Blackburn produced his first machine early in 1910 (see 1911 edition for details). In the latter part of that year he designed the machine which ultimately developed into the _Blackburn_ military. In 1911 other types were produced, all being fitted with the patent Blackburn triple control. School at Filey Hucks has been the principal _Blackburn_ flyer. The type has also been very successfully flown by naval officers. Capacity of works: about 24 a year.
