Fell off the roof? No.
Dragged off is more like it.
My kite has an eight foot wingspan and two lines.
Each one is 100 pound test line.
When the wind gets going, it has picked me up off the ground, and drug me face down across the park.
I can cut perfect sqaures in the sky, or have it come straight down, turn 90degrees before hitting, and then zoom straight and level across the field, turn 90 and go straight backup. And you do not want to be in the way of these things.
