Boeing (BA - Get Report) stock fell 2% Wednesday after a New York Times report said a senior engineer at the Chicago aerospace major this year filed an internal ethics complaint during the development of the 737 MAX jet.
The Times report says the company "had rejected a safety system to minimize costs, equipment that he felt could have reduced risks that contributed to two fatal crashes."

Boeing shares at last check were down 2.3% to $366.37.
