That documentary, “One” was great about early F1.
The only horrible thing was the annual carnage where so many great drivers lost their lives.
I also recommend “Gull Wing at Twilight” that is usually shown on some PBS stations from time to time which features the life of driver John Fitch as he prepared to run a modified MB Gull-Wing at the salt flats at 84 years old.
