Millions of dollars of military research has uncovered yet another valuable piece of information that I could of easily told them for a dollar just using my common sense. It's pretty obvious to me that anything with eyes will use that information it's getting to help judge the speed at which their going. In these tests their doing they have been able to control the speed at which a fruit fly flies by changing how fast the scenery beside it speeds by. It seems like fruit flies relies on their vision almost entirely for measuring the rate of speed their going. This information has been praised by the people backing it as being a very valuable find in helping with future military flying drones. I beg to differ, but maybe thats because I'm just one of those people that think it's ridiculous to pay millions and billions for common sense knowledge.
