True. Where I wrote "never saw fruition" I should have written "was
sidelined". Instead, he designed the spherical bomb and refined that
into the cylindrical bomb used to breach the dams.

Apparently the diameter of the spherical bomb with the right amount of
RDX would have been too large to fit under a Lanc. It was changed to a
cylinder to reduce the diameter and the spinning used to give it
gyroscopic precision so it hit the water horizontal each time.

Phew John. I opened a can of worms here by mentioning the program I saw.
It said the bomb was designed to hit the dam wall, bounce away, and then
the gyroscopic motion would claw the bomb back to and down against the
wall to detonate at predetermined depth.

The spin was primarily designed to work the same as spin put on a golf
ball to keep the bomb against the wall, and not as a trajectory aid.
No?
