Largest Balloon Ever

bitpusherdotorg writes "The UK's Colin Prescot and Andy Elson are in the midst of preparations for their upcoming attempt at setting a new world balloon altitude record in July. The pilots will make their ascent in the largest helium balloon ever constructed, on an open flight deck (!) with nothing but a pair of tailor made Russian spacesuits to keep them breathing. Why pay 20 million for a shuttle when you can just balloon it?"
