They would have us at 1000, last time I was there, to be above landing traffic for 33 at DCA, and below the altitude from traffic crossing above on Route 6. Of course, each time, there actually was traffic crossing below us on short final to 33.
Big question is what/who did the helo crew see and call in sight?
