sentences:  Watson's new aeroplane was powered by a 1910 three cylinder 30 hp Humber engine.A number of accounts state that Preston, his younger brother James and Archie Dickie, who had allegedly gone to Paris to secure a Dutheil Chalmers engine from Alberto Santos-Dumont for Watson's previous aeroplane, all flew the machine at Errol at this time.The pictures published in the 15 May 1914 issue of "Flight" magazine, which captions the images as having been taken in 1912 have been mis-quoted by James as having been taken in 1908, but the No.2 was built in 1910 and its 30 hp Humber engine was not produced until that year.
