Steelers jet at DCA?

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?

It may have been a US Airways A319. Did it look like this: airliners.net/photo/US-Airwa … 1462895/M/

Yep, it sure did. I could only see the back because of the angle I was viewing it from. I bet that’s it.

Thanks!
