Group to see the "un-explained"in the night sky.

The group that I was with had set out on a " mid-night" hike.The approximate length of this hike was one and one-halve miles.The location and the terraine as well as I can remember was slightly hilly and no hills were over 300 ft in height from a standing on ground prespective,with trees."Waves" of warm and cool air also were recognized.I have not mentioned this episode in my life,with the exception of a few trusted close friends.The object appeared to have had rotating lights and no sound.the lights were of different colors than those on any air-craft,which uses red,green and clear-"white" lights.I cannot determine what type of "vehicle" or "craft" this had been.Upon seeing it with others we were not apprehensive or otherwise but aware of the situation at hand.I wish you at NUFORC the best and that the "endeavor" of your work will hope-fully be realized.
Date of incident in June 1973 is approximate.  PD
