“What harm can a Cessna 172, being trailed by F16’s, do?”
I wonder how many intersections (major transformer farms) of our power grid he flew over while they trailed him. It doesn’t have to be a major city to make a terrorist attack effective. Does NORAD have the grids on its maps?
Maps, shmaps. Do you have any idea what instrumentation is packed into an F-16? It is packed with really fantastic all-weather imaging, GPS mapping, and a huge assortment of things we have not dreamed of.
