As a very enthusiastic aviator with a lifelong dislike of spectator sports, I think I've found the London Olympics surprising.
Aviation has been a mess. EGTC, where I spend a lot of my time, put in all sorts of restrictions for the huge number of business jets that we never saw - maybe a couple of extra movements per day overall. I personally avoided trying to fly GA in R112 until today - 2 hours of trying to get a flight plan accepted for a short hop out of the zone and I eventually gave up, cancelled my student, and did something else.
But, despite all my prejudices I have really enjoyed watching the games, and have been as bought into the new national obsession as anybody.
