what would you have done if IAD had a TRW in progress? what would you have done if you couldn't get approach/departure control if you went around?
But, that is "what ifing" circumstances that did not exist that night.
If IAD had a TRW I would know a lot about it from having scoped it inbound to DCA. I would then consider BWI as well as IAD.
