Three people were killed when two small planes collided in midair near McKinney in Collin County on Saturday.

The aircrafts flew into each other around 5:30 p.m. near Aero Country Airport, a private facility located roughly 35 miles north of downtown Dallas.

Fire officials said one of the planes ended up on a nearby road, while the other flew into a storage business.

According to the Federal Aviation Administration, both planes were flying under visual flight rules, and they were not in touch with any air traffic controllers when they collided. Investigators said the Aero Country airport does not have an air traffic control tower, so pilots use radio frequencies to announce their takeoffs and landings to other aircrafts.

Specifics about the cause of the crash were not immediately available. But, the FAA and the National Transportation Safety Board are both investigating.

NBC News has identified two of the victims as Tim Barber and Gregory Barber. The third victim had not been identified, as of Sunday night.
