Since the error message is within a debug statement, it seems
appropriate to repeat the words of advice an old pilot friend of mine
once gave on making emergency landings at night in small aircraft:

"First, turn off your strobes and landing lights - you want to be able
to see well outside the aircraft.  Find a road.  Fly a normal
left-hand pattern, and as you turn base to final, turn your landing
lights back on.  If you don't like what you see, turn them back off
