When Fernando Alonso guided the new McLaren-Honda out of the garage shortly after the track opened at Jerez on Tuesday morning, it was not just the excited Spanish fans who were delighted that their man was in action.
The relief on the faces of everyone inside the McLaren garage was clear to see. After two days of deep frustrations, as engineers from the team and engine partner Honda chased glitch after glitch on the new turbo engine, finally its testing programme could start properly.
As Alonso returned to the garage after the installation lap and reported zero problems with car and engine, the confidence grew. Longer and longer runs followed, lifting spirits further.
