FORT MORGAN, Colo. (AP) — One person was killed and three were injured when two small planes collided midair as they tried to land at an airport in northeastern Colorado, authorities said.

A Cessna 172 and an Extra Flugzeugbau EA300 collided Sunday morning while trying to land at Fort Morgan Municipal Airport, the Federal Aviation Administration said.

Both planes — each with two people aboard — crashed and caught fire, the Morgan County Sheriff’s Office said.

The two on the Cessna suffered minor injuries, one of the occupants of the other plane was taken to a hospital, and the other was pronounced dead at the scene, the sheriff’s office said.

The National Transportation Safety Board and the FAA are investigating the crash.

Fort Morgan is a city of about 12,000 people about 80 miles (130 kilometers) northeast of Denver.
