Sweat put down workers faces as they lined up for bottles of water, or sat under a tent with plates of pasta, pizza or a chicken sandwiches, while rescue pet dogs who were also relaxing looked their way. Others waited to get out of their equipment, smelling of fire and whatever pollutants still burned in the rubble. A small drone flew overhead as a priest strolled over to one exhausted-looking firemen and offered him a hug. For some, the scene conjured the after-effects of the 2001 terrorist attack on the World Trade Center in New York– something rescue employees learn about when they are taught about how to handle “a pancake collapse,” in which structure floors fall on top of one another.
