Developed by California-based next-generation aerospace company Advanced Tactics for the US Army (who else?), the Black Knight Transformer is a hybrid air and land vehicle—being a cross between a boxy truck and a multi-rotor helicopter—that can perform unmanned evacuations and cargo resupply missions.  It looks weird, granted, but it can supposedly fly up to a top speed of 240 km/h in the air. See it in action below.
