SheiKra is a Bolliger & Mabillard dive coaster at Busch Gardens Tampa Bay, open since 2005. It holds you over a 90-degree drop for about four seconds, then lets go. Then there’s a second vertical drop, an Immelmann loop and a splashdown that throws two huge sheets of water into the air. It was the first dive coaster to have one.
It’s named after the shikra, a hawk that dives on its prey. The trains have been floorless since 2007, so there’s nothing under your feet while you hang there.
