A busy traffic pattern and a controller’s mistaken identity of an aircraft led to the deadly midair collision of a Sabreliner jet and a Cessna 172 near San Diego in 2015, the NTSB found. All four on board the Sabreliner twin-engine aircraft and the solo pilot in a Cessna 172 were killed on Aug. 16 during landing approaches at Brown Field Municipal Airport.
