[modeleng] Re: scottish inventions

Hello peter and thanks for your comments this is how it goes

Physicist, Sir Robert Watson-Watt, was the mind behind the radar network on 
the coast of England that detected incoming German aircraft in World War II. 
He had worked on the radio detection of thunderstorms (hazardous to 
aviators) during World War I. In 1935 he proposed a method for locating 
aircraft by a radio-pulse technique. The radar system was invaluable to the 
defense of Britain during the Battle of Britain in 1940. It operated day and 
night over a range of 40 miles, giving the Royal Air Force information about 
the height and bearing of German planes.
