A car takes off from private land at 14 feet off the ground using thrusters and flies over the highway, and fires accelerator thrusters, making it go forward at approximately 300 miles an hour, for one mile.
Were any laws broken?
MCL 259.2 (e) defines an aircraft as follows:
(e) “Aircraft” means any contrivance used or designed for navigation of or flight in the air.
MCL 259.9 (d):
(d) “Vehicle” means any device in, upon, or by which a person or property is or may be transported, except an aircraft.
They do not define flight, and do not state altitude at which one would be considered flying rather than hovering. If the car was a stock car, save for the minimal addition of some sort of thrust producing device to render it airborne, would it be considered an aircraft? Consider the legal status of a hovercraft.
and last but not least: Article I, Section 8, Clause 3 of the United States Constitution
And of course, it is understood that your answers are not legal advice, whether or not you are a lawyer.
