A Swedish Douglas DC-3 aircraft, designated as SN 29180, was engaged in a routine reconnaissance flight over the Baltic Sea. During this operation, the plane inadvertently crossed into Soviet-controlled airspace. The Soviet military, vigilant about unauthorized intrusions, deployed a MiG-15 fighter to intercept the aircraft. As the MiG-15 approached, it opened fire on the unarmed Douglas DC-3, resulting in the plane being shot down near the island of Gotland. All aboard the Swedish aircraft perished in the attack, marking a disturbing escalation in Cold War tensions between Eastern and Western blocs.

The incident sparked a wave of outrage and condemnation in Sweden and internationally. Swedish officials were alarmed at the blatant violation of international norms regarding neutral airspace and the rules of engagement. The Swedish government took the matter to the United Nations, demanding accountability and expressing deep concern over Soviet military aggression, which threatened the safety of civil aviation. The Soviet Union, in contrast, downplayed the incident, asserting that the aircraft was conducting espionage.

This event contributed to the growing polarization of global politics in the Cold War era. It underscored the risks faced by civilian aircraft in contested airspace and the delicate balance of power during this tumultuous period. The Swedish-American friendship was also tested, as Sweden sought support while trying to maintain its policy of neutrality amidst a backdrop of superpower conflict.
