Old email I recd from a retired Nam pilot friend.
Over the years we’ve all rec’d assorted videos of planes flying; one the best - go full screen....
This footage is of the "slot man" in the Diamond formation...toughest flying due to wingtip vortices, etc...when he "smiles", he is pulling some serious positive/negative "g" forces. Very cool.
What a ride! Notice the rest of the formation in the Pilot's reflective goggles!
