Southwest 737-700 N7715E starting its climb out of Pittsburgh.

KC-135T of the 171st ARW about to make contact with a USN E-6B Mercury command post aircraft over AR-218 in Pennsylvania. Although similar in appearance, the KC-135 (717) and E-6 (707) are quite distinct airframes, with the E-6s being the last new-build 707 models.

Caught this shot last year of Southwest's "Nevada One" special scheme Boeing 737.

This one was actually floating on a layer of clearish water atop that vegetation mat, and was not walking upright. At least, I don't think so :-)
