I was surprised to find out the amount of aircraft produced at Ringway before, during and after WW2 - in total some 4,428 from Fairey's and 109 by Avro. Started with the Battle in 1937 and ending with the Gannet in 1958..
I've never heard of Empire Day before. Apparently it was celebrated on the 24th May starting in 1902. Empire Day remained a part of the calendar for more than 50 years,. By the 1950s however, the Empire had started to decline,and in 1958 Empire Day was renamed as British Commonwealth Day, and in 1966 it became Commonwealth Day. The date of Commonwealth Day was changed to 10th June, the official birthday of the present Queen. The date was again changed in 1977 to the second Monday in March,
