WARRENTON, Va. (AP) - Canadian officials are continuing the investigation into what led two small, private planes to collide in mid-air on Memorial Day in Fauquier County.
Two people were killed and another injured in the May 28 crash near Warrenton-Fauquier Airport.
The crash is being investigated by the Transportation Safety Board of Canada because the pilot of one of the planes was a National Transportation Safety Board employee and the other plane is owned by an employee of the Federal Aviation Administration.
Officials Wednesday said the investigation team is working to determine what caused the crash and how to stop it from happening again. Investigator Jon Lee says they're focusing on whether the aircraft were visible to each other before the collision and what role traffic control may have played.
