That chopper is way too big for the bay on the ship. Bad even for Voyager
It was just the size of the plot, or all the Navy could spare for the film crew
That's the correct chopper, unlike in star fleet, they don't fly it into the bay. They land, fold up the blades and slowly roll it in. It's about as tight as a car in a one car garage.
Thank you for beating me to it.
