![]() | Narrative and Notes (Reliable) | Following the arrests of suspected terrorists in the United Kingdom in connection with a plot to bomb transatlantic airliners, U.S. Homeland Security Secretary Michael Chertoff announced he was raising the threat level to "red" for U.S.-bound transatlantic flights originating in London and "orange" for all other flights. It was the first time Homeland Security implemented a "red" level threat, its highest. The British similarly raised their treat level to "critical." The plot appeared to involve the use of liquid explosives to be smuggled on board planes; aviation security personnel were confiscating liquids from many air travelers. Authorities described the plot as close to execution. The U.S. lowered its UK-oriented threat to "orange" on Aug. 13, matching it with the rest of the threat to airlines.1,2 | |
