As Gary indicated, aircraft flying up the east side of Manhattan in
the VFR corridor are required to turn around and fly back to the south,
as the corridor ends around the north end of Roosevelt Island.

How does an aircraft hit the north face of a building along the river
there? One possibility is that the pilot lost control of the aircraft
during the turn, say due to a stall. Another possibility is that the
pilot
misjudged the point at which to begin the turn.

My guess is that they flew too fast and failed to remember that the turn
radius increases with the square of the airspeed. When they saw the
buildings coming, they banked steeply, causing them to descend and possibly
stall. (A witness on the ground who is also a pilot reported seeing the
plane in an unusually steep bank just before impact.)
