Admit it, you've watched the movie "Up" and wondered -- could you really attach enough helium balloons to a house to make it fly? Well now there's an answer --- yes - sort of. The National Geographic Channel has documented an attempt to do exactly that for its new series "How Hard Can It Be?"
The average house with contents weighs more than 2,000 pounds, but nonetheless, last week a team of scientists, engineers and two world-class balloon pilots successfully launched the house into the sky by attaching 300 weather balloons filled with helium.
The flight set a new world record for the largest balloon cluster flight ever attempted. The entire experimental aircraft was more than 10 stories high and reached an altitude of more than 3,000 meters. It flew for approximately one hour.
