Considered by many as one of the worst aircraft designs of all time, the “strut-less, wings like a bird” Christmas Bullet had (surprise!) an annoying habit of shedding those unsupported wings immediately after takeoff. Two were built, both lost their visible means of support. Note: Dr. William Christmas designed the aircraft with an idea in mind that it could be used to fly over to Germany and kidnap Kaiser Wilhelm II during WW1. No, I did not make that up.
