Green engines powered many pioneering British aircraft, including those of A. V. Roe, Samuel Cody, and Short Brothers.
The best known case is John Moore-Brabazon's winning the £1,000 Daily Mail prize for a circular 1 mi (0.87 nmi; 1.6 km) flight by a British pilot in an all-British aeroplane in his D.4-powered Short Biplane No.

One interesting detail seen on many modern motorcycles was 'the fitting of a glass window in the crank case to show the level of the oil'.
