McBoyle v. United States

William McBoyle (defendant) was convicted of transporting a stolen airplane from Illinois to Oklahoma, knowing it had been stolen, in violation of the National Motor Vehicle Theft Act, and was sentenced to three years in prison plus a $2,000 fine. His conviction was affirmed on appeal, and the Supreme Court granted certiorari to decide whether an airplane counts as a 'vehicle' under the Act -- reversing the Tenth Circuit's contrary conclusion in the same prosecution.
