Swissair Flight 330 crashed on February 21, 1970, due to a terrorist bombing. Approximately nine minutes after take-off from Zurich, a barometric-triggered bomb detonated in the aft cargo compartment. The explosion caused a loss of cabin pressure and started a fire that filled the cockpit with thick smoke, making it nearly impossible for the pilots to see their instruments. Despite their heroic efforts to turn the Convair CV-990 Coronado back to Zurich for an emergency landing, the aircraft suffered a total loss of electrical power and crashed into a wooded area in Würenlingen, Switzerland. All 47 people on board were killed. The attack was attributed to the PFLP-GC, a Palestinian splinter group, who reportedly targeted the flight because it was carrying mail and passengers destined for Israel. This tragedy remains a pivotal moment in aviation history, leading to the first major international push for significantly stricter airport security and cargo screening protocols.
