Just read this on CNN:

"The target air speed for the approach of the flight was 137 knots, and the crew can be heard on the cockpit voice recorder acknowledging the speed, Hersman said.
But the speed was significantly below 137 knots, and "we are not talking about a few knots," she said.
At about four seconds before the plane crash landed, the pilots received an "aural and physical" warning inside the cockpit that the plane was on the verge of an aerodynamic stall, meaning it was about to lose its ability to stay in the air.
The warning -- known as a "stick shaker" -- included a verbal warning the plane that was flying too low and a physical warning when the throttle shook."
