I've seen this done before. When Bush was in office, he visited the local area. Unknown to a local pilot in his private plane, the no-fly zone around Bush was violated. The pilot was intercepted by a pair of fighters who did a very strange maneuver to escort the Cessna away. It looked like a controlled stall, the nose of the fighters were turned up very high, and they were essentially hopping next to the private craft. It was very strange to see.
