These folks were hired by Samsung to launch 200 paper planes containing memory cards from a weather balloon sent over Germany. Anyone who finds one of these planes is asked to visit the Project Space Planes website and make a note of it.
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.
