Planes crashed into the upper floors of both World Trade Center towers minutes apart today in a horrific scene of explosions and fires that left gaping holes in the 110-story building. 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. In Washington, officials said the FBI was investigating reports of a plane hijacking before the crashes. 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.
