I was in an airport in Tucson (might've been on base, might not of been, can't recall, I spent a lot of time at both airfields) when one of these beasts landed and I couldn't look away, even though my animal brain was SCREAMING "THAT THING CAN'T LAND! IT'S GONNA CRASH INTO THE BUILDING AND KILL EVERYONE!!! RUN YOU FOOL!!!" It looks slow, but coming at you, it's a lot faster, lol!
