Security stepped up at Indy for US GP

The event looked to be under threat following the tragic terrorist attacks in America last week and there were concerns that world champion Michael Schumacher may not attend the race earlier this week.

However, preparations are proceeding as normal and all the teams and drivers are expected to attend, along with a full complement of security men and police officers.

Following last Tuesday's air attacks on New York and Washington, America is under extremely tight security guidelines. The boxes of equipment for all 11 Formula 1 teams are being flown to the US via either Holland or Luxembourg in order to be X-rayed.

Similar measures are being taken at the speedway itself with its security plan, which has been put together with the help of the federal law enforcement authorities, being reviewed for next weekend's race.

"While we are very saddened by recent events, we continue to plan and work for what we expect will be a successful, exciting event," said Indianapolis president Tony George. "President Bush has urged Americans and the world to proceed with everyday life, and we are doing so with deep respect for those affected by last week's tragedies."

Despite doubts over whether the US race should go ahead, other national American sports, such as Major League Baseball and the National Football League have already returned to their usual schedules.

Formula 1 testing, which is taking place at Silverstone, Estoril, Mugello and Fiorano this week, is not expected to be affected by the earlier departure date for America caused by the heightened security.
