Senna collects #27 in Phoenix

On this day in 1991, Ayrton Senna clinched his 27th F1 victory, winning the US Grand Prix in Phoenix. The Brazilian had taken a very late delivery of his McLaren-Honda MP4/6, but the lack of testing was no hindrance for Senna who outraced Ferrari's Alain Prost and Williams boys Nigel Mansell and Riccardo Patrese on the concrete street circuit.

Phillip van Osten

Motor racing was a backdrop from the outset in Phillip van Osten's life. Born in Southern California, Phillip grew up with the sights and sounds of fast cars thanks to his father, Dick van Osten, an editor and writer for Auto Speed and Sport and Motor Trend. Phillip's passion for racing grew even more when his family moved to Europe and he became acquainted with the extraordinary world of Grand Prix racing. He was an early contributor to the monthly French F1i Magazine, often providing a historic or business perspective on Formula 1's affairs. In 2012, he co-authored along with fellow journalist Pierre Van Vliet the English-language adaptation of a limited edition book devoted to the great Belgian driver Jacky Ickx. He also authored "The American Legacy in Formula 1", a book which recounts the trials and tribulations of American drivers in Grand Prix racing. Phillip is also a commentator for Belgian broadcaster Be.TV for the US Indycar series.
