noise pollution from private planes

I live in a relatively quiet city, until recently. A flight school
opened up across the bay from me, and all day long, all I can hear
outside are these private plane motor noises.

It is really awful. It is like having a gas powered lawn mover
above me all day long. As one plane leaves, another one takes
its place. I am grateful when the evening comes, or for a rainy
day, so I wont hear them anymore.

Let's get some noise control on these small planes before we all go
crazy.
