you just stare at Passur for a little while you'll see planes all over
the place dropping from the display where there are no airports.

Aircraft appear and disappear in Passur presumably due the sporadic radar
returns caused by the low altitudes flown by aircraft in those VFR
corridors combined with the tall buildings of the area.

So assuming the up-the-East-River account is correct, how did Lidle (or
the instructor) manage to hit the north face of the building? That
seems an impossibly tight turn.

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.
