some personal notes: as historical researcher about air war over my town, is a sad thing that reasearching over british planes is more difficult than researching about American planes. Yankees have a lot of online associations, veteran forums, missions summary and a lot of other interesting stuffs. The British side of the matter has ever been more and more difficult, a warm thank to the 12O'clock High forum members to their patience and thier gently
