Narrative:
Two CF-100 aircraft operated by 129 Acceptance and Fairy Flight, departed CFS Mountainview, a satellite airfield of CFB Trenton, Ontario, for a delivery flight taking them initially over Lake Ontario. The weather was reported to be very good visibility with high level cirrus cloud. The No. 2 aircraft was approximately two miles in trail of 18469 when it entered the cirrus cloud. Then 18469 disappeared. No Mayday call from the missing aircraft. No trace of wreckage or the two crewmen, F/O L. Tidball and F/O J. Kerr, were never found despite a comprehensive search of Lake Ontario and adjacent land. The crew were presumed killed.

The disappearance of this aircraft has been the subject of an asinine UFO conspiracy theory regarding the fictional "Great Lakes Triangle" proposed by Jay Gourley in a book he wrote on the supposed subject. Such claims are disrespectful to the memory of the crew and to their families and should be disdained and rejected.

The probable cause was hypoxia disabling the crew resulting in a high speed dive into Lake Ontario. Several CF-100 crews suffered a similar fate.
