6、NEW YORK －Helicopters continued to take off and land Monday, giving tourists a bird’s-eye glimpse of the Manhattan skyline, even as tour operators and city officials reacted to new warnings issued by federal officials that al-Qaeda might use helicopters in terrorist attacks.

Some heliport and helicopter operators said they might take additional security precautions because of warnings about helicopters being used as weapons by terrorists.

But they emphasized that they have been on heightened alert(警觉) since the Sept. 11 attacks.

The FBI and the Department of Homeland Security issued three bulletins Friday to 18,000 law enforcement agencies nationwide warning about the possible use of helicopters, rental vehicles and rented storage facilities by terrorists.

One bulletin said that “although there is no credible, specific evidence supporting use of helicopters in an aerial(空中) attack in the United States, the threat cannot be discounted."

A second bulletin noted that limousines(大轿车) should be more closely examined because they "have larger storage capacity than regular passenger vehicles." It added that with their aura of importance, limousines may be allowed where the public would not.

Still, much attention is on New York, where financial institutions were recently the focus of a new terrorism alert and the Republican National Convention will take place at the end of this month.

New York City has three heliports used by companies that provide aerial tours. One of the tour operators, Liberty Helicopters, said in a written statement that it was contacted last week by the FBI-NYPD Joint Terrorism Task Force.

No details were given on what was discussed.

The statement said that since Sept. 11, the company has upgraded its security procedures to include physical screening and a check of passenger identification. It also does not allow sightseers to carry any personal luggage on helicopter tours.

One company that ferries individuals into New York City on New Jersey-based helicopters said that police seem to have stepped up their scrutiny in past days.
