Watched a Caribou Taxi in many years ago next to where I was parked at a small drome thinking WTF he'll corner himself for sure and jam me in too! The noise was deafening! Then I noticed the rear ramp come down and a Aileen looking guy walked down the ramp tethered to the plane via his helmet (reminded me of "Close encounters of the third kind") and the big lumbering noisy bird backed up right into a tight spot! Never seen that, well I had done it a few times in the plane I was driving but that Caribou looked so ugly cumbersome!?
