A United Airlines flight was forced to land in Wichita, Kansas, after the evacuation slide accidentally deployed midair.

The slide opened inside the rear of the cabin.

"I heard this pop. I turn around and the slide was open," passenger Michael Schroeder said.

There were no injuries, United spokeswoman Christen David said.

"All passengers were seated at the time the slide deployed. A passenger did not attempt to open the door in flight," David said.

Schroeder said the plane didn't appear to lose cabin pressure and "the crew was pretty calm about it."

"Every landing you walk away from is a good one," he added.
