Here is how an F-15E Strike Eagle from RAF Lakenheath went supersonic over Wales, UK, during air combat training with other aircraft of the 48th Fighter Wing.
Courtesy of Plane Plotter you can now see the F-15E breaking through Mach 1 at an estimate speed of 680MPH (calculated by MLAT – Multi Lateration of Mode-S transponder signals).
Watch AE0000, a spoof hex code for flight previously using callsign “Pyro31”. The aircraft maneuver, accelerates (543 kts is the highest value you can see in the animation) then it “trickled” through supersonic speed.
As the plane made off for the corridor the pilot changed the callsign to “Rumble31” (unfortunate use of such callsign in this case, but quite common during such tactical events).
It managed to shake some ceiling tiles down in a supermarket.
Still, probably the most exciting thing to happen in Aberystwyth for a few years.
Really F15 is transponder mode S, ADB-S installed?
Mode-S transponder. Position was determined through MLAT
