Skylift
The Skyhook is a very large heavy-lift helicopter. It resembles a S-64 Skycrane/Aircrane.
It is seen in the debut trailer of The Ballad of Gay Tony. It is seen carrying a train car with Luis hanging behind the car.
It is also involved in one mission where Luis drops on to the top of a moving subway train from a bridge and unhooks one of the train cars for a collector which is then airlifts the train car away to safety.
