I've come to the conclusion that radar might be the most important invention of all time. Modern ships and aircraft would never be able to function without it. We'd constantly had planes crashing into each other. Radar also gives us a way to warn people when there is a storm coming through so they can get out of the way. This prevents boats from being caught in storms and it prevents people from being killed by tornadoes.
