RHINEBECK, New York - Chelsea Clinton's wedding along the Hudson River will be under a no-fly zone.

The Federal Aviation Administration says local airspace will be restricted from 3pm Saturday to 3.30am Sunday (local time).

Clinton, the daughter of former President Bill Clinton and Secretary of State Hillary Rodham Clinton, will wed investment banker Marc Mezvinsky on Saturday evening in Rhinebeck. That's about 150km north of New York City.

FAA spokesman Jim Peters said today that decisions to restrict air space are made in consultation with other federal agencies. He could not confirm whether the Secret Service requested this one.

The FAA website says the restriction will be in place for "VIP (Very Important Person) Movement" but did not elaborate.

Security experts said the list of people qualifying for VIP status is limited to the highest of government officials - and that former President Bill Clinton and Secretary of State Hillary Rodham Clinton would qualify.

"It's good policy. You do have a former president showing up at a big event; it's only prudent that the FAA does this," said Michael Boyd, airline consultant and president of the Boyd Group International in Evergreen, Colo.

There were no indications that access to the Hudson River near the estate was being similarly restricted. Sgt. Michael Dampf of the Dutchess County Sheriff's marine patrol said it planned no operational changes on Saturday and had not received any restriction notices from the US Coast Guard.

Amtrak, which runs passenger trains along the river, expected no changes in service on Saturday, said spokesman Cliff Cole.

On the television programme The View today, US President Barack Obama revealed he hadn't been invited to Chelsea's wedding.
