The shaking so violent, some passengers afraid they weren't going to make it. A crew member even breaking his leg. Here's Zachary kiesch.

Then seeing blood all over. Reporter: A bloody handprint, visible, as passengers tried to steady themselves. Some were slashed on the head and back. One flight attendant broke her leg. The severity clear in this exchange with the tower. Do you have a doctor onboard? We do. He's helping her right now. But we're going to need assistance after the landing. Reporter: A passenger told us, although the seat belt light was on, many were standing to stretch after a long flight. A lot of people jerked up, some people hit the ceiling. Some people hit the sides of the it really just came out of nowhere. It was pretty dramatic, and you could definitely feel the zero gravity sense of dropping.
