EAST HAVEN, Conn. (AP) — Workers have torn down the Connecticut home of two children who were killed when a plane carrying a former Microsoft executive and his teenage son crashed into the residence.

The East Haven home was demolished Wednesday morning. A neighboring house also struck by the plane was knocked down last week.

A 10-seat plane approaching Tweed New Haven Airport crashed into the houses Aug. 9. Thirteen-year-old Sade Brantley and her 1-year-old sister, Madisyn Mitchell, died in their home. Their mother survived.

The crash also killed the plane's pilot, Bill Henningsgaard, and his 17-year-old son, Maxwell, of Medina, Wash.

The cause of the accident remains under investigation. The National Transportation Safety Board has issued a preliminary report saying a witness saw the aircraft traveling upside-down as it sped nose-first toward the ground.
