When the Braves have some important game (not this year beyond OD and the All Star Game), the jets prep by flying circles near us, we can really hear their engines. The ASG features two F22s and a C130, the latter being a bit odd, but they are built up near the stadium. It's kinda fun watching them a bit, and I wonder how much they interfere with operations down at the airport about 10 miles south of me, but I think they don't.
The ATL runways are all E-W and we're to the north so we don't generally hear passenger jets.
The flyovers are for recruiting, imagery, and to give flight time to pilots, who have to fly for that one way or the other. One reason I stopped flying is the requirement to have 3 landings every 90 days, not an unreasonable requirement. But you end up spending maybe $80, probably more now, going to the airport, preflighting, firing it up, taxiing out, running it up, taking off, circling back for three touch and goes, and then shutting down, driving home. This is why pilots will have $100 hamburgers at times.
