Sue, if you would, drop me an E-mail at email@example.com. I do not know much about the WWII time frame in Panama, butafter my retirement from the military in 1989 I worked for 7 years on Ancon hill for AT&T. I have a few photos of the area... very few actually... how many times do you think of taking your camera to work and taking photos of the work area?
Ancon would be a better than excellent area for anti-aircraft operations. The hill has a very good view of Panama City itself and of the Pacific Ocean. About three miles on the other side of the Pan Canal is/was Howard Air Force Base which would have been a major target for enemy air activity (not to mention the canal itself).
