KANSAS CITY, Mo. — UPDATE, Jan. 1 11:30 a.m. | The Kansas Highway Patrol says the preliminary investigation shows the plane took off on Runway 18, headed south. As the aircraft took off, it began to slow, turned over and headed toward the ground.

As the aircraft descended, it struck several trees prior to striking the ground. The impact of the ground caused it to be engulfed in flames. An NTSB investigator is expected to arrive Wednesday afternoon.

As of 11:30 a.m., officials had re-opened the airport.

Tony Molinaro, an FAA public affairs official for the central region, said that a single-engine Mooney M20S crashed "under unknown circumstances" after departing from the Johnson County airport. The aircraft was destroyed in a fire after the crash. Molinaro also said the aircraft was destroyed in a post-crash fire.

The plane was registered out of Shelbeyville, Tennessee.

Video from 41 Action News SKYTRACKER showed a small single-engine plane in a field adjacent to the airport, located on 151st Street between Pflumm Road and Quivira Road.

"We were the first arriving unit here on scene you could see a black column of smoke as you approached the airport," said Captain Mike Hall, of the Olathe Fire Deptartment. "The first unit did get here, and it's a specialized unit. They had some different extinguishing agents on it for an incident like this... used some foam, got it under pretty quick and used some dry chemical powders as well."

A Johnson County, Kansas, Sheriff's spokesperson said the crash happened shortly after take-off.

"When you see the site itself it's very tragic looking more than likely they were thinking recovery at first glance," Hall said.

FAA investigators were en route to the crash site.
