Awesome work putting JFK on the map! I notice you were using only Bing Maps aerials when drawing.

I have a custom 1996 NYC imagery source that could help making these old building footprints more accurate:

Note, you can swap out the "1996" with 1924, 1951, 2001-2, 2004, 2006, 2008, (all even number years afterward) to access other aerials.

I understand you primarily map in FL, but these map tiles will certainly make historic mapping in NYC a breeze!
