Formula 1 Team Principals have a lot to do. They have to manage the drivers, engineers, mechanics, designers and hundreds of other employees at the racetrack and in the factory. Team Principals lead them all through wins, podiums and retirements. If things don't go well, they sometimes pay with their jobs.

Aston Martin's Team Principal Mike Krack tells Katie and Christian about his job and how it differs from his fellow bosses. Plus, how he manages drivers, keeps on top of the rulebook and why he chooses to watch races from the pit wall, not the garage.
