On Wing Coasters designed by Bolliger & Mabillard (B&M), keyhole elements are common. These elements feature both headchopper and footchopper effects with the train passing through an object only just big enough to accommodate it.
The Keyhole Effect
Wing Coasters are unique in that riders sit in pairs on either side of the track meaning that riders are completely suspended in mid-air with nothing above or below them. The keyhole effect occurs when the roller coaster train passes through the centre of an object, giving the illusion that the train and its passengers have just enough clearance to fit.
The Swarm at Thorpe Park has a perfect example of this as it passes through a large billboard advertising Paradise Airlines and Headeze painkillers (“Don’t lose your head”).

I am passionate about Theme Parks and Attractions. I love riding roller coasters and thrill rides. With two young boys I understand how expensive family days out can be and this was one of the main driving forces behind Attractions Near me. My aim is to help you and your friends enjoy some great days out without costing the earth. Thanks for reading and have a great time - Regards Dan
