Loop-the-Loop

The Loop-the-Loop, was a looping steel roller coaster installed at Olentangy Park in 1908. Designed by inventor Lina Beecher in 1904, up to four riders would ride on a single track down a slope fast enough to do a single inversion (upside-down loop). It was one of the first three operating looping coasters in North America, and its teardrop shape was adapted from a shape pioneered by Edwin Prescott. The shape helped lower the excessive g-forces it put on its riders in comparison to past versions like the Flip Flap Railway. However, the ride still caused many neck injuries, and repeat riders were rare. The ride remained in operation until at least 1914.

The Loop-the-Loop was the only of its kind in the United States in 1913 and 1914.
