On the morning of July 4, 1989, alarm bells blared at Soesterberg Air Base in the Netherlands, home of the US Air Force’s 32d Tactical Fighter Squadron.
Within minutes, a pair of armed F-15 Eagles, manned by Capts. J.D. Martin and Bill “Turf” Murphy, were launched on a scramble order. Their mission was to intercept what appeared to be a lone fighter making a beeline from Soviet-controlled airspace into Western Europe.
Though the Cold War’s end was seemingly not too far away, tensions still ran high between the two sides of the Iron Curtain, and any incursion by an unidentified aircraft would need to be responded to swiftly.

As JD and Turf were vectored in on the aircraft, now identified as a Soviet MiG-23 Flogger supersonic fighter, ground controllers notified them that all attempts to contact the inbound jet had failed and the intentions of its pilot were unknown and potentially hostile.
When they got close the the Flogger, the two Eagles were primed and ready to shoot down their silent bogey if it didn’t respond and carried on its flight path. But when the two F-15 pilots closed in on the aircraft to positively identify it, they noticed that the pylons underneath the Flogger — used to mount missiles and bombs — were empty.
By then, the Flogger was firmly in Dutch airspace, casually flying onward at around 400 mph at an altitude of 39,000 ft.
