The Hornet Flight - Follett

Another good book from Ken Follett. A twisted story set in East Anglia and the Danish island of Sande where a crude but effective RADAR station is directing German interceptors to shoot down incoming British Bombers. The site is discovered by a young hero type who together with a young pretty girl type manage to survey the site, determine how it works, then barely evading capture - fly an antique bi-wing, fabric covered wood plane found in an otherwise empty barn to England with map locations and information about the German RADAR that helps the air ministry direct planes avoiding detection, etc. It's a good story well written.
