On this week’s episode of AvTalk, Boeing CEO Dave Calhoun is back in front of Congress. A trio of stories involving Southwest Airlines, including an apparent incidence of Dutch roll, a roller coast ride off the coast of Hawaii, and a system on the CFM LEAP engines that pilots apparently didn’t know about. And investigators are trying to understand how counterfeit titanium made it into Airbus and Boeing aircraft. Thank you for listening! Thank you so much for listening to AvTalk! Like the podcast?
