I think the Porche was probably the fastest. Can't see the speedo in the onboard video but looking at the rev counter wazzing around the dial, I reckon he must have been close to 140ish. The single seaters are capable of 140 and he was maxing his in top.
The Lambo was probably the slowest cos his instructor kept telling him to change up all the time whenever the revs started to climb a bit too much !. Actually, a Lambo is more of fast road car, somewhere where you can let her really get the motor spinning
And thats some interesting reading ref Thruxton during the last big one, thanks for posting that. Within a ten mile radius of my house there are 9, yes nine ! WW2 airfields. Some are now all agricultural, but some of the buildings still survive....I tell you, navigation must have a been a real peach with all these landing sites dotted around the countryside.
