An update on the Asiana Airlines plane that clipped a seawall and crash landed at San Francisco International Airport on Saturday, killing two 16-year-olds and injuring at least 50 others.

American and South Korean investigators today are questioning two of the four pilots of the plane. The other two pilots were questioned yesterday. Investigators want to know why the Boeing 777's speed was too slow to land safely, and why no one realized it in time. And they'll also be talking with air controllers.

Focus now is also turning to the lawsuits that will likely come in the wake of this crash.
