At the 6:31 mark you can see the F-15EX do its version of the Dojo Drift, a maneuver made famous by the F-35's flight demonstration crew. It performs a 120 degree turn in 3 seconds as the tail slides around. A maneuver impossible in the old F-15 due to its old hydraulic manual flight control system.

@tonygryboski8593 The F-15A did not have digital fly by wire, the F-16 was the first US fighter to have that but back then the computers were not advanced enough to control the aircraft in post stall maneuvering like they are not.

@tonygryboski8593 I think the problem is my inability to communicate effectively what I am trying to say. The F-15's flight control system was mechanical and pilot inputs were executed by hydraulic actuators. While it had things like CAS, AFCS, PRAD, and PTC these systems helped make the F-15 easier to fly. A full digital fly by wire flight control system on the F-35 for example the pilots stick is not connected to any of the flight controls. Instead a computer interprets what the pilot it trying to do with stick and rudder inputs. This allows for far greater maneuverability than the F-15's old flight control system would allow. Take the Dojo drift maneuver https://www.youtube.com/watch?v=UIHgnmdJ7JM The F-35's flight control system allows the aircraft to effectively fly a maneuver that would result in a departure from controlled flight in an aircraft with a mechanical flight control system.
