We have a very large version of that at College Park Airport, in the pilots briefing area. Interceptions used to be a monthly event, now, not so much, as the FAA personnel caution flight plan filers that the need to have a clearance to fly in. The first few years, the FAA guys and gals were oblivious to the restrictions, and accepted flight plans to the inner airports routinely.
Nothing funnier than a couple of F 16's trying to fly alongside a C 150 and give him hand signals to follow them to the designated landing field.
NOT POLITICAL, HAPPENS REGARDLESS OF WHO IS PRESIDENT.
Returning from a lunch hamburger at Easton, we were held outside the defense perimeter until a single engine Cessna was successfully intercepted, then ordered to fly to Fort Meade, land, and wait for a TSA officer to drive down from BWI to search the plane, pilot (Me) my wife, to be sure we were not part of a conspiracy to attack Washington in our Cessna 172. Fortunately, in accordance with my learn from experience practice, I had emptied my pockets of a pen knife and my wife's pocket book of her nail file, so nothing was seized. The TSA lady gave me a secret 4 digit number which allowed me to file a flight plan from FME to CGS , but refused me permission to use her government cell phone to file that plan. "It is a Government phone, that would be private use"! Long walk to the FBO, file the plan, and fly 0.2 TT to home base.
Total TT, 0.9, total elapsed time, over 2 hours.
These intercepts are mostly a joke. The poor jokers who fly into CGS with their home built to visit the College Park Aviation Museum get on the ground before the jets get airborne, so they circle overhead until the police arrive to take the guy in custody.
When the whole thing is done, the local pilots find someone qualified to fly whatever the visitor flew in, and fly him out, or if a single seater, fly the plane out, and give him a ride to where his plane is, so he can go home. The license suspension is not immediate, but he is not authorized to fly inside the perimeter.
