New Mexico rescue officials are searching for a Colorado-based plane and its two passengers, who have been missing since Thursday.

The plane was last seen refueling and taking off from Santa Fe Airport at around 5:49 p.m. on Thursday, New Mexico State Police spokesman Dusty Francisco said in an email.

At about 6 p.m., Santa Fe air traffic control lost contact with the plane, a single-engine four-seater registered to American Aircraft Brokers in Englewood.

“The last known location from the airplane’s emergency beacon pinged about a mile south of Tererro, N.M., in the Pecos Wilderness,” Francisco said.

Allen Kenitzer, spokesman for the Federal Aviation Administration, said the plane was reported missing by its owner late Thursday night. An alert notice was issued in response.

“We don’t have any reports of a plane that dropped off radar,” Kenitzer said via email.

A host of New Mexico-based search and rescue teams have been scouring the area of the plane’s last known location since early Friday morning, Francisco said. The National Guard and Civil Air Patrol on Saturday continue to search the Santa Fe National Forest and Pecos Wilderness.
