PhysicsTeacher has been quite an active scenery developer, generously sharing his work for free, especially in the New York area.
A couple of his friends noticed that this (quite big) heliport was not in the sim. Heresy, right? PhysicsTeacher thought as much, and he got his hands dirty.
HHI Heliport features 2 large hangars, ground facilities, quite a few parking spots, and, like I mentioned above, is very close to Manhattan.
In the general vicinity of the heliport, you can find the Lincoln Highway and the Pulaski Skyway got some love as well. Both are part of the package, on separate folders so you have the option to go with the default scenery or the new ones.
