On the ninth of April 1940 around 5:30 a.m. the sound of airplanes flying over awakened me. I lived in Copenhagen close to the airport. I was used to hearing planes coming in from landing all the time. This sounded different. I rushed to the window, gaped at the sky. Hundreds of airplanes like a swarm of giant, gray birds were flying over the roofs on their way to the airport.
