FSX/P3D. Product Description: Enter Boston`s buzzing airspace with a wide choice of aviation options. New England`s largest city has plenty of helipads within its boundaries, some nice rural general aviation airports surrounding it and last but not least: Boston Logan. US Cities X is a series of city scenery for FSX that covers US cities created by LimeSim. Based on an extensive aerial image it will have all the major buildings and landmarks plus all the airports and heliports that are inside the covered areas. It is clearly intended to fill the gap between the default scenery and very high dense city scenery such as Manhattan X. Because the file size is rather large due to the ground image it only includes one season (in most cases this is not a real issue) and no night textures. The VFR flights over these cities are mostly a day time affair anyway.
