Looking @ Davis Monthan AFB from the other side of Tucson (Catalina Range through a spotting scope so I can't get a better image) & I see a line of DC10s (used for refueling Im guessing) but does anyone know what the really big plane (top left) facing the opposite direction is? Thanks.

I think that's a C-17, but I'm no expert.

I don't see winglets but didn't want to get excited again.
