She's earned a hefty fine and at least a license suspension, but to claim that a J-3 can "wipe out several homes" is an exaggeration.
I learned to fly in one. The airplane has an empty weight of less than 700 lbs, flies at about 65 mph, and lands slightly above 40 mph fully loaded. With only my skinny 150 lb. butt in it landing into a 10 mph wind I landed at about 25 mph ground speed and could have it stopped in less than 50 yards. The reason it was and is highly regarded as a trainer is that it requires true "stick 'n rudder" skills to fly, but does it so slowly that there is plenty of time to make mistakes and recover from them, and you have to work at being stupid to hurt yourself or anyone else with it.
