On a web-site dealing with film sound cliches, there's the following example: “An approaching airplane or helicopter will make no noise until it is directly over the characters, at which point it will suddenly become thunderingly loud.” Here's a recording of an F 15E Strike Eagle doing a fast pass at Duxford Airshow. Judge for yourselves how much of cliché this is and bear in mind that the plane is traveling at around 300 mph - about a fifth of the speed of which it is capable. There's no fade in before the plane arrives and this is the only recording that's usable from the batch that I made, as in almost every other pass, all the car alarms in the car park went off as the shock wave hit. You really don't hear these planes coming, but you sure know when they've passed.
