Jerry,
The sound of all those Merlin engines at close call is still rattling around in my head

I once flew on a scheduled DC3 flight in the backwaters of Mexico in about 1985 - quite an experience climbing over the Sierra Madre.
Regarding Parry Thomas's Babs, she lives part time in the Brooklands Museum and part time at Pendine in Wales - and of course, sometimes runs at events such as Goodwood.
She's looks to be quite a struggle around the corners, with the torque of the low revving 27 litre Liberty engine.
