Observed 3 objects flying in a tri-angular (or V) shaped pattern... I pulled my car over and got out of car to watch them pass...appeared at first to be hot-air balloons...but as it was 10:30 PM, thought that to be unlikely...nearly passed directly over me...passed from due west to due east...had very bright light on front and alternating red/white lights on rear...seemed to be travelling at about 100-200 ft, at about 50 or so kts...hard to tell..didn't have anything to guage their size with...watched objects for 45 minutes...no sound heard...after losing sight of objects, I contacted my dispatcher who I asked to "Step out of the office, turn to the north, and look up"...which he did just as they passed over...afterward went to payphone to call 911 and tell officials about objects and direction of travel...member of ham radio skywarn group...also contacted media (an all news radio station WWJ, and local TV station ...while both were cordial, when I asked 911 operator if anyone else had contacted them, I was told that they couln't tell me at that time...but did talk to Mich State Trooper who told me, while being too far away to see himself, others were observing and following ...(I wondered what they would do if they were to catch them???)... Nothing appeared locally in the media...did see newspapers from Flint and Grand Rapids the following day have story on front pages...also, was told by two Huron Valley Ambulance attandents they had also seen the ojects... So what do I think they were?...Who knows...I just know what I saw ... I try to carry a palm corder around with me, and a scanner with a tape recorder...just in case...
