Jetpacks were always the things in movies that were part of what the future world would look like -- people would be traveling by flying themselves. Well, now it's a reality.
There are a lot of unanswered questions in the world, one of which is why geese and other migrating birds fly in a 'v' formation. And come to think of it, I've never even questioned why they do until right now. Good thing I did some research to share with everyone!
