Before air shows were regulated almost out of existence, I was at a air show mid 80's.
The announcer said the P-51 was 20 miles away and what seemed like a only few minutes he flew overhead maybe 40 feet off the runway and overtop the crowd at approx 400-450 mph. Do that today and your pilots license would be pulled.
The vibration was so strong your feet was bouncing on the ground or at least it felt like it.
Late in the day my brother and I and two friend were offered a ride in a B-25 for $50 each but we had no money right out of college - I was a $200 week millionaire and he was just married .
They guy came back and said $40.00 each. he only had a few people and wanted more heads to make it worthwhile to take the plane up.
MY brother and I still kick ourselves to this day
