(KPLR) - For the second day in a row passengers are escorted from a ride at Six Flags in Eureka.
This time it was the Screaming Eagle.
A Six Flags spokesperson says the ride is designed to shut-down during the "uplift" if the ride's very sensitive computers detect anything unusual.
Passengers were escorted down a walkway alongside the track, and the ride ran empty for a few cycles before it was cleared for passengers again.
Friday 4 students were sent to the hospital, when the boomerang ride came to a halt.
Emergency crews were called to the park around 11:30 am after one of the cars derailed.
The park was open for a group of high school students on a special field trip.
That ride will be closed for a thorough inspection before reopening.
