John, you're right about the speed of sound. Wasn't thinking straight when I made my original post.
This article has some truly wonderful photos. Caution, you may find yourself laughing out loud: http://www.douglas-self.com/MUSEUM/COMMS/ear/ear.htm
In the UK, the true visionary was Henry Tizard. He was convinced that radar was practicable and formulated the concept of early detection with fighters taking off in time to intercept. His name came into common useage in WW2 due to the "Tizzy Angle", a simple but brilliant idea for vectoring the defending fighters on to the attacking aircraft: http://beyourfinest.com/the-tizzy-angle/
Dowding was the other great figure in this work, who devised what was probably the world's first combined command and control system. This was able to make use of all the info from radar and dispatch our fighters to do their job. The plotting table at the heart of this is a staple for WW2 movies.
The alternative method of defending against enemy aircraft was the old concept of the standing patrol. This would have been hugely expensive in planes, fuel and pilots.
PS: This article suggest a usable range of 5 miles for acoustic locators: https://en.wikipedia.org/wiki/Dowding_system
