Homeland Security Advisory System - Current Threat Level
September 10, 2007 The United States government's national threat level is Elevated, or Yellow.
The U.S. threat level is High, or Orange, for all domestic and international flights. Only small amounts of liquids, aerosols
and gels are allowed in carry-on baggage. See the Transportation Security Administration (TSA) website for up-to-date information
on items permitted and prohibited on airlines.
While there continues to be no credible information at this time warning of an imminent threat to the homeland, the department's
strategic threat perspective is that we are in a period of increased risk. The National Intelligence Estimate cited heightened
activity overseas and we're mindful of the recent arrests in Europe. There has also been an upward trend in propaganda tapes
and messages coming from al Qaeda and affiliated networks over the past year.

August 10, 2006 -- Statement by Homeland Security Secretary Michael Chertoff Announcing a Change to the Nations Threat
Level for the Aviation Sector - The Department of Homeland Security is taking immediate steps to increase security measures
in the aviation sector in coordination with heightened security precautions in the United Kingdom. For that reason, the United
States Government has raised the nations threat level to Severe, or Red, for commercial flights originating in the United
Kingdom bound for the United States. This adjustment reflects the Critical, or highest, alert level that has been implemented
in the United Kingdom. To defend further against any remaining threat from this plot, we will also raise the threat level
to High, or Orange, for all commercial aviation operating in or destined for the United States.
July 7, 2005 (11:45 a.m. EDT) -- Homeland Security Secretary Michael Chertoff announced a targeted raise in the threat
level. In light of todays attacks in London, the United States Government is raising the threat level from Code Yellow &
or Elevated to Code Orange or High targeted only to the mass transit portion of the transportation sector. This only includes
regional and inter-city passenger rail, subways and metropolitan bus systems. We are also asking for increased vigilance in
