They said the ride purposely stopped as a safety precaution. Can someone please tell me how a gravity powered coaster can purposely stop?

[Edwardo]

Since the live feed is gone, I can't see where the ride stopped. If it stopped on the midcourse then that's how it's designed. If it stopped in the cobra roll then that's also a design feature when there wasn't enough launch speed.

[Chris]

It was the cobra roll.

[Jay]

It actually wasn't the cobra roll, but just after.

[Chris]

Oh, you're right. My fault.

The News lady on WXII 12 just said that the incident occurred at Six Flags Great America

Two questions:
Looks like the valley is jist after the highest point?
Why would the ride purposely designed to stop in cobra roll and how?

[Jarsh]

It isn't designed to stop there. It stalled/valleyed there on accident. I'm guessing something happened to the wheels for it to stop there. If the launch had misfired it wouldn't have made it through the cobra roll or immelmann I would think.

[Chris]

Six Flags is making it sound like the ride immediately stopped when it detected a problem. Since I know how gravity works, I realize they are full of it but it's interesting to hear them spew this BS nonetheless.

Yeah seeing where it stopped it seems like an issue with the wheels or something.

As for designing to stop in a cobra roll, notice that on Cobras roll there is a catwalk. On sit down boomerangs as well as the spaghetti bowl launchers, that is an "expected" for lack of a better term, valley point.
