you know, radar only have a certain diameter they can see out ahead of the on going plane. so pilots really refer and reference their onboard radar system to give them that accurate information and it is so accurate that they have a few minutes at least at the very minimum to navigate around big thunderstorm cells like this. when they peak at 50,000 feet in the air, there's no way to get around or even up and over the storms without encountering the worst of the turbulence. >> all right. derrick, thank you for joining us. i want to talk about what the search and rescue teams are facing as they head out. the planes are in the air searching for 8501. we'll take a quick break and continue our breaking news conference this morning of the search for airasia flight 8501. alright, so this tylenol arthritis lasts 8 hours but aleve can last 12 hours. and aleve is proven to work better on pain than tylenol arthritis. so why am i still thinking about this?
