"It was a really special moment," George says. "I had my whole family there on the grid with me, and I was about to race against so many people who I had looked up to."
With the pre-race ceremony over, there was a job to be done, and a new challenge to adapt to.
"I was enjoying the fact I had achieved a lifelong dream, of course, but there was a realisation that I was now at the back of the grid, not the front."
Consecutive titles in GP3 and Formula 2 may have seemed like distant memories as George lined up P19 for the Grand Prix, but that didn't prevent an important sense of perspective under the visor.
"I knew I could learn at my own pace. I could make mistakes without it being in the spotlight. I could just find the positives from every situation and maximise the year, he adds.
And when the lights did go out, nothing felt new. Something that surprised even him.
"I only realised afterwards, but it felt like any other race. When I was in that car and the helmet was on it felt exactly the same as it did when I was in Go-Karts, F4, F3, or Formula 2. The goal hadn't changed. To drive as fast as possible.
"That was the biggest takeaway for me."
