Boeing 757-200 (00-9001)

Hey Aaron, I have seen some of these special mission all white 757's paint the tail number very discreetly on the wing-body fairing just aft of the wing in very faint very light grey. Very hard to see in certain lighting / shadow's. If you get another chance to get this close, you may want to check there. Thanks for posting!

Thanks John. I re-examined my images and she's devoid of any markings other than the US flag below windows 7 and 8 in the last bank of windows on both sides of the fuselage.

A similar looking plane, definitely a 757 without any markings, was doing pattern work at KALB earlier this week. It did not show up on either this site's tracking or the other site with "...24" in its name.
