Somehow, I had the pleasure of doing our monthly commissary shopping last week. The Air Guard unit in Montgomery AL is transitioning from F-16s to F-35s. One was doing touch and goes at Maxwell AFB. It is the first time I've seen one in flight, nice looking airplane!

Last year we spent a night at NAS Fallon, home of the Naval Aviation Warfighting Development Center (AKA, Top Gun). Yes, lots and lots of noise. Fortunately, they knocked off at about 2230.

That's very cool! I spent about a month and a half at Maxwell for Squadron Officers School (SOS) back in the 80s.
 
I was a little ahead of you Basil, I did SOS in 1978. I did finish my career at Maxwell as the vice commander of CAP-USAF, the active duty component that advises (and monitors) the Civil Air Patrol. The fun part was getting to fly all their varied general aviation aircraft.
 
Sometime in the early '70's I did a TDY to shoot what was then a new "noise suppression" device. ISTR it was at Brooks AFB. Apparently the noise of an F-4 on full AB for final testing after maintenance had become an issue. The "device" was a building that enclosed the entire butt-end of the bird, and as throttle was applied, a HUGE amount of water was sprayed at it. Not certain, but it didn't seem to me it did much to "suppress" the noise... but a monstrous amount of steam/vapor was an impressive result!
 
Costs really spiraled out of control starting in the 60s when they changed from a bid on a contract model to a cost plus one. Then there was no incentive for manufacturers to be efficient. Read once, the first C-5A transport built cost a billion dollars and never flew. It was moved outside for a test flight the next day, caught fire and was destroyed. Some wiring fault was blamed.
