April 11 (UPI) -- Airlines have tested Boeing's fix for its 737 Max jetliners -- after two deadly crashes -- 96 times, company CEO Dennis Muilenburg said Thursday.
Speaking at a leadership forum at the George W. Bush Presidential Center in Dallas, Muilenburg said about two-thirds of the 50 customers with 737 Max aircraft have tested the new software using a flight simulator. The tests amount to about 159 hours of flying time.
