metres, but the
balloon went higher than expected, to more than 38 kilometres.
One of the first people to congratulate him was Austrian President
Heinz Fischer.
”I warmly congratulate Felix Baumgartner on this great success, which
was achieved with courage and perseverance and is finding worldwide attention. Austria
is proud of your accomplishment,“ he wrote on his Facebook page.
The Red Bull Stratos mission was the second attempt for the skydiver
after an initial bid Tuesday was aborted at the last minute due to winds.
The biggest risk Baumgartner faced was spinning out of control, which
could have exerted g-force and made him lose consciousness. A controlled dive
from the capsule was essential, putting him in a head-down position to increase
speed.
More gruesomely, the skydiver’s blood could have boiled if there were
the slightest tear or crack in his pressurized spacesuit-like outfit, due to
instant depressurization at the extreme altitude.
Temperatures of -68C could also have had unpredictable consequences if
his suit somehow failed.
The leap went off flawlessly, though there was a minor problem as the
capsule ascended: a heater failed on Mr. Baumgartner’s helmet faceplate,
meaning it was becoming fogged up when he exhaled.
After considering the options, Mr. Baumgartner and his entourage
decided to go ahead with the jump.
Mr. Baumgartner’s 100-strong backup team includes retired U.S.
Air Force colonel Joe Kittinger, who had held one of the records the Austrian
was trying to break: the highest freefall jump, which Mr. Kittinger made from
31,333 metres in 1960.
”Let the guardian angel take care of you,“ Mr. Kittinger told Mr.
Baumgartner shortly before he jumped into the void.
The giant balloon -- which holds 859,000 cubic meters of helium -- is
needed to carry the Red Bull Stratos capsule of nearly 1.3 tons to the
stratosphere.
It is made of near transparent polyethylene strips even thinner than a
dry cleaner bag, which are heat-sealed together. Very thin material is
necessary to save weight.
The skydiver has been training for five years for the jump. He holds
several previous records, notably with spectacular BASE jumps from the Petronas Towers
in Kuala Lumpur and the Christ the Redeemer
statue in Rio de Janeiro , Brazil .
Speaking before the launch, Mr. Baumgartner said he would be proud to
be the first person to break the speed of sound in freefall.
”But really, I know that part of this entire experience will help make
the next pressure suit safer for space tourists and aviators,“ the jumper said.
His launch coincided with the 65th anniversary of American pilot Chuck
Yeager breaking the speed of sound.
