The drawing in this link, some think is a stadium, but could it also be the Capitol?

Now, looking at it as the Yankee Stadium that was posted (Longer in dimension from east to west),(I don't know how the stadium sits geographically. I'd say those ends we see in the drawing were the ramps and the curved portion would be one edge of the stadium....visual landmarks. The direction of plane travel would basically slice the stadium into two stadium isoceles triangles. Putting all dates, times, recent events together...I'd say it was the stadium but I'm being greatly influenced by the OU dude bombing. You simply can't discount it. I think the OU dude had the wrong date (10-01 instead of 10-11).
