As a former RC-135/KcC135/E-3 AWACS Instructor Pilot I don’t think you or that Chinese fighter pilot understand the physics involved in formation flying with large aircraft. There is a bow-wave that forms off of the nose of any aircraft, and in the case of a large aircraft it can be very dangerous for both aircraft if a smaller aircraft encounters it. We once had a mid-air collision when an F-4 Phantom was in almost that exact position with a KC-135 (they were violating procedure and the F-4 had come in close for a photo) and when the F-4 encountered the bow wave it threw the F-4 underneath the the KC-135 and the vertical tail struck the underside of the KC-135 below the cockpit. 14 inches of the vertical fin of the F-4 were ripped off and it put a large gash in the KC-135. Miraculously both aircraft survived the mishap.
