In 1895, crowds flooded Coney Island to see America’s first-ever looping coaster: the Flip Flap Railway. But its thrilling flip caused cases of severe whiplash, neck injury and even ejections. Today, coasters can pull off far more exciting tricks and do it safely. Brian D. Avery investigates what rollercoasters are doing to your body and how they’ve managed to get scarier and safer at the same time.
