Lateral thinking and had already been studied at Embrey-Riddle( goes to show, there is no such thing as an original idea) Using passive reflector panels to mark an unlit runway. Regardless of legality...if you are going to do something stupid, at least, give yourself a fighting chance. ER's study showed the panels were visible from 5nm away, allowing maneuvering to land, lit only by landing lights. My personal addition would be to survey in something like an aircraft carrier meatball like glideslope indicator to give some amount of obstacle clearance. When I mean survey, I mean simple measurements, erect panels at measured heights a measured distance apart aligned with the strip.
Stupid it may be, but if it saves one life....
