Friday's papers reflect on what they believe are the details of the suspected plot to blow up passenger planes.
Under the front page headline "Bottle Bombers", the Sun says suicide bombers wanted to detonate liquid explosives to kill 4,000 people.
The Daily Express reports that it is thought the suspects were within 48 hours of carrying out their suicide missions before being foiled.
The Daily Mail poses the question "Did They Foil A New 9/11?".
The papers discuss the US connections to the suspected plot.
The Guardian reports that officials in the US believe the plot involved targeting American cities including New York, Washington and San Francisco.
The Mail says eight American cities were the focus of the plans with three aircraft to be destroyed in each wave of three separate attacks.
In the words of the Daily Telegraph, the tactics would have caused "maximum loss of life".
'Difficult to detect'
Many of the newspaper reports on the alleged plot look at the catastrophic consequences of liquid explosives.
Security experts tell the Financial Times that although terrorists find such explosives "tricky to handle", they are nevertheless "difficult to detect".
The Mirror points out that in innocent looking plastic containers, "liquid hydrocarbon fuel could easily pass as mineral water".
The Independent says X-ray machines are "useless in the face of such devices".
The people suspected of the plot provide the papers with much material.
In particular, a young man who the Mirror claims converted to Islam only six months ago, "after turning his back on a life of drugs and booze".
Among the others being held, the paper says, are "a university student, a builder, a pizza worker, a businessman and a dad-to-be".
The Telegraph says they "include middle-class, well-educated young men".
