Technically you cannot touch anything.That’s because your atom’s electrons repelobjects when they are 10^-8 metres away. Sotwo electrons never can touch each other dueto the repulsion between them. The atomsof your body cannot touch any objects dueto this repulsion. You just feel the force ofresistance. So right now you are just hoveringover objects.

In the mid-twentieth century, aerospace engineering made great strides in aircraft technology. That is, the aircraft was redesigned, including increased safety so that it could carry more passengers and go faster. Until the 1950s, aircraft windows were square. When commercial aviation began, airlines began flying at higher altitudes to save aviation fuel. (Normal passenger planes…
