Washington National Airport (which had Ronald Reagan pre-pended nearly 50 years after coming into service) was full-blown runway-wise the day it opened in 1941.
It has lost the short east-west runway since then. That runway was too short for large planes and planes skimmed over St Elizabeth's (mental) Hospital on the hill across the Potomac.
Work is underway for a new, consolidated headquarters campus for the Department of Homeland Security. The new DHS headquarters will be located on the site of the old Saint Elizabeth's Hospital in Southeast Washington.
No comments please about DHS moving to the former mental hospital site.
