The harrowing video aired on a loop around the world -- a passenger airliner gliding down toward the sea near a tourist-filled beach, then tumbling over and over as it struck the water. What happened in Ethiopian Airlines Flight 961 in the hours prior to its crash into the sea near the Comoros Islands required bravery, quick patience, and resourcefulness out of pilot Leul Abate -- and more than a little bit of luck. (My apologies for any audio issues. I had some microphone problems this week.)
