'Technical difficulties' ground Stunt Pilot

It's been an up-and-down year for rollercoasters at Silverwood Theme Park.

Its newest rollercoaster has been closed due to "technical difficulties."

"Stunt Pilot will be temporarily closed as the manufacturer, Rocky Mountain Construction, works on fixing the coaster," says a notice on Silverwood's Facebook page. "They are working around the clock to get it back and running as soon as possible."

Stunt Pilot has been closed since Wednesday. It opened this year and has been popular, with long lines. The single-rail coaster climbs over 105 feet, includes hairpin turns and three inversions "as the coaster speeds through heart-stopping obstacles before returning back to the hanger."

"Stunt Pilot has been extremely popular and has brought new thrills to visitors from all over the country," wrote Jordan Carter, Silverwood spokesman. "Rocky Mountain Construction has a reputation for creating some of the best coasters in the world, and Stunt Pilot is no different. Adding this fifth coaster fits perfectly within our coaster lineup and we are excited for more people to be able to earn their wings before the season is over."

Silverwood management said as soon as Stunt Pilot reopens, it will alert customers.

In late June, riders on "Aftershock" were stuck for about 20 minutes before being evacuated. The ride was soon reopened.

"Aftershock was stuck earlier this season, but when it does that, it means it is actually functioning properly," Carter wrote. "This is because if a sensor has a miscommunication, the ride will stop because it isn’t getting a communication from a certain part of the track. It is a safety feature for it to stop like that."

In early June, someone cut through Silverwood's fence off Brunner Road at about 1:30 a.m. and ran a line of gasoline to Timber Terror, one of the park's two wooden coasters, set it on fire and fled.

Night security personnel saw the glow, ran over and doused the flames with a fire extinguisher. Crews replaced some damaged boards and Timber Terror was open the next day.
