NU Online News Service, Sept. 15, 2:08 p.m. – Smoke is still rising from the remains of the Manhattan World Trade complex this afternoon, but the smoke is whiter than it used to be, and authorities are saying that may be a sign that new fires are abating.
Rescue workers are still trying to find survivors, but the rain that fell Friday has given the debris a consistency similar to that of soft concrete, making excavation work more difficult.
The rain did help people in other parts of Manhattan breathe more easily, by washing some of the dust and smoke out of the air.
Meanwhile, fighter jets and military helicopters patrolled overhead as airports returned to limited service.
