I went on Sunday. From an observer perspective it was a great time. The weather was absolutely perfect (except some cloud cover at times).
The one thing I thought was a bit off was the announcer / performer timing. Compared to other shows I've been to, the timing between performers and between introduction and actual performer show was crazy awkward.
When the announcer said 120 seconds until the Thunderbirds, everybody stood up to look around as he talked hyping them up and playing the music. 20 minutes later they taxied down to the far side of the runway. 10 minutes after that they took off. The waits wouldn't have been so awkward if the announcers waited until the performers were actually ready ... but oh well.
I thought the Brazilian Air Force Smoke Squadron was pretty cool. I was glad to see they could do the sky writing. I had never seen sky writing before, much less skywriting like they did it. I had in mind the image of the planes looping around drawing out letters. And when they were all in line puffing out lines I thought they were joking around and writing in morse code.
All-in-all, it was a good time.
