The simulation starts out with the asteroid 50 km south of the impact point, at an altitude of 14 km above the surface of the water. The land is granite. Water and atmosphere are included. Of course, the exterior of the asteroid is never 'cold' in this simulation, so we always see asteroid material as orange. The viewpoint is from orbital altitude at a location about 100 km west of New York City, looking east.
Long Island trails off into the distance.
Manhattan and Staten Islands are in the foreground and Long Island Sound and the Connecticut shoreline are to the left. Just before the asteroid strikes the water. Here is a 53K gif file of this image. 0.66 seconds after impact. Here is a 71K gif file of this image.
