Red Bull‘s termination of Christian Horner has sent shockwaves throughout the world of Formula One. A formidable presence in the sport, Horner had helmed Red Bull Racing throughout its rise and dominance.

Red Bull has lost several key figures across the past 18 months, most notably design legend Adrian Newey, Sporting Director Jonathan Wheatley, and Chief Designer Rob Marshall. The sacking of Horner means that a fourth pillar of long-term success is gone.
