Ferrari has dismissed its head of aerodynamics and wind tunnel John Iley, Italy's La Gazzetta dello Sport reported on Wednesday.Interesting choice of words in the release: a "serious" mistake in the area of the aerodynamics.
John Iley has been working with Ferrari since 2004 and so worked on several championship winning cars, so he's nobody's fool; the fact that he's already being linked to Brawn reinforces that notion.
It sounds to me as if the aero problems on the car this year led to a situation where all involved decided a change would be required. With development set to ramp up on the 2010 car, now is the best time to make that change.
