Same, I live in San Diego where there are lots of military helicopters and activity in close proximity to SAN. I mostly see them go directly above the airport. I wonder what is different about DCA (maybe noise abatement?) why this isn't done.

DC has a staggering density of restricted airspace; Reagan National has unusually tight approach/departure requirements... so it doesn't surprise me that if this was going to happen somewhere, it would be there.
