Thursday marks the one-month anniversary of the Sept. 11 destruction of New York’s World Trade Center, and the day will be marked by a morning memorial service to be attended by Mayor Rudolph Giuliani and the city’s fire and police commissioners. The service, to commemorate the 343 firefighters and 23 police officers lost when the World Trade Center’s towers crumbled, was one of several events planned to remember the thousands of people lost in the wreckage. “I have to admit, there’s not a day goes by I don’t get tears in my eyes,” Edwin Soseby, a member of the Army Corps of Engineers working at the site, told the Associated Press. On Wednesday the fragmented remaining steel skeleton of the Twin Towers had developed rust as the rubble continues to be cleared out. About 50 specially escorted mourners (relatives of those who perished) visited the area, some in tears, several clutching flowers. As of Wednesday, the number of people reported missing stood at 4,815, and 422 had been confirmed dead, 370 of them identified. Other than the service at the site, memorials and tributes planned for Thursday include a service at Park East Synagogue, a Mass by Franciscan monks and a benefit sponsored by The New Yorker magazine featuring readings by Woody Allen, John Updike and Arthur Miller.
