Ladbroke Grove rail crash
The Ladbroke Grove rail crash (also known as the Paddington rail crash) was a rail accident which occurred on 5 October 1999 at Ladbroke Grove in London, England, when two passenger trains collided almost head-on after one of them had passed a signal at danger.

Enrico Fermi Nuclear Generating Station reactor meltdown
The Enrico Fermi Nuclear Generating Station is a nuclear power plant on the shore of Lake Erie near Monroe, in Frenchtown Charter Township, Michigan on approximately 1,000 acres (400 ha). The plant is named after the Italian nuclear physicist Enrico Fermi, most noted for his work on the development of the first nuclear reactor as well as many other major contributions to nuclear physics. On October 5, 1966, Fermi 1, a prototype fast breeder reactor, suffered a partial fuel meltdown, although no radioactive material was released. After repairs it was shut down by 1972.
Eastman tunnel collapse
The Eastman tunnel, also called the Hennepin Island tunnel, was a 2,000-foot-long (610 m) underground passage in Saint Anthony, Minnesota, (now Minneapolis) dug beneath the Mississippi River riverbed between 1868 and 1869. During construction of the tunnel, on October 5, 1869, the river broke through the thin layer of limestone separating the river's bed from the tunnel. The rushing river scoured the tunnel, caving in parts of Hennepin Island and causing the earth supporting Saint Anthony Falls to collapse upstream. There was serious concern that the riverbed would crumble and reduce Saint Anthony Falls to a long set of rapids.
