They say them selves that contrails appear at high altitudes. The contrail in the video starts well below the helicopter and I don't know of a helicopter that can get to 25k feet. Even if it could a news copter would not be doing much good at that height. You also see what looks like another copter in to foreground of the video which really shows how low the contrail really did start. Also putting the origin of this thing over water really puts this as a military thing. I just hope it was our military that did it.
