I attended a sporting event where they did a “very low” flyover, and it was awesome! I remember it clearly because I looked at my brother who was with me right after the flyby and stated with shock how low they were. This was in St. Louis and Busch Stadium for a Cardinals playoff game years ago. Don`t recall anything being said about it in the media afterwords though.
Watched the YouTube video...that’s about the altitude of the flyovers at the old Sears Point Raceway (I refuse to call it “Infineon”).
For many years, my son and I watched the Blue Angels perform at the San Francisco Fleet Week show on the Marina Green. That seemed to be the altitude that they flew over the crowds. Now that was really magnificent — no trainers there.
