And, just in case it's not obvious to everyone, that's certainly a DH.88 Comet and presumably G-ACSS behind them as I guess the race was about to start.
The aircraft is airworthy at Old Warden, although with some substantial replacement components during the restoration some years ago. As it's now 84 years old that sounds pretty reasonable.
I've got a copy of "Scott's Book" around somewhere, written just after the race. An author he wasn't...
