A-310: those are reasonable questions and have been debated before on Pprune. Isn't it amazing how little interest most people have in their own recent history?
Last night we landed on runway 12 at Wash. Dulles, about 2200 local. Although we knew nothing about this situation, it looked strange to taxi north on either Zulu or Yankee outer taxiway to later turn east at Bravo, as we passed what looked like a BA widebody on the inner taxiway or a ramp area. This was just east of the beginning or runway 01 Left. The plane had numerous airport shuttles (with those large "fins") parked right next to the fuselage. I call the shuttles landsharks, and they carry pax and crews from the main terminal to at least two other terminals, and vice versa-our gates are in 'B' terminal. Wish we had overheard something about it.
It looked like a strange, remote place to park, even for a chartered aircraft etc. Our nearby hotel has so many excellent tv channels that I never watched any news. This morning we taxied out to depart on runway 01 L at 0920 local time, making sure that all flows plus checklists were done and looking forward to seeing the sunny hills of VA and PA (via JERES on the Westminster 300* radial to JST, HAGUD, DJB...) and never noticed any other planes in the southwest area-and no BA.
