Většinou si černé kroniky všímají jiní, tak dneska zkusím:
[ Link ] Dan Gurney je (mimo viz výše) známý též "odtrhovou hranou, tzv. Gurney flap"
[ Link ] která v kostce zvyšuje přítlak bez extra navýšení odporu
Něco málo z doby vzniku/objevu: "Unser realized the value of this breakthrough immediately and wanted to conceal it from the competition. Not wanting to call attention to the devices, Gurney left them out in the open. To conceal his true intent, Gurney deceived inquisitive competitors by telling them the blunted trailing edge was intended to prevent injury and damage when pushing the car by hand. Some copied the design, and some of them even attempted to improve upon it by pointing the flap downwards, which actually hurt performance."
