I agree, where's the equipment. Even if we don't have a lot of "blackhawks", we have a lot of other kinds of helicopters
I expect that it isn't very safe flying helicopters during a hurricane. Because of that, they probably couldn't do anything about the initial levee breach. By the time the storm has subsided enough to allow helicopters to be used, it was probably too late to control the flooding.
there was no plan, not at the city level, not at the state level, and not at the federal level, to get the people out of harms way before the event, or even to deal with the aftermath.
There is no point in planning, unless you are going to actually do something about it. To do something about it requires spending money. And that would make you a "tax and spend" liberal. The "give huge tax breaks to the rich and saddle our children with enormous debt" conservatives could never consider such a thing as planning ahead.
