8cm Tiny Fiery Instruments of Death

It appears that in the near future certain groups in Japan hope to launch a paper (probably not paper... definitely something stronger and less... flammable...) airplane from the ISS to Earth.

Here is the original Japanese if you can read it.

Here's what, as far as I can tell, is the first English post on the topic.

This seems interesting.. and I am very VERY interested in hearing about a paper plane that can withstand Mach 1 intact, let alone Mach 20... Also, What about the speed this things going to build up on reentry? If it hits a building? "Paper plane devastates Down-Town New York City" would make a catchy and humorous title, more fitting of the Onion than the New York Times.
