Oh dear... the force on a clutch acts parallel to the shaft - obviously.

| Which part of the Concord did HE design?
|

He designed a go/nogo DTL autotest of four analogue computers.
A dummy step voltage is integrated by the computer and a ramp starts.
A predefined output voltage is timed and a time window is opened and
then closed.
If the output voltage doesn't trigger a threshold detector within the
window, the computer fails and the plane doesn't take off, it failed
a pre-flight check.
The computer is pulled, another installed and life continues, the faulty
computer is returned for repair.
Nothing to do with frogs leaving shrapnel on a runway.
Nothing a mere physicist would understand.
