A roller coaster malfunction turned a school field trip into an hours-long rescue operation on May 28, after eight students were left stuck nearly 100 feet in the air at Galveston Island Historic Pleasure Pier in Texas.

The students were riding Iron Shark, the park’s tallest coaster, when the ride stopped while climbing the track. Instead of getting the promised Gulf Coast drop, they got the less marketable version: waiting high above the pier while firefighters figured out how to bring everyone down safely.
