I bet you've never asked this question before. Would a paper airplane burn up on re-entering Earth's atmosphere? It's actually a serious suggestion because sending heavy objects sledding back through flames to our blue world is the sort of high risk, high reward ride that could benefit from a conceptual overhaul. MSNBC:
'Paper planes are extremely light so they slowdown when the air is thin and can gradually descend,' said Shinji Suzuki, a professor of aerospace engineering [at the University of Tokyo].
Suzuki said the technology might one day be used for unmanned spacecraft.
The team has asked a Japanese astronaut to release... 8-inch planes, made from paper chemically treated to resist heat and water, from the space station.
Will they reach Earth? Who knows? But if they do, it will likely take some time - like several months.
