Hazardous materials experts change into biological resistant suits before inspecting a suspicious box at Sydney International Airport October 14, 2001. Early reports were that the material was a white powder, similar to powder reportedly found in letters sent in the United States to people who appear to have contracted anthrax in the weeks after the September 11 attacks. [A spokesman for the airport operators later said the box had been left near some check-in counters by airport workers and contained coupons or vouchers and staff had found some material on it that they felt uncomfortable handling.]
