Alcockcompleted the first nonstop airplane crossing of the Atlantic, on 15 Jun 1919, in a Vickers Vimy, named after a battle in WW I. Brown began his career in engineering before the outbreak of WW I. Like Alcock, Brown also became a prisoner of war, after being shot down over Germany. Once released, Brown continued to develop his aerial navigation skills. While visiting the engineering firm of Vickers he was asked if he would be the navigator for the proposed transatlantic flight. By joining forces with the firm Vickers, Alcock and Brown entered a competition for the first direct transatlantic flight, set up by the Daily Mail newspaper, with a prize of ten thousand pounds. |
