Sir Frank Williams graduated to Formula 1 in 1969, and he did it with an immaculately-prepared dark-blue Brabham BT26 and the talented Piers Courage.
One year later, Williams switched to a De Tomaso chassis built around the readily available Cosworth DFV. Often outpaced by the bulk of the field, it was a slow start for both car and driver in 1970.
Courage did his best however to grab the uncompetitive machine by the scruff of the neck. The Brit qualified well at Spa but was sidelined early on by reliability issues.
Alas, tragedy struck at the following race, the Dutch Grand Prix at Zandvoort, where Courage slid wide after a suspected tyre failure, ran up a banking and crashed, perishing in the flames fueled by the car's magnesium tub.
It was a huge blow to Williams and to British motorsport. Piers Courage was just 28.
