From the Wikipedia article

The Convent Crash, also known as the Orléans air disaster and Villa St. Louis disaster, occurred on May 15, 1956, after a CF-100 fighter jet crashed into Villa St. Louis, a convent in the community of Orleans, Ontario, Canada, a suburb of Ottawa. The two pilots were killed in the crash, along with 13 people in the building: 11 members of the Grey Nuns, a civilian servant, and the chaplain, a retired naval padre.

Events

At 10:37 p.m. May 15, 1956, two CF-100s took off from their base at RCAF Station Uplands (located south of Ottawa) on an exercise to practice interception techniques in identifying an unknown aircraft heading towards Montreal. The plane was identified as a RCAF North Star flying from Resolute Bay to Dorval Airport. The two planes climbed to 33000 ft and burn off excess fuel before returning to base.

One of the aircraft returned to base, but the other remained airborne longer to burn off more excess fuel. The plane descended at a speed of nearly 680 mph and crashed into the Villa St. Louis. The cause has never been officially determined, but it is thought that an oxygen failure caused the crew to pass out.
