Aviation analyst David Soucie on why MH370's still missing
This week a year ago, Malaysia Airlines Flight 370 took off from Kuala Lumpur, with 239 people on board, for what should have been a six-hour flight. It never made it - and it's still missing. There is no confirmation of what happened or where the aircraft resides. Kathryn is joined for analysis by David Soucie, who has thirty years of experience working with the Federal Aviation Administration as an aviation safety inspector and accident investigator. He is the author of the new book, Malaysia Airlines Flight MH370: Why It Disappeared-and Why It's Only a Matter of Time Before This Happens Again.
