 Well, you're right, Errol. That's the entire purpose of an investigation is to find out what happened so that we can improve it in the future, keep it from happening in the future. The FAA is indeed investigating this. They will be certainly listening to the air traffic control transmissions to and from the airplanes, but they'll also go back and go and replay the radar data as well. So like you say, they'll conduct the interviews with the controllers and possibly even the pilots as well.
