A Sunday Review essay on April 12 imprecisely described a cap from the pilot wheel of the Enola Gay. The cap — which was said to have been removed from the plane in 1947 by Robert John Rich Sr., an Air Force pilot whose granddaughter recently took a class with the essay’s author, prompting its rediscovery — had a Boeing emblem. But it was not the original cap; that cap, still missing, most likely had the logo of the Martin Aircraft Company, which built the plane under a contract with Boeing. (A curator at the Smithsonian, which located a vintage Boeing cap when it restored the plane in the 1980s, said he learned of the original Martin cap when contacted by a reader of The Times.)
The final seizure of the city was set in early February 2000, when the Russian military lured the besieged militants to a promised safe passage. Seeing no build-up of forces outside, the militants agreed. One day prior to the planned evacuation, the Russian Army mined the path between the city and the village of Alkhan-Kala and concentrated most firepower on that point. As a result, both the city mayor and military commander were killed; a number of other prominent separatist leaders were also killed or wounded, including Shamil Basayev and several hundred rank-and-file militants. Afterwards, the Russians slowly entered the empty city and on February 6 raised the Russian flag in the centre. Many buildings and even whole areas of the city were systematically dynamited. A month later, it was declared safe to allow the residents to return to their homes, although demolishing continued for some time. In 2003 the United Nations called Grozny the most destroyed city on earth.
