Some of the appeal of TERREPLANE would diminish if the vehicles had large wings; however, the vehicles will not have prominent wings. They will have "flaps" that are used for control and fine tuning of lift, but TERREPLANE vehicles will not have obvious wings.

The below table summarizes example TERREPLANE vehicles including the two benchmark cases of the Wright Brothers first aircraft and a Cessna 150. The wingspan of the Cessna 150 is 33 feet, and simple calculations will illustrate how the "prominent" wing aspect of this vehicle disappears as the weight of the vehicle decreases and the velocities increase. The assumptions are that life (including impact momentum) are proportional to the velocity squared and that the body of the vehicle contributes to 20% of the lift.

By reducing the weight of the vehicle by 50% through removing the engine and fuel, the needed wingspan is decreased from 33 feet to 14 feet. A doubling of the velocity would further decrease the needed lift to 25% of the lift for the 63 mph takeoff velocity with a wing span of 3.7 feet. Hence, at 90 mph, a 2-seater TERREPLANE vehicle would not need obvious wings.

The back-of-the-envelope calculations are just the starting point for what is possible. Great things are indeed possible. In many applications it would be "cost optimal" to allow the Propulsion Line to support part of the vehicle weight during travel.

This is the starting point. Optimal pressures in Vactunnels, optimal fractions of the weight to be supported by the Propulsion Line, and novel approaches to create lift lead to an entire new technology specialty with years of great work to be performed.
