This is the warm up then lift off of an erickson sky crane. It was operating out of the central cascade mountains in washington state, in the us. This helicopter is for fire fighting, and can carry 3,000 gallons of water or retardant to a fire - it's enormous. There are only 31 sky cranes in existence, and in august of 2018 we have two of them fighting fires in our surrounding mountains.
