Sir Victor Goddard
Sir Victor Goddard, a British Royal Air Force Officer, was flying a plane over an abandoned airfield at Drem, Edinburgh. During his returning journey over the Drem airfield, he was shocked when he looked down to see the airfield had been completely renovated and was now in use. The mechanics in blue overalls and four yellow planes parked on the runway.
Four years later in 1939, The Royal Airforce began to paint their planes yellow and the mechanics’ uniforms were switched to blue.
