While I was on short final into KFHU (Fort Huachuca, Sierra Vista Arizona):
"Shadow-1 at runway 26, ready to take off."
"Shadow-1, hold short for landing traffic."
I then looked over at the holding aircraft and noticed that it was a Military UAV, an Unmanned Aerial Vehicle. This being the first one I'd ever seen, I struggled between landing my plane and looking at the UAV. Landing the plane finally caught my attention.
After landing, while on rollout, I overheard:
"Tower, was that an unmanned airplane I just passed?"
"NXXXXX: Yes, it was."
"There is actually a man sitting somewhere ... ."
