Watching the clip, it seems that they're being ultra-cautious since you can't see the tail number, so they waited until getting verification from multiple sources before running it. That part of it is a welcome change from their terrible coverage of the Boston Marathon bombings, with many false stories and "a lot of cars are going by, Wolf! Something is happening, we just don't know what" breaking news updates. Now the pendulum has swung too far in the other direction. Awful to see what CNN has become.
