Possible Crashed UFO In Oregon's Maury Mountains In The Summer Of 1967.

During the Summer of 1967 my parents and myself went on a camping trip in the Maury Mountains of Central Oregon.  The campsite was around 30-35 miles east of Prineville, Oregon past a small village called Post.  
One night during the trip I was awakened by a streaking lime green fireball moving very quickly across the sky.  It was emitting sparks (also lime green in color) and I could hear a crackling sound from above.  This whole memory is only remembered in a dream-like state.  
In the brush across from the campsite about 30 yards away I saw a creature in a spacesuit-like outfit.  It was short and rotund, like the Michelin Tire Man.  It was in a form-fitting light brown color jumpsuit/spacesuit outfit.  It also wore a dark brown space-helmet with some sort of night vision/binocular type device in front of where it's eyes would be.  It stood about 4' tall.  It was just observing our observations of the fireball streak.  
However the next morning a group of military personnel in a jeep and two US Army trucks questioned my parents about the event.  I think they were working on the idea that this was a crashed UFO!  
I remember the creature probing my emotional state at the time.  Were we being tested in some way?  My parents are no longer around, I'm 47 years old now, and I was 9 years old at the time.
Date of incident may be approximate, although the witness does not indicate that fact.  PD
