BLACK MARIA

The all-Canadian B Flight of No. 10 (Naval) Squadron, equipped with Triplanes, downed 87 enemy aircraft between May and July 1917. Called the Black Flight because of the black markings of their airplanes, their aircraft were named: Black Maria, Black Sheep, Black Prince, Black Roger, and Black Death.
"Black Maria" no N5492 was the highest-scoring triplane of all of them credited with no fewer than 23 kills. 18 of these were scored by Raymond Collishaw. Later for short time Callishaw was also using second "Black Maria" no N533 which was armed with two vickers.
