7/7 Conspiracy main-stream again

Central to the puzzle is which train the four Muslims caught from Luton to London on the morning of the bomb blasts - bearing in mind that the three separate Tube explosions at Edgware Road, Aldgate and King's Cross occurred together at exactly 8.50am, followed by the red bus an hour later near Tavistock Square.

The report insisted that the bombers acted on their own, constructing explosives from chapatti flour and hair bleach mixed in the bath at a flat in Leeds, Yorkshire, where all four had family and friends.

It concluded that the Muslim bombers were not controlled by a terrorist mastermind, but inspired by Al Qaeda ideology picked up on extremist websites.

But families of the dead victims and an increasing number of 7/7 survivors claim there are inconsistencies and basic mistakes in the official accounts that need explanation.

And they are demanding a full public inquiry to answer key questions about what the Intelligence Services and the police did and did not know before the bombings.

The official reports said the bombers got on the 7.40am train from Luton which would have arrived at King's Cross in good time for them to board the Tube trains.

However, the 7.40am train never ran that morning. It was cancelled.

The Government has since corrected this information - but only after the error was raised by survivors - saying the bombers actually caught an earlier train, the 7.25am from Luton, for the 35-minute journey to King's Cross. It was due to arrive in the capital at 8am.

Yet this throws up more questions than it answers. For this train ran 23 minutes late because of problems with the overhead line which disrupted most of the service between Luton to King's Cross that morning. It arrived in London at 8.23am, say station officials.

According to the July Seventh Truth Campaign - another group calling for a public inquiry - this again places the official version of the bombers' travelling times in doubt.

A still CCTV photo of the four bombers arriving at the station in Luton is the only one of the four men together on July 7. Controversially, no CCTV images, either still or moving, of them in London have ever been released.
