Approach Control had vectored me onto what seemed like a wide downwind leg to Washington Dulles International. My problem was he still had me at 5,000 feet. When I was abeam the numbers, waiting for an answer to the mystery, he turned me over to the tower controller who said, "cleared to land." I replied, "That's a long way down;" to which he responded, "Roger." Since I wasn't flying a Stuka dive bomber at the time, it took gear extension, full flaps and an extra long downwind leg to get me down in the same time zone as the airport.
