The following video features real-life audio of a CAP "dogfight" between two F14 Tomcats and two Libyan MiG23's in 1989.(YouTube uploader: TopGunMilitary)
The audio isn't the clearest but between 6.29 and 6.34 during the fight a electronic interference kind of sound can be heard.
I have heard similar noises to this in other videos cockpit videos, what is it? My current suspicion is that it is some kind of "jamming" signal from the F14's as I believe the pilots in the recordings talk about one of the MiG's firing a missile.
Any opinions would be more than welcome
This is another video displaying the same noise at 1.37:(YouTube uploader: BongHitBrian)
