Bri,
You have just cornered the 'What Airfield' and 'What Cockpit' threads!
You are indeed correct. It is Nielsen Field which was the HQ for the US Far East Air Force at the start of WW2.
Sadly, Nielsen was taken by the Japanese to Japan and was never heard of again.
The tower/terminal now houses the Philippinas Hertigage Library.
The airfield was returned to the Ayala family after WW2 and was developed to become the area of Makati, the major business district in Manila. The runway became one of the roads running through the area but, thankfully, the tower still remains albeit dwarfed by some of the building surrounding it.
