September 14

On September 25, 1978, Pacific Southwest Airlines Flight 182, a Boeing 727 approaching San Diego’s Lindbergh Field, collided with a Cessna 172 training aircraft over the North Park neighborhood. The jet plunged into a residential street, killing all aboard both planes and seven people on the ground. The disaster and the NTSB investigation that followed exposed the limits of “see‑and‑avoid” separation in busy terminal airspace and helped push the industry toward airborne collision‑avoidance systems.

On September 5, 1977, in Cologne, West German industrialist Hanns Martin Schleyer was abducted by a Red Army Faction commando. The ambush left his driver and three police bodyguards dead. Weeks of hostage negotiations, a linked international hijacking of Lufthansa Flight 181 and the contested deaths of imprisoned RAF leaders culminated in Schleyer’s execution; his body was found on October 19, 1977. The episode became the defining climax of the "German Autumn," reshaping West German politics, security policy, and public memory.

On September 19, 2021, a fissure opened on the southern slope of the Cumbre Vieja ridge on La Palma, Canary Islands, sending rivers of lava down toward coastal towns, forcing thousands to flee, and reshaping the island’s western flank. Over 85 days the eruption buried villages, created new coastline, and left a landscape and community facing years of recovery.
