>Japanese scientists and origami masters considered in 2008 launching a flotilla of paper planes from space.[2] The launch was tentatively slated for 2009[3] from the International Space Station[4] 250 miles above Earth. However, the planes' developers, Takuo Toda (see paper plane world records) and fellow enthusiast Shinji Suzuki, an aeronautical engineer and professor at Tokyo University, postponed the attempt after acknowledging it would be all but impossible to track the planes during their week-long journey to Earth, assuming any of them survived the searing descent. The developers continue, in 2009, with hopes that China or Russia will back further efforts on the project
>Some 30[4] to 100[5] planes had been considered to make the descent, each gliding downward over what was expected to be the course of a week to several months. If one of the planes survived to Earth, it would have made the longest flight ever by a paper plane, traversing the 250 mi./400 km. vertical descent. In a test in Japan in February 2008, a prototype about 2.8 inches long and 2 inches wide survived Mach 7 speeds and temperatures reported to be 200°C in a hypersonic wind tunnel for 10 seconds. Materials designed for use in conventional reentry vehicles, including ceramic composites, withstand temperatures on the order of 2200°C.[6] The 30 cm planes were to have been made from heat-resistant paper treated with silicon.
