The UFOs we want

In 2007, the US Department of Defense launched the Advanced Aerospace Threat Identification Program to collect sightings of ‘anomalous aerospace threats’ – in demilitarised English, Unidentified Flying Objects.

Last year, the New York Times and Washington Post got hold of some AATIP files, but it was disappointing to hear how conventional they sounded; UFOs haven’t changed much since the 1960s, defying physics and outrunning fighter jets.

At the Thames Barrier

Britain’s south-eastern coastline is low-lying, and faces relatively shallow waters. This makes London naturally vulnerable to the surges created when high tides coincide with North Sea storms, and shove water back up the Thames.

After a surge in 1953 killed hundreds of people across the Thames Estuary, the government commissioned a report on what to do from the mathematician and cosmologist Hermann Bondi. The result was the Thames Barrier at Woolwich, operational since 1983.
