Both planes were getting ready to land at a small regional airport in a Denver suburb on Wednesday when they collided mid-morning, according to the National Transportation Safety Board and South Metro Fire Rescue.

“Every one of these pilots needs to go buy a lottery ticket right now,” Arapahoe County Sheriff''s Deputy John Bartmann said. “I don''t remember anything like this — especially everybody walking away. I mean that''s the amazing part of this.”The pilot was the only person aboard a twin-engine Fairchild Metroliner that landed at Centennial Airport despite suffering major damage to its tail section. The plane is owned by a Colorado-based company called Key Lime Air that operates cargo aircraft.

A pilot and one passenger were on the other plane, a Cirrus SR22 single-engine plane that unleashed a red and white parachute to float to a safe landing in a field near homes in Cherry Creek State Park, Bartmann said.

It was not immediately known who owned the Cirrus plane, he said.

The National Transportation Safety Board said in a tweet it was sending staff to investigate the incident. Key Lime Air will cooperate with the investigation, the company said in a statement.
