Re: FRS-1. There are no FRS-1's at all now AFAIK. All were converted to FA.2's. The one in the fleet air museum is a crashed FRS-1's nose grafted onto a GR.3 fuselage, so it looks like an FRS-1. And yes, I was quite tired from the show and long drive home.
Re: F-22 noise. Hmmn. Louder than a Tomcat? Don't know about that, but I certainly felt the F-22 more. Regular Hornets are rather quiet IMHO, as fighters go. Super Hornets are notably louder than normal ones, and certainly "rip" the air much more. No fighter has as much a "ripping" sound as a Super Hornet. F-22 has a distinctive "whoop" sound at low power when it blips the throttle a bit.
I honestly thought the AV-8B was louder than the Sea Harrier, opposite of what I expected.
