While investigating a mufon sat case from march 19,2017 over mesquite nevada, a witness contacted sat investigator bob spearing (#9921140) to relay his story of a may 25th, 2017 close encounter with spheres and a black triangle over mesquite, nevada. mr. spearing asked the witness many questions as follows but nevada mufon may want to follow up with this very credible witness who is a 82 y/o retired city inspector for mesquite. he doesn't require anonymity. his story: "on may 25, 2017 at exactly 10;30 pm in my backyard in mesquite proper, my wife and i observed a group of 4 or 5 dark sphere-like objects, small, but it was hard to judge in the dark. they gave off the faintest "tan light". there were either 4 or 5 of these objects doing circular and figure 8 patterns over my house at low altitude or they were coming in waves and there were many more that 4 or 5. this continued for 30 minutes till 11 pm. they made no sound and had no navigation green and red lights and no-anti-collision strobes. " "then they departed. almost immediately after, we noticed a huge dark shape silently approaching the house at under 500 feet in altitude. it took 3 minutes to traverse the sky from southwest to northeast. it was bigger than a 747 and was jet black. it had no lights on its bottom but it gave off the faintest blue glow underneath. it was a triangle. however, the rear of the triangle was not a straight line. it seemed to indent a bit coming in from both points and then go straight again point to point. (this may have been wing tips-bob s.)." (witness stated the apparent size of the craft was bigger than my hand outstretch which means the object covered at least 10 degrees of sky at 500 feet in altitude making an actual size calculation possible.- bob s.) "i was too dumbfounded to get my camera." (witness has agreed to draw and submit the shape of the craft but has not done so to date. -bob s.) feel free to contact bob spearing (mufon #9921140) if necessary.
