Elaine Chao defends FAA amid scrutiny of agency and ties to Boeing

Lawmakers pressed Chao on several aviation safety issues now under a microscope following the twin crashes of Boeing's latest 737 airliner

Chao said the FAA had “no factual basis” to ground the 737 Max until March 13, three days after a Boeing 737 Max crashed in Ethiopia and despite a wave of countries and airlines outside the U.S. that had halted flights in the days before. The tipping point was satellite data and physical evidence recovered from the scene
