Around the world in a Balloon In order to establish the record for around-the-world balloon flight, balloonists could neither touch down nor refuel in flight for the duration of the journey. Who were the first two men to successfully meet the requirements for circumnavigating the globe in a balloon? On what date did they complete their journey? How long did it take?
The jet stream was discovered during World War II when aviators first tried to cross the Pacific Ocean. Describe some characteristics of the jet stream. Why is it important to global balloonists?
The cabin of the Breitling Orbiter 3 was designed to provide comfort in the extreme cold and low atmospheric pressure conditions found at high altitudes, while being as small and lightweight as possible. What pieces of equipment which enhanced the pilots' comfort were in the cabin?
An array of specialized equipment was included on the Breitling Orbiter 3. Describe the types of communication equipment available. What equipment was specifically designed to enhance the safety of the pilots?
Describe some aspects of the daily life of the pilots during the flight of the Breitling Orbiter 3. Include aspects like food, clothing, rest and work times, and conditions inside the cabin in your description. Questions: The first men who circumnavigated the world were Bertrand Piccard and Brian Jones. They completed their journey on Sunday, March 21, 1999 They needed 20 days to circumnavigate the world. A narrow, variable band of very strong, predominantly westerly air currents encircling the globe several miles above the earth. A lot of balloonists are trying to catch a ride on the jet stream, which will carry the balloons around the Earth. Therefore, for global balloonists, troughs and ridges present the least desirable air flow pattern. Food:
the only had pre-packed or instant food.
The cooking facilities were very basic - just the ability to heat water.
They also had fresh food pre-cooked and sealed in poly bags which they could reheat in hot water (this lasted the first 3 days).
For the first days they had some fresh fruit too. Clothing:
The pilots were wearing insulating synthetic fibre clothes to keep themselves warm enough Work Times:
They had planned to alternate six-hour shifts at the controls. inside of the cabin the cabin During the flight the cabin atmosphere was supplemented by nitrogen and oxygen; the carbon dioxide was removed by lithium hydroxide filters. Cabin pressure was maintained at around 3.5 psi by adding oxygen and nitrogen to the cabin air, as necessary. MAIN FEATURES:
1: Helium tent balloon
2: Insulating tent
3: Helium valves
4: Chimney rip
5: External insulating layer
6: Helium cell
7: Hot air cone
8: Appendix
9: Tear-out skirt
10: Fireproofed layer Fax Machines and Sattelite phones. Breitling Orbiter 3 March 1st 1999; 22:03:
Its colder than we expected, but the
synthetic clothes that we have brought are doing a good job of keeping us warm. The temperature is about 15 degrees celsius
in the cabin.This week is the only week where we are allowed fresh food. Its
not the best food Ive ever had but I am still savouring it, for it is the last
time we will be having fresh food for a very long time....Jones took
the first shift of piloting while I rested. After 6 hours he woke me and we switched, I was nervous but there were no weather troubles. Day 1 Day 3 March 2nd 1999; 21:56:
Today the weather conditions are still pretty good and we didn't experience any compications so far.
The temperature in the cabin is still 15°C , same as yesterday, while outside it's -23.4°C.
Since last night at 3:36 a.m. we are on the jetstream which lets us move on faster.
Today, we are glad that we still have fresh food.
Bertrand is pretty tired already and feels a bit sick. He says it's just a cold so it's not too bad but I took over 2 1/2 hours of his shift so he can rest and get better. Now it's his turn and we hope we won't get into turmoils. March 3rd 1999; 19:48:
Last night there was a storm coming up so we had to change the route about 3 miles off the usual course. Because of that we lost about an hour but since we're back on the jetstream again we can catch it up. Now, the weather conditions are okay and we can move on.
Today is the last day we can have fresh food so we enjoy the last bites of it because then we have to switch to instant food.
The temperature in the cabin also sank to 10.4°C so we had to fully rely on our synthetic clothes which still keep us warm but we hope it's not getting any colder. The temperature outside is -21.7°C and when we are not at the machines, we rest or we read. It's starting to get lonely in here even though I have Piccard with me who keeps me company - which I'm really glad of. Day 2
