Canadian officials are taking over the investigation into a deadly Memorial Day mid-air collision because the planes involved were owned by federal aviation and transportation officials.

The National Transportation Safety Board said Tuesday that one of its employees owned the six-seat Beechcraft BE-25 in which two people were killed in the collision in Fauquier County. The medical examiner's office has yet to identify the two victims.

The pilot of the other plane -- a Piper PA-28 -- is an employee of the Federal Aviation Administration. Seventy-year-old Thomas Proven was listed in good condition at a local hospital Tuesday. He declined interview requests.

NTSB Chairman Deborah Hersman and FAA Acting Administrator Michael Huerta requested that the Transportation Safety Board of Canada conduct this investigation
