UNDATED (AP) -- Planes have crashed into several U.S. sites, including the World Trade Center in New York City, the Pentagon, and a farm field in Pennsylvania. "The two explosions were incredible and at the point of explosions all you could see outside were personal belongings and office supplies raining outside," said Bob Rendine, an American Stock Exchange spokesman, whose office is down the block from the NYSE. "We're staying here. We think it's safer to stay inside then go outside at this point."
Planes were grounded nationwide after the report that there may be more hijackings. "We're like everyone else, in shock," said Carol Windham, a spokeswoman at Birmingham International Airport in Alabama.
Heightened security went into effect at government and corporate offices nationwide, from the Army's main germ warfare defense laboratory in Frederick, Md., to city offices in Colorado. "I don't think there's any place in America right now that's not at risk," said Andrew Hudson, a city spokesman in Denver, where emergency preparedness officials gathered in the basement of City Hall.
In Philadelphia, dozens of people gathered in a hotel lounge to watch television coverage. A visitor from Texas wept. "I can't believe what I'm seeing. I never thought I would see anything like this in my lifetime," said 20-year-old Beverly Evans of Dallas. "How can we stop something like this from happening?"
