Following up on his 1926 patent, former British aviator John Norman Bartlett worked with John A. Miler to design and build Flying Turns, a Bobsled Coaster where the train free wheels through a trough (a.k.a chute), at Lakeside Park in Ohio, USA. Instead of sitting side-by-side, riders sit in a single row behind one other, similar to athletes in a bobsleigh.
Flying Turns at Knoebels Amusement Resort in Pennsylvania, USA opened in 2013, some 40 years after the last Bartlett model was destroyed.
