It might be worth noting that early '917s', other than the 907s steelframe, were flimsy aluminium (or magnesium) tubes with negligible downforce. Meaning a highly flammable Gfk covered leaf in high gusts. Just look at the Woolfe Racing wreck. Siffert, Elford, Stommelen and the german works drivers had to be fearless absolute magicians to race them things. Apart from that I think Mario Andretti looks every inch the epitome of a racedriver. Thanks for the great document.
Ive made a similar comment on another video of the 917 being not as robust as the 512 Ferraris in the 1970 season and that upset many a Porsche keyboard warrior. Even the Aluminum tubed 917s were not meant to last more than 1 or 2 long races. No hate on the 917s they were incredible cars at the cost of strength.
@@simeonorive145 I can't remember if it was Elford or Redman or someone else, but the early 917s had a pressure gauge on the chassis, it was filled with some inert gas to confirm no cracks. When the pressure went to zero, park it, because the frame's tubing had cracked.
In one 70s NASCAR cheating episode. The car body was etched with acid making it paper thin. An inspector put his clipboard on the roof & noticed it sank into the roof.
That red Alfa Romeo at 2:32 looks great.
Fantastic coverage for the time !
My Boy Scout troop worked as runners in the press box. Fond memories.

these „early 917s“ are actually 907s.
@@peterkissinger9696 Thank you, I will change my comment accordingly.
