Abstract: A transportation system includes a vehicle having wings, a propulsion system, a lifting gear coupling the vehicle to an undercarriage, and a guidance assembly movably connecting the undercarriage to guide rails. The wings generate aerodynamic lift when the vehicle exceeds a first speed. The lifting gear supports a load of the vehicle in a first position in relation to the undercarriage when the vehicle travels at less than the first speed, allows the vehicle to lift to a second position in relation to the undercarriage as the vehicle accelerates beyond the first speed, and maintains the vehicle in the second position when the vehicle exceeds the first speed. The guidance assembly shiftingly engages the guide rails through rollers that are in rolling contact with the guide rails when the vehicle is in the first position and are displaced from the guide rails when the vehicle is in the second position.

Abstract: A game apparatus includes a projectile made of resilient foam material which is in the shape of an enlarged "jack" and a plurality of bats having soft impact areas which are used to strike the projectile so as to move the projectile between a pair of goal posts which are also preferably resilient. Generally, the game apparatus is used to play a game which resembles field hockey, but may be played indoors or in a relatively confined outdoor area. By utilizing relatively "soft" bats and a relatively soft projectile, the chance of injury is reduced. Since the projectile has the shape of a "jack" it will often follow an irregular trajectory and will not roll far after hitting the ground.
