September 30

In the early hours of 30 September 1888, two victims of Jack the Ripper were discovered in Whitechapel, London. Elizabeth Stride was found with her throat cut but without the mutilations seen in other killings, leading investigators to believe the killer was disturbed. Less than an hour later, Catherine Eddowes was found in Mitre Square with severe abdominal mutilations, marking the fourth canonical Ripper murder. These gruesome crimes intensified public fear and media frenzy, as the killer eluded capture. Police efforts were hampered by limited forensic techniques and surging crowds of onlookers. The double event on this night underscored the brutal nature of the unknown assailant and deepened the mystery surrounding his identity. Jack the Ripper’s reign of terror would continue until November 1888, leaving an enduring imprint on London's criminal history.

On September 30, 1978, 26-year-old Finnish criminal Aarno Lamminparras hijacked Finnair Flight 405 shortly after takeoff from Oulu Airport. Armed with a pistol, he demanded to speak with the Finnish prime minister and threatened to blow up the aircraft. Crews and passengers were held overnight on the tarmac before authorities agreed to his demands for money and a tribute fanfare. The incident ended peacefully when Lamminparras surrendered in exchange for the release of the hostages. This high-profile event prompted reviews of aviation security protocols in Finland and across Europe. The hijacking remains a dramatic chapter in Finland’s aviation history and underscored the global rise of skyjacking in the 1970s.
