Helicopters have become one of the worlds more likely vehicle. They are really usefull and helpfull. This flying inventions can take you up in the air andd let you see stuff that you really wouldn't normally be able to see, or just to give you a better look. Personally, I'm a really big fan of helicopters they are just interesting. The first helicopter was called a Helical Air Screw invented in 1490 By Leonardo Da Vinci. It wasn't really a helicopter it was more like a spiral design creation. It's preety interesting how something like that has changed so much. Who knows what the future may hold?
