PauknAir Flight 4101
On 25 September 1998 PauknAir Flight 4101, a British Aerospace 146 regional jet flying from Málaga to the Spanish enclave of Melilla, descended below published approach minima in instrument conditions and struck rising terrain on the slopes of Mount Gurugu short of the runway. All 38 people on board were killed. The accident was later classified as a controlled flight into terrain (CFIT) and prompted renewed emphasis on approach procedures, crew resource management, and terrain‑awareness equipment. Read more

Pacific Southwest Airlines Flight 182 mid‑air collision
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.

Second Battle of Champagne
On the morning of September 25, 1915, French Fourth and Fifth Armies launched a major offensive across the Champagne plain against German 3rd and 4th Armies. Intended as a coordinated autumn push alongside operations in Artois, the attack produced local penetrations but no strategic breakthrough. Over weeks of grinding assaults, artillery duels and counterattacks, the campaign inflicted heavy casualties on both sides and helped reshape artillery and infantry tactics in the years that followed.

Explosion of the French battleship Liberté
On the morning of September 25, 1911, the pre-dreadnought battleship Liberté exploded at the Toulon naval basin. The blast — almost certainly caused by the spontaneous ignition of degraded Poudre B propellant in a forward magazine — destroyed the ship’s bow, killed and wounded hundreds, damaged nearby vessels and dockworks, and forced the French Navy to confront the hidden dangers of early smokeless powders.

Soviet invasion of Poland (1939)
On September 17, 1939, the Red Army crossed the eastern border of the Second Polish Republic — moving into territories that are now western Ukraine, western Belarus and parts of Lithuania — announcing it would “restore order” after what Soviet authorities described as the collapse of the Polish state. The advance followed the secret division of Eastern Europe in the Molotov–Ribbentrop Pact and coincided with a German invasion from the west, opening a painful chapter of occupation, mass arrests, deportations and political reordering whose consequences echoed through the war and into the Cold War era.

1928 Okeechobee hurricane (San Felipe Segundo)
A powerful Atlantic hurricane struck Puerto Rico on September 13, 1928 — Saint Philip’s Day — and then carved a path through the Bahamas to make landfall on Florida’s east coast on September 16–17, 1928. The storm wrecked crops, towns, and lives, but its deadliest legacy was the flood from Lake Okeechobee that overwhelmed low-lying settlements and killed thousands. The catastrophe exposed weaknesses in warning systems, racial and economic inequalities in relief, and ultimately drove federal flood-control work that reshaped the lake decades later.
