Boeing and other big names in aviation (along with DARPA) will lend their mentorship and technical expertise to the teams over the course of the contest. Winning is simple: The device/vehicle must carry a person 20 miles without refueling or recharging with vertical (or nearly vertical) take-off and landing. Teams will get technical guidelines -- the competition is seeking a solution anyone can use that is ultra-compact, quiet and "urban-compatible" -- but how they design or engineer their "personal flying device" is up to them.

Competition prize money will be doled out in three phases: Ten teams with interesting written concepts will be given $20,000 prizes, then four $50,000 will be handed out for the best prototypes and revised technical specifications, before a winner at the "final fly-off" takes home $1 million. Even if they don't win, teams may qualify for supplementary prizes at the last event, including $100,000 for "disruptive advancement" of state-of-the-art aviation tech, $250,000 for quietest entry and $250,000 for the smallest.

Teams can register for the first phase of competition now on the GoFly Prize site until April 4th, 2018. After that, teams must register for Phase II by December 8th, 2018.

Update: This post has been updated to clarify that the content puts not stipulations on the design of the "personal flying device." It could be a jetpack, a single-seat flying taxi or something else entirely -- we'll have to wait and see what designs are produced.
