The Super Bowl fly over was kind of random. My son said it was f18s, f35s, and f15s. I was able to make out the two b1bs. It was like the air force forgot about the flyover and just scrambled whatever was on the closest tarmac.

Caveat: A non-trivial number of air assets are currently stationed or assigned on the other side of the world right now.
Citation: I used to be involved with flyovers.
Using a few planes for a fly-by, particularly of anything other than B2, wouldn’t possibly “give away” any info.
