Late 70's Red Arrows at Brands Hatch for the Grand Prix flying their V formation high above.
As everyone's watching them high up going to the left over Paddoch Hill bend, when enter right coming up BELOW the stand at full throttle came a single Red Arrow, dropping down below the height of the tower at the back of the pits & out the other side.
Not allowed to do that anymore... but Frak me, was awesome & those people in the Paddock Hill bend stand went everywhere ...
