Yeah they did. From the story I heard working there...The money behind Pan Am comes from Mellon (as in Mellon Banking). Tim Mellon is a long time pilot who promised his dad (who was friends with Juan Tripp - the guy that started Pan Am) that he'd get Pan Am flying again. He partnered with Dave Fink who is the VP of Guilford to run the airline. Unfortunately, running an airline is not like running a railroad and the airline stopped operation in Sep '02. (I have a theory why the airline failed under the leadership of a railroad minded manager, but it's a theory only.) They've since started again flying three B727 on charter operations. From the internet reports I've read, Fink is using the Pan Am name to bolster the flagging Guilford name. Over 200 boxcars are slated to be painted in the Pan Am colors, and so far this one engine. Still, it would be pretty cool watching a Pan Am diesel run the rails.
