I snapped this shot of a McDonell Douglas DC-10 a few weeks ago, it was parked directly behind the Las Vegas Harley Davidson store on the south end of Las Vegas Boulevard at McCarran International Airport. I was in the store just eyeballing the eye candy inside. There’s nothing like a hog under your buns! I love these older aircraft. This unit looks to be a, or was an Extender that the military uses for refueling and other things (I think) as it was all gray. This link has better information. Not a great shot but iColorama tricked it up a bit.
