Apparently I’m the last one to hear about this since I was the 3166th Digg, but Andy Woerner and a group of friends have built a working X-wing fighter powered by solid-fuel rocket engines.  This bad boy is 21 feet long and complete with a model R2D2.  It was set to launch yesterday.  The results were about what you’d expect.  I don’t think R2 managed to eject though, poor little droid.
