1922-1923 The range remained the same, with the addition of a model with a 249cc ohv engine.
1924 The range reduced to the four-strokes that had been constructed in 1922. It was their final year of motorcycle production, and after that the Hawker firm continued with aircraft, right up to the modern-day Harrier.
Harry Hawker, the Australian aviator, was killed while flying at Hendon. Hawker was practising with a Newport machine for Saturday's Aerial Derby. The spectaiors were horrified to see the machine burst into flames at a great height. The blazing plane suddenly took a nose dive, and crashed to earth. Hawker was thrown out as the machine crashed. His legs and arms were broken. The aviator died as a number of persons were running to his assistance.

WII. During the Second World War, the Hawker Siddeley company was one of the United Kingdom's most important aviation concerns, producing numerous designs including the famous Hawker Hurricane fighter plane that, along with the Supermarine Spitfire, was instrumental in winning the Battle of Britain. (During the Battle, Hawker Hurricanes in service outnumbered all other British fighters combined, and were responsible for shooting down 55 percent of all enemy aircraft destroyed).
Almost every Hawker Aircraft design of the Second World War was a success (even if not initially), mainly attributable to the design genius of Sidney Camm.
