The Cavity Magnetron was invented by A W Hull and General Electric in 1921. A number of
others, including Germans, contributed enhancements over the years. The British version
had greatly increased power and was the first practical for use in airplanes. It was
certainly a major step forward, but not the "invention of radar" as many would have it.

The discovery of penicillin was probably a more unique discovery.

That's funny I though thge cavity magentron was invented by the British
and smuggled to the US in a sock. Come to think of it, the British
seemed to like that ploy as they also used it to smuggle penicillin to
the US as well!

Why do you assume that radar would not have existed without the Brits help? Its true
that
significant improvements where made in England, especially to the cavity magnetron
(itself
an American invention), but this was a technology rapidly advancing in a number of
sites.
In the US, the Radiation Laboratory (or RadLab) at MIT was funded at the same level as
the
Manhattan Project, and surely would have duplicated most of the British work in a
matter
of months. Given the significance of the work, of course, that several months was
rather
important.

What would the US have built without being given the design of the
supercharged merlin engine? What about radar? Makes one wonder...

Sure Donal,

Peace in our time was said just after Adofl went into Austria and before
England went to War.

U.S. went to war 12/7/41

Now,Donal, Maybe you would like to give the group a list of the Battles
that the Brits won in that time?


The Battle of Britian comes to mind. If the British had lost, then the
outcome of the American war with Japan could have turned out very
differently.





Your refernce was a Joke? At whose expense?


The Californian electorate.
