| Why Baumgartner's record dive almost didn't happen | |
| (about 5 hours later) | |
| Austrian Felix Baumgartner is the first skydiver to go faster than the speed of sound - but a severe claustrophobic reaction to the pressure suit he had to wear during his ascent to 39km (24 miles) and his freefall almost put the whole project in jeopardy. | |
| The 43-year-old adventurer had never worked at extreme altitude before, and in order to survive the jump he needed to be more than a skydiver - he needed to become a test pilot. | The 43-year-old adventurer had never worked at extreme altitude before, and in order to survive the jump he needed to be more than a skydiver - he needed to become a test pilot. |

| Retired US Air Force Col Joe Kittinger, who previously held the record for the highest freefall, acted as Baumgartner's radio link in mission control at Roswell airport, and understood the risks of the dive better than anyone else. | |
| "The vacuum, the nothingness, it's waiting there to kill you immediately. It's hostile up there, there's no pressure, it's cold, there's the glare. If something breaks, that's it," he said. | "The vacuum, the nothingness, it's waiting there to kill you immediately. It's hostile up there, there's no pressure, it's cold, there's the glare.

| The mission was funded by Red Bull - but the money came at a price - a 12 month deadline which the scientists were not used to. And for Baumgartner there were many things which he felt he had no control over. "I have to trust these scientists. If something goes wrong you're all by yourself and that is really scary." | The mission was funded by Red Bull - but the money came at a price - a 12 month deadline which the scientists were not used to.

| His survival relied on one piece of technology above all others - his pressurised suit. Even experienced astronauts struggle with the suit and he had to learn to skydive in it. | |
| One of the team's biggest fears was that Baumgartner's suit would fail above the Armstrong limit - the altitude that produces an atmospheric pressure so low (0.0618 atmosphere) that water boils at the normal temperature of the human body. | One of the team's biggest fears was that Baumgartner's suit would fail above the Armstrong limit - the altitude that produces an atmospheric pressure so low (0.0618 atmosphere) that water boils at the normal temperature of the human body. |
| "You don't have the pressure of the atmosphere holding the gases in your bloodstream - so your body starts releasing all the gas. Out of every orifice you have you'll start to ooze fluids. It's like the worst possible horror film," said Art Thompson, the project team principal. | "You don't have the pressure of the atmosphere holding the gases in your bloodstream - so your body starts releasing all the gas.

| Baumgartner's hand-sewn pressure suit cost more than one million pounds and is capable of keeping him alive on the moon. It took a team of 30 people six months to make. | Baumgartner's hand-sewn pressure suit cost more than one million pounds and is capable of keeping him alive on the moon.

| Part of his training focussed on acclimatising him to the suit, so he would feel as comfortable in it as in his own clothes - but it severely restricted his movements. | Part of his training focussed on acclimatising him to the suit, so he would feel as comfortable in it as in his own clothes - but it severely restricted his movements. |
| "It's hard to describe how it feels, your movements are totally limited. You can't breathe that easily. It's difficult - you don't feel a damn thing in that suit," he said. | "It's hard to describe how it feels, your movements are totally limited. You can't breathe that easily.

| As Baumgartner went through his last-minute checks inside the capsule, it was found that a heater for his visor was not working. This meant the visor fogged up as he exhaled. | As Baumgartner went through his last-minute checks inside the capsule, it was found that a heater for his visor was not working.
