As title says, the antenna masts in front of the UH-1D types are not visible from the pilot/copilot positions, nor are the windshield wipers

Note that in all the "shorty" variants, these antennae are visible from the inside. It is only the long-body "D" types that have these meshes missing.
The windshield wipers, however are not visible from the inside of any model.

It would be immensely awesome if these little antennae and wiper blades were to vibrate and wiggle with the rotor beat as the ones in the excellent new CH-47 do.

Those little details make it feel like such an authentic helicopter experience. I've been in one IRL, and indeed, everything vibrates aboard a chopper.
