From my office I can see planes taking off to the west from BKL. I saw one of these 757s depart Burke during the NBA playoffs. It was during the day, so assuming it was Cavs going to NYC? I also saw a sub-hunter 737 variant take off from there during the Titan submarine search.
I think the terminal building there has public access. There is a women’s aerospace museum in it I keep meaning to check out.
