Airshows used to be many in Calif, no more. Back when they were popular, and many, I was fortunate enough to live under the flight path for many WWII planes flying to and from the airshows. My son and I once counted around 50 planes flying overhead all visible at the same time.... of course not ALL of those were WWII planes but many were.
They would fly in small formations... maybe 5 or 6 in each formation. Anyway... your video reminded of that. - JamesJM
