A fantastic movie. If you haven't seen it you should. The motorcycle Scene with Steve McQueen is a classic.
1927 BARC Whitsun Monday Meeting. Brooklands, Great Britain. 6th June 1927. Henry Segrave demonstrated the 1000hp Sunbeam in pouring rain at this event, but the track was "too wet to allow its real acceleration to be shown". World Copyright: LAT Photographic.
