Don't you love people who first buy a house near an airport and then... complain about the airplane noise!
I could understand in the case of a new airport or perhaps a new runway (although freighters at FRA use the old 07/25/18 runways, not the new 07L/25R). Often the very same people complaining got the house at a cheaper precisely because it was near... an airport.
I would put people like that on a general no-fly list, next holiday they can walk to their destinations...
