Paper Planes Launched from the Edge of Space

What's the difference between a paper plane and a paper space plane? Altitude! About 125,000 feet to be precise:

The balloon, filled with helium gas and carrying a load of paper planes, took 2.6 hours to rise to 37,339 metres (that's at the edge of space!), where it burst and took only 40 minutes to fall back to earth. It landed in a forest just south east of Berlin, where our team had to use a very long pole to retrieve the payload from the top of a tree. 

The hand-crafted paper planes with their precious cargo of Samsung SD memory cards were released at around 36,3500 metres and could land anywhere.
