The '''BAT F.K.28 Crow''' was a British single-seat ultralight aircraft produced by [British Aerial Transport Company Limited](/source/British_Aerial_Transport) of [London](/source/London). It was intended to be the "aerial equivalent of the motor cycle".<ref name=Flight010120p18>{{cite magazine|title=Some "BAT" Aeroplanes|magazine=Flight : The Aircraft Engineer and Airships |issue=575 |volume= XII No.1 |date=1 January 1920 |pages=18–19}}</ref>

==Design and development==
The smallest of designs from [Frederick Koolhoven](/source/Frederick_Koolhoven) when he worked for the British Aerial Transport Company was the '''F.K.28 Crow'''.  It was very small and light high-wing monoplane, with a conventional tractor configuration.  The monoplane's [tail surfaces](/source/Empennage) were carried by [two slim booms](/source/Twin_boom).  An [ABC Gnat](/source/ABC_Gnat) 2-cylinder [horizontally-opposed engine](/source/horizontally-opposed_engine) - together with fuel and oil tanks - was mounted on the wing centre section. The pilot's seat was set between the landing gear suspended below the wing. It was designed to be dismantled for road-transport with the removal of twelve bolts. It was displayed at the First Air Traffic Exhibition in [Amsterdam](/source/Amsterdam), but it did not fly until some time later. It only flew once and proved to be underpowered.  It was scrapped in 1920.
