RIP to all on board. I too fly a lot for work; i.e. have flow twice around the world in the last four months. In March one of my flight segments was Hong Kong to Paris on Air France, which brings this whole tragedy a bit close to home.
While flying over China we hit major turbulence and for the first time in a long time I began to get a bit nervous. The Captain finally announced that he had requested a change in course, but the roller-coaster ride continued for 30-45 minutes; a couple of the overhead bins popped open.
The plane was going sideways, up and down and the yaw... I just looked out the window and gathered the Mormons, who were going on mission, to pray. I never prayed that hard.
