I flew into Marana Pinal Airpark (MZJ) VFR last month and noticed the "Sharko" 767-200 parked there. Additionally I saw a plain 747-400 with a solid blue tail and the name Aero Sur on the fuselage. (Although I don't see any pictures of that one on Airliners.net...)
So, with two aircraft from their fleet parked at MZJ, where are the rest? I'm particularily interested in the 747-400 Bull.
