GENEVA (Reuters) - A Swiss-British ballooning duo floated over the Pacific on Monday, waiting to hear if they had set a new distance record in their round-the-world attempt. The team‘s control centre in Geneva said Bertrand Piccard of Switzerland and Briton Brian Jones had travelled just over 25,000 kilometres since setting off from the Swiss Alps two weeks ago. Unofficially, that beats the previous best set by American Steve Fossett early last year of 22,910 kms. But a team spokeswoman said the International Aeronautical Federation (FAI), which verifies world records in air sports, had its own method of distance calculation, which differed quite significantly from a team‘s own. The team would now have to wait to see whether the Breitling Orbiter 3 craft had travelled far enough by the FAI‘s reckoning. On Monday morning, Piccard and Jones were travelling at a speed of around 118 kilometres an hour and an altitude of 10,000 metres, located south of Hawaii and aiming for Mexico. "There are no problems. Everything‘s going according to plan," the spokeswoman said. Late on Monday, the pair aim to catch a high-speed sub-tropical jet stream which will sweep them on across Mexico and out into the Caribbean between Jamaica and Cuba. From there, they plan to hitch onto a North Atlantic air flow which should bring them back to Africa, if all goes well, for a touchdown in Morocco next Saturday or Sunday.
