Girl plummets to the ground from Six Flags gondola ride—with only a crowd below to catch her.

With summer officially in swing, kids are headed to theme parks across the country. But as we recently saw with a brand-new California water slide that sent a boy flying out of it, some of these thrill rides aren't as safe as you'd hope.

The latest heart-stopping incident, described by witnesses as "horrifying," occurred at Six Flags Great Escape, in Queensbury, New York. In the video below, you'll see a 14-year-old girl who screams as she dangles from a stopped gondola ride she'd been in with a younger relative. With seemingly no other way of getting girl to safety, a crowd gathered to catch her when she finally fell—and she hit a tree branch on her way to the ground.
