Planes crash into World Trade Center

NEW YORK (AP) -- An aircraft crashed into the upper floors of one of the World Trade Center towers Tuesday morning, and black smoke poured out of two gaping holes, witnesses said. Shortly afterward a second plane hit the other tower.

There was no immediate word on injuries or fatalities in the twin disasters, which happened shortly before 9 a.m. and then right around 9 a.m.

The towers were struck by bombers in February 1993.

"The plane was coming in low and ... it looked like it hit at a slight angle," said Sean Murtagh, a CNN vice president, the network reported.

Large holes were visible in sides of the 110-story buildings, landmark twin towers.

The tops of the twin towers were obscured by the smoke.

Thousands of pieces of what appeared to be office paper came drifting over Brooklyn, about three miles from the tower, one witness said.
