They are the fathers of the flight. da vinchi is the grandfather. he did not put hs name on his invention so it was okay for the wright brothers to take it, it was also good thing they did b/c now we have planes that FLY, all because of the fathers of flight. their manes are Orville, and Wilbur (oink, oink)really everyone coppied off or them like northwest airlines, spirit and fly jamiaca etc. They are the fathers or flight.
