Thom,

Does it happen after a noisy jet flies in? The older jets had what is called a "turbojet" engine, as opposed to a "turbofan" style of engine.

The older jet engines had a core tube where air came in, was compressed, fuel introduced then ignited and the exhaust and thrust came out.

Newer models have a "bypass section" where there is the same core jet section but also a large fan section is added on the front. Depending on the altitude about half of the thrust comes from the large fan but does not go through the "hot section" but around the outside of the engine. This is a lot quiter, uses far less fuel and pollutes a lot less.

Would guess that its one of these that fly over and you are smelling the excess fuel from this.

TurboJet



TurboFan
