The FBI is assisting in a criminal investigation into how Boeing's 737 Max was certified to fly, a U.S. official tells CBS News. Wednesday's development, first reported by the Seattle Times, comes after federal agents told employees at the Federal Aviation Administration's Seattle office to retain documents relating to the approval process for the 737 Max. Boeing's pilot training was under scrutiny Monday as investigators analyzed data from the Ethiopian Airlines 737 Max 8 jet that crashed outside Nairobi, killing 157 people. That information came as officials in Ethiopia said the flight data recorder — one of the doomed Flight 302 jet's black boxes — showed "clear similarities" to the crash of a Lion Air Boeing 737 Max 8 in Indonesia last October. Boeing 737 Max family of planes are shown in a photo provided by the company.
