And, I mean, first of all we -- nobody had actually crossed the Atlantic in a hot air balloon before, so we had to build a hot air balloon that was capable of flying in the jet stream, and we weren't quite sure, when a balloon actually got into the jet stream, whether it would actually survive the 200, 220 miles an hour winds that you can find up there.
Og for det første -- ingen havde krydset Atlanterhavet  i en luftballon før, så vi måtte bygge en varmluftballon  der kunne flyve i jetstrømmen, og vi var ikke sikre på, om en ballon i jetstrømmen, kunne klare vinde på  320 til 350 km i timen
