concern to us. >> all right. thanks so much for joining us. those are just two of the affected airports. there are 147 others throughout the country that also have to power down. starting ape 7. tom foreman is standing by to explain the impact it might have on you. >> you know, jake, they are absolutely right when they say it is a safety matter. there are really communities all over this country that have small airports like that and all day long they handle thousands of planes that come in and out. they track their movements as they come in. they keep tra of what is going on on the runway. there are vehicles on the runway, other planes cleared. all sorts of things going on here. if you take the air towers away, if the airport is still there, is this plane flying blind? no. it is not. because exactly what the mayor was alluding to. othe airports will then be in charge of tracking or communicating with this plane in most cases.
