Why, you may ask, don't conventional aircraft crush people and buildings as they travel above them? Well, aircraft are not really very heavy compared with the weight of the atmosphere. A 100-ton aircraft measuring 100 feet long by 10 feet wide needs to exert a downward force of less than a pound per square inch on the air below it to stay aloft. More important still is the fact that a plane's cruising altitude is high in relation to its size. As the airplane rises, the pressure it exerts on the atmosphere below spreads over a larger and larger region, so that it is significantly attenuated by the time it's transmitted to the ground.

The only way to get back to shore is to use propulsion. You could push yourself off a nearby rock very effectively. In this case, a lot of mass (the rock) moves away slowly when you push it, and you move away very fast. However, if you have to bring your own fuel with you, most people would not opt to carry a rock along for such a purpose. Instead, you might pack your backpack more lightly, with a golf club and golf balls. When you want to move on the ice, you unpack the balls, place them on the ice, and hit them away one at a time.

Be that as it may, what is the point of designing a spacecraft to perform right-angle turns and other such exotic aeronautics? 999 percent of the time will be spent in space.
