Whitehall, Pennsylvania - Riders spent more time on Stinger at Dorney Park than they bargained to on Wednesday afternoon. A train full of riders on Dorney Park’s new inverted boomerang sat on its first lift hill for 90 minutes on Wednesday, June 6th. Luckily, the ride was not evacuated from the lift hill, but was able to be restarted with no injuries to guests.

"The ride has a number of safety mechanisms in it and if a safety mechanism detects something it will stop the ride, and when that happens we have to go back and clear it," Jason McClure, Dorney Park’s Vice President, told wfmz.com. It was an alert of this kind that shut the ride down, stopping the train on its tracks.

While maintenance workers attempted to resuscitate the Vekoma-manufactured ride, park operations employees worked to console the trapped guests, according to NBC Philadelphia. They spoke to and delivered water to the unfortunate riders.

According to the Morning Call, a Lehigh Valley newspaper, emergency services were notified after an hour. Before a rescue mission was fully realized, the park’s mechanics were able to bring the train back into the station and return its victims to normality.

"These coasters are machines," Carrie Basta, Dorney Park spokesperson told the Lower Macungie Patch, “and just like your car, an unexpected thing is going to happen once in awhile."

Stinger, and its sister roller coasters have just been unlucky, it would seem. This isn’t the first time the ride has failed to deliver its riders. Before the roller coaster opened at Dorney Park this year, it operated at California’s Great America in Santa Clara, California. During its tenure at Great America, it trapped riders for upwards of three hours on its lift hill.

Another Vekoma inverted boomerang, called Two Face: The Flip Side at Six Flags America in Maryland also trapped its riders for hours on several occasions. Its death sentence, though, involved hydraulic fluid being sprayed onto its participants. It never reopened.

Not all installations of the Vekoma inverted boomerang have been blemished, though. Kings Island, a Cedar Fair park outside Cincinnati, Ohio, has its own, called Invertigo, which has managed to go 13 years without incident.

Despite being transplanted from California, Stinger isn’t the same as it was on the west coast. The ride received an upgraded control system, as well as several of its drives. Despite this, wfmz reports that it has broken down four times since its opening weekend in late April.

The ride remained closed after the incident on Wednesday for an investigation and safety checks, but reopened to Dorney Park’s guests on Saturday, June 9th.
