Airline plot involved liquid explosives

LONDON - British authorities said Thursday they had thwarted a terrorist plot to simultaneously blow up several aircraft heading to the U.S. using explosives smuggled in carry-on luggage. U.S. Homeland Security Secretary Michael Chertoff said the terrorists planned to use liquid explosives disguised as beverages and other common products and detonators disguised as electronic devices. Officials raised security to its highest level in Britain and banned carry-on luggage on all trans-Atlantic flights. Huge crowds formed at security barriers at London's Heathrow airport as officials searching for explosives barred nearly every form of liquid outside of baby formula.
