I agree with the 7-8 minutes that Curt mentions as being required for a pl=
ane to pass. And they sure can add up and overlap near where I live.
I often have better luck recording fairly near an airport (Delta hub in Cin=
cinnati) because they schedule flights to all arrive at about the same time=
and leave a while later. So there's a window of pretty decent quiet (7:30=
-7:50 AM for example).
Anyway, if you're near an airport it is probably worth asking about schedul=
es as this might be of some help. Plus you can then express your concerns t=
o a contact who might remember them or at least be in charge of fielding co=
mplaints...
