Two Sioux Falls men had quite a scare Tuesday morning after a flight lesson took a turn for the worse.

A mechanical problem forced the plane to land in a field between Sioux Falls and Renner.

“Luckily, this is one of those stories that has a happy ending,” says Minnehaha County Sheriff Mike Milstead.

It's an ending first responders say they don't see too often… a plane crash where everyone on board walks away uninjured.

"First responders were here within minutes, they were able to locate the aircraft, pilot and other passenger right away,” Milstead says.

The certified flight instructor and a student were practicing approaches when the plane had an engine failure. They landed in this corn field just north of the Sioux Falls airport.

When authorities arrived at the scene, they say the men were calm, and happy to be alive.

The plane landed in the field north of interstate 90, by Catfish Bay, making it hard to see for the responders. They used a nearby farmer's four-wheeler to beat down a path, and locate the two men.

Milstead credits the flight experience of the pilot and passenger for the good outcome.

"This took some skill to be able to bring it down. It took some thinking because they were in areas very close to populated areas and they were able to set it down in a corn field,” Milstead says.

A landing and an ending with a sigh of relief for everyone.
