If Superman flew by you near the speed-of-light, he would look much shorter than if he flew by at the speed of an airplane. This is because length contraction (a concept in ETOSR) says when an object moves at high speeds, the object will look like it shrinks in length. Similar to time dilation, length contraction is only obvious at speeds close to the speed-of-light. If a limo could not fit into a garage when it is parked, do you think it would fit for a second if it travelled really fast (before it crashes through the wall of course)?
