While walking down the mall last night (about 7:37 PM Eastern), I saw a large jet on approach to DCA. It appeared to be all painted in Steelers colors and had the Steelers logo on the tail.
I could not make out the tail number, nor could I match it up with anything obvious (in terms of arrivals) on FlightAware. Any ideas? Was it a team jet or a jet owned by the Steelers owner, or was it a regular airliner dressed up for some reason?
