Quite interesting reads!
The oil breather issues were really front and center for these guys.
Thanks for posting!

Can you imagine kneeling in the passenger seat facing backwards, watching the valve cover breathers while David Hobbs hurtles the car around Sebring?

Working on the design of an early Lotus race car, Frank Costin has that topped.
Cutaways behind the front arches, to improve brake cooling, were the result of aerodynamic tests on the Mark VIII during which Frank Costin was strapped to the bonnet and driven up and down a Cheshire airfield. “Colin and I did the driving and Frank did the laying on the bonnet! He couldn’t have done that with the Mark IX works cars, neither of the bodies would have stood him. The wool tufts he was watching were all underneath the wheel arch — he wanted to see which way the wind was blowing behind and inside the wheel. We were getting up to 100mph or so.”

The narrator of that story is his brother Mike Costin, the "Cos" of Cosworth.

I might imagine Frank Costin doing that...but NOT me!
