TOKYO — Suspects in the terror plot uncovered in the United Kingdom were planning on destroying multiple flights using liquid explosives and electronic devices, Michael Chertoff, secretary of the Dept. of Homeland Security, confirmed in a press conference.

Sources have told CNN and other news outlets that electronic detonators may have been disguised as automobile remote control key fobs.

Chertoff also said that additional sky marshals are being sent to the U.K. to provide additional protection on flights between the U.K. and United States.

Interesting advice from TSA Administrator Kip Hawley:

1. “De-clutter your bag” so that TSA screeners have a clear view through the X-ray machine.

2. “Enjoy your trip.”

Update: Chertoff confirmed U.S.-flagged carriers were the target in the late-stage planning by the suspects, but did not name specific airlines.
