high-tech tethered drone blimp that can carry the radar equipment to watch on a 360 degree level for unidentified aircraft, incoming loaf line cruise missiles. part of the effort to keep especially the washington d.c. capital region areas air defense air safe to keep the air the skies over washington safe. this was undergoing operational testing. here is a really interesting question. norad said no worries, the national capital skies are absolutely safe. they are safe all the time. they have plenty of assets. it s going to, again, perhaps raise questions why are they spending billions on this if already the skies really are safe. good question, indeed. thanks very much for that barbara starr. let s bring in our aviation analyst miles o bryan. potentially they should have shot this blimp down but that would have been a disaster given
