The walking wounded were led along tracks after the attack
Police are investigating whether the suicide bomber who killed 26 people at King's Cross had used flight simulators to practice flying passenger planes.
A "Jermaine Lindsay" is listed as a "pilot" with a web-based group who use virtual copies of airline schedules.
He listed his nearest major airport as Heathrow and clocked up 30 hours in two months with SimAirline.net.
The Press Association alerted police to the finding and it is believed they are trying to see if this was the bomber.
A pilot roster for SimAirline.net, discovered by PA, showed a Jermaine Lindsay joined the group in December 2003.
The club has hundreds of members and most use Microsoft Flight Simulator, a realistic PC-based programme.
The 9/11 Commission in the US concluded last year that those responsible for flying the planes into World Trade Centre and Pentagon had used PC-based flight simulators for training.
Police have been investigating possible links between the 19-year-old bomber Lindsay, whose name has been variously spelt Germaine and Jermaine, and flying simulators after being handed a document by PA.
However, a Scotland Yard spokeswoman said they would not comment on individual lines of inquiry.
SimAirline.net operates a virtual copy of scheduled flights by 22 carriers, including British Airways, Virgin and Air Canada.
The group's pilots log their trips, stick to timetimes and "fly" the type of aircraft used by their particular airline.
