I live near the airport and yes the skydivers go up a lot, and we like to watch them come down.
But I would have to ask is it possible to quiet down that plane? Maybe it is like having a Harley with straight pipes. It could be that the pilot has Harley envy.
Anyway, the plane they use, once a year, that holds 18 jumpers is nice and quiet. The one that holds six jumpers, not so much.
