Al Pease's Eagle Climax in the 1969 Canadian Grand Prix - shortly before he became the only driver ever to be black flagged from a Championship GP for driving too slowly.
This is what I posted a year ago on the passing of Al Pease:
"As for his unfortunate footnote in F1 history, if should be noted that he qualified the same Eagle-Climax 4 in mid field for the 1967 Canadian GP. He qualified but dns the 68 race due to engine problems, so by 1969 the old Eagle was surely tired and out classed"
Pease's actual qualifying time was faster than Lovely, Moser and Cordts and was within the 90% guideline of Ickx's pole. So it was in the race that he lacked pace. I know this is often quoted but have trouble believing it never happened anywhere else over 64 years. A sad note to have brought up in one's obit.
