Canadian aviation officials will take over the investigation of a collision between two small planes that killed two people Sunday. The planes involved in the midair crash over Fauquier County, Va. were owned by employees of the Federal Aviation Administration and National Transportation Safety Board.

So, because each aircraft was owned by a U.S. transportation official, the investigation is being turned over to the NTSB’s northern counterpart, the Transportation Safety Board of Canada, WTOP reports.

Authorities have not identified the two victims in the crash, who were on board a six-seat Beechcraft BE-25 owned by an NTSB employee. The pilot of the second plane, a Piper PA-28, was Thomas Proven, a 70-year-old FAA staffer who survived the collision and is listed in good condition at a local hospital.

“This accident hits especially close to home, with the involvement of an NTSB employee,” NTSB Chairman Deborah A. P. Hersman said in a press release. “I’m grateful to TSB-Canada Chair Wendy Tadros for agreeing to conduct the investigation and the NTSB stands ready to support and assist them in any way we can.”
