On the morning of July 4, 1989, a lone Soviet MiG-23 fighter jet lifted off from a Polish airbase, heading west. Its path would cross East Germany, breach the Iron Curtain, and soar over West Germany, the Netherlands, and Belgium before plunging into the French countryside. The story is astonishing enough—but it becomes even more surreal when you learn that the fighter jet had no pilot. It was flying on its own.

During the summer of 1989, the Cold War was in its final days, but the Soviet Air Force operated as usual. At Bagicz Air Base near Kołobrzeg, Poland, Colonel Nikolai Skuridin climbed into a single-seat MiG-23. A seasoned pilot, Skuridin had just returned from leave and was tasked with a test flight of this specific aircraft. The MiG-23, code-named “Flogger” by NATO, was a third-generation fighter-bomber with variable-sweep wings, in service since 1970. Powered by a single turbojet with afterburner, it could reach speeds of Mach 2.3 and had a combat range of 1,500 km (930 miles), extendable to 2,550 km (1,580 miles) with external drop tanks. This particular model was a MiG-23M, designed for air superiority.

Shortly after 9 a.m., Skuridin received clearance to taxi to Runway 25, heading west. Everything seemed normal as the MiG lined up for takeoff. With clearance granted, Skuridin pushed the throttle and lit the afterburner, generating 27,500 pounds of thrust. At 9:14 a.m., the MiG-23 left the runway on a heading of 250 degrees and began to climb. But just 29 seconds later, disaster struck. The afterburner failed, and Skuridin lost thrust abruptly. His aircraft began to lose altitude. With only 500 feet of altitude, he had to act fast. Believing he faced a complete engine failure and with the ground rushing up, he decided to eject. He pulled the ejection handle and was blasted clear.

As he parachuted safely, he looked toward the damaged MiG, expecting to see it crash into the ground or the nearby Baltic Sea. Instead of a fireball, he was stunned to see the MiG still flying—and even climbing in a stable trajectory. The afterburner had failed, but the engine itself was still running normally. The autopilot had engaged and was holding the aircraft steady, heading west. The MiG-23 was now on a direct course to leave Polish airspace and enter the airspace of East Germany, which was still part of the Soviet Union. So far, no international incident with NATO had occurred.

As it crossed East Germany, the MiG climbed to 40,000 feet and accelerated to 380 knots (700 km/h or 430 mph). The fighter was still in stable flight with plenty of fuel, heading straight for the Iron Curtain separating the Soviet Union from NATO. In minutes, the MiG-23 would be over West Germany.

At Soesterberg Air Base in the Netherlands, the 32nd Tactical Squadron of the US Air Force was hosting a barbecue for Independence Day when the alert siren blared. The pilotless MiG had entered West German airspace near Dannenberg and was detected by NATO radar. Consequently, at 9:42 a.m., two McDonnell Douglas F-15Cs were scrambled to intercept the intruder. At 10:02 a.m., the F-15 pilots approached the MiG-23 and couldn’t believe their eyes. No pilot. The cockpit canopy was missing. The ejection seat was gone. The aircraft was flying itself. “No pilot, no canopy. The ejection seat is missing from the aircraft. So I confirm the pilot appears to have ejected before the intercept.”

The F-15s followed the MiG as it headed toward Dutch airspace and potentially on to Belgium and maybe France. By then, an international crisis was brewing, with the governments and air forces of West Germany, the Netherlands, Belgium, and France on high alert. With the MiG now flying over Dutch airspace and given the high population density below, a decision was made not to shoot it down due to the very real risk of a ground catastrophe. Instead, the best course of action was to shadow it over Belgium to the North Sea and shoot it down there. Unfortunately, that plan wasn’t executed because, while the MiG was flying over Belgium, it finally ran out of fuel.

Once the engine stopped due to fuel starvation, the MiG-23 began a slow descent, losing airspeed. It still held a steady heading of 240 degrees. The two F-15 pilots followed closely, trying desperately to predict where it would crash and whether they should use a Sparrow missile to bring it down before it reached any populated areas. “Gradual descent. Oh, I think it’s out of fuel now. It’s just descending on autopilot. Still heading 240. Approaching a populated area now. I don’t know how it’s going out of control. We’ll have to shoot it down quickly. So I might end up using a reserve missile.”

In the end, they realized the MiG would avoid a major city center and was instead heading toward farmland near the town of Kortrijk when it ran out of altitude completely. The MiG-23 crashed. It smashed into a field just left of a farmhouse next to a highway. Tragically, although the MiG fell in rural farmland, it crashed directly onto a farmhouse, completely destroying it. Inside the farmhouse was one person, 18-year-old Wim Delaere, who was killed instantly.

Immediately after the incident, the angry governments of Belgium, the Netherlands, and West Germany lodged formal protests with the Soviet government. Despite the long time between Colonel Skuridin’s ejection and the crash, the Soviets remained silent and did not attempt to alert their NATO counterparts that one of their fighters was heading toward NATO territory. Two days later, on July 6, the Soviets finally issued a public statement about the incident. Colonel Skuridin offered a personal apology to Wim Delaere’s family for the loss of their son. Meanwhile, Soviet leader Mikhail Gorbachev also issued a statement expressing his sorrow and regret for the accident. He also agreed to pay compensation equivalent to 625,000, most of which went to the Delaere family. Due to improving relations between the US, NATO, and the Soviet Union, the incident was quickly forgotten, and an international crisis was avoided. Had this happened nearly a decade earlier at the height of the Cold War, things might have ended very differently. Of course, for the Delaere family, that day in 1989 will never be forgotten.

But the story of the runaway MiG-23 did not end with the crash in Kortrijk. In the weeks that followed, investigators from Belgium, the Netherlands, and West Germany pieced together the aircraft’s final flight path, and what they found raised uncomfortable questions about Soviet transparency. The MiG had flown for nearly an hour over NATO territory, and at no point did Moscow warn its adversaries. “They knew,” one Belgian investigator later told reporters. “They knew the plane was flying, and they said nothing.”

The Soviet explanation was that they had lost radar contact with the aircraft shortly after it crossed into West German airspace and assumed it had crashed into the Baltic Sea. But NATO radar operators had tracked the MiG continuously, and they found it hard to believe that Soviet ground control, with its dense network of early-warning stations in East Germany, could have simply lost the aircraft.

At the heart of the investigation was the question of why the MiG’s autopilot had engaged in the first place. Soviet engineers eventually concluded that when Skuridin ejected, the sudden loss of cockpit pressure and the violent jolt of the ejection sequence had triggered a fail-safe mechanism in the flight control system. The autopilot, designed to stabilize the aircraft in emergencies, took over and locked the MiG onto its last heading. With the throttle still set for cruise and the engine running normally, the aircraft simply kept flying.

What made the incident even more remarkable was the timing. The MiG’s route had taken it directly over some of the most heavily defended airspace in Western Europe. NATO’s integrated air defense system had tracked it from the moment it crossed the border, and yet the political decision not to shoot it down had been made within minutes. “We had F-15s on its wing for over half an hour,” a NATO spokesman later admitted. “But every time we considered firing, the risk on the ground was too high. We were lucky.”

Back in Poland, Colonel Skuridin faced a board of inquiry. He was cleared of negligence—the afterburner failure was traced to a manufacturing defect in the fuel control unit—but the psychological toll was evident. In a rare interview years later, he described the moment he looked up and saw his aircraft flying away without him. “I thought I was dreaming,” he said. “I was hanging in my parachute, and my MiG was climbing into the sky like a ghost. I knew then that something terrible might happen.”

For the Delaere family, the compensation from Moscow did little to ease the pain. Wim had been home alone that afternoon, preparing for a summer job he was due to start the following week. His parents returned from a shopping trip to find their home reduced to rubble and their son gone. The Belgian government later erected a small memorial near the crash site, a simple stone marker that reads, in part, “In memory of Wim Delaere, 1971–1989, taken from us by the winds of the Cold War.”

The incident also had a quieter legacy. In the months that followed, NATO and Soviet military officials held a series of previously scheduled meetings on airspace safety, and the MiG-23 affair became a case study in how quickly a technical failure could spiral into an international crisis. Some historians argue that the restrained response on both sides—NATO’s decision not to fire, and Gorbachev’s swift apology—was a small but significant sign that the Cold War’s logic of confrontation was beginning to break down.

Yet for the pilots who had shadowed the ghost jet across the skies of Western Europe, the memory remained vivid. One of the F-15 pilots, speaking on condition of anonymity, described the eerie silence on the radio as they followed the MiG toward its final descent. “We kept waiting for it to turn, to do something,” he said. “But it just kept going, straight and steady, like it had somewhere to be. It was the strangest thing I’ve ever seen in the air.”

As the MiG descended over the Belgian countryside, its fuel exhausted and its engine silent, it left behind a trail of unanswered questions that would linger for decades. The crash site was cleared within days, but the memory of the pilotless fighter that had crossed half of Europe on its own would not fade so easily.

The Soviet investigation, declassified years later, revealed a final twist. The MiG’s autopilot had a built-in safety feature: if the aircraft received no pilot input for a set period, it would automatically level off and maintain the last known heading. “The system was designed to save the pilot in case of incapacitation,” a Soviet engineer explained. “It had no way of knowing the pilot was gone entirely.” The aircraft had simply followed its programming, a ghost following orders no one had given.

In 1991, as the Soviet Union dissolved, the MiG-23 incident faded into the footnotes of history. But for aviation historians, it remains a chilling reminder of how close the world came to catastrophe. “If the F-15s had fired over the Netherlands,” one analyst noted, “we might be telling a very different story today.”

Wim Delaere’s parents never fully recovered. They moved away from Kortrijk, unable to pass the empty field where their home once stood. The stone marker remains, a quiet testament to a boy killed by a machine that flew itself.
