I hate ultralights. At least the people that fly them. Every single one of them I've met fly like the idiots I encounter on the road. I know there or the very few who actually know what they are doing, where not to go, and have some concept of the physics of flight.
I dont mind when REAL planes buzz my house or jets for that matter. But since I've seen how these "sport pilots" fly It make me nervous having more idiots on the ground up in the air. Most of them dont have radios, and those that dont know the rules, for instance fly perpendicualar around 100 feet right over an approach runway at Quad City wich is class C airspace! Flychicaga might be able to back me up on that.
Sorry if I sound so negetive about it but I have had to many close calls with these guys being in places they shouldn't be.
