Eighteen riders were left stranded on a Texas roller coaster on Saturday night until firefighters reached them with a ladder truck. The Texas Tornado, an 80-foot steel coaster that opened in 1985, stalled mid-circuit at Wonderland Amusement Park in Amarillo, Texas, during the park’s 75th anniversary season. The double-loop ride tops out at 50 mph and carries 20 people across five cars. Amarillo Fire Department said the ride suffered a “mechanical malfunction.” The Texas Department of Insurance told the station every ride at the park was inspected on June 17.
