I filmed several interviews with sir Frank over the years, I could never get used to his daughter Clare calling him Frank rather than Dad. She always had his best interests at heart and would always step in and halt filming if she thought he’d had enough. He was a tough old bird. RIP Frank.
I just watched a clip of Lewis taking two hot laps with Sir Frank as his passenger at Silverstone. Looks to be recent by his age. Must have been the last year of Williams before the sale perhaps. At any rate, he was an amazing person and survived a horrific disability and led from the front in spite of his injury.
