Handley Page Hampden

The Handley Page HP.52 Hampden was a British twin-engine medium bomber, serving the Royal Air Force at the outbreak of the Second World War. The Hampden, known as the "Flying Suitcase" because of its cramped crew conditions, was still unsuited to the modern air war and, after operating mainly at night, it was retired from Bomber Command service in late 1942.
