Can this be considered a terrorist threat?

Any plane will be picked up that close to the Pentagon or White House . Anything that seems to be in the immediate vicinity of harming the pres. will be viewed as a threat. In this day and age you can bet that at least 2 fighter jets will be scrambled to ess the threat. If they determine that it is even a remote possibility that they are seeking to do this they will be shot down or talked down. Regardless of public opinion the president, like him or not, is the most valuable man in our country. And he will be protected at all cost. BTW, 2 American pilots vs. 1 Korean escort= 1 dead Korean in almost anyone book. I doubt very seriously there are 2 pilots that would go down without a fight. You might get under the radar at sea but a plane the size of a C-130 would be spotted immediately by current and former servicemembers and there would be an alert put in place. Trust me most former servicemembers can recognize the aircraft by name, sound, size and even by country of origin. Just because people think Uncle Sam has a bunch of brainwashed kids doesn't mean they weren't taught to recognize a threat. I'm also sure that between the US Navy & the US Coast Guard that one or both would pick them up. They do have ways of catching drug smugglers that are using similar tactics.
