How long did it take to extinguish all the flames from the 9/11 attacks on Ground Zero?
It took firefighters 100 days to extinguish all the fires ignited by the attacks in New York. For months, acrid clouds of smoke from the site could be smelled several miles away in Brooklyn and upper Manhattan. The fires, fueled by documents and office furniture, had been so strong they needed a near-constant jet of water sprayed on them. It took until May of the following year to clean up the 1.8 tons of debris left at Ground Zero from the attacks on September 11th. The cost of cleaning up the debris was estimated as $750 million. We will never forget.
The correct answer is 100 days.
