Oh, National Geographic—what will you think of next? As the rest of us were downing greasy brunch food this weekend, these guys—scientists, engineers, and two balloon pilots—woke up at dawn to set free a real-life version of the house from Pixar’s hit film Up on a private airfield outside L.A. Measuring 16 feet by 16 feet and 18 feet high, the yellow house was buoyed by 300 8′ weather balloons—a total height of more than 10 stories—setting a new world record for the “largest balloon cluster flight ever attempted.” It reached an altitude of 10,000 feet and flew for an hour. An experiment launched by National Geographic, this house was equipped with several large balloons to simulate the flying house in Up. This experiment was conducted outside of Los Angeles. Take a look. Enjoy.
