2004-03-20 - Mesa, AZ - Changing

I saw for a 2nd time a cigar or oval object that seems to flip and bobel as it's flying changing form from oval to doubled winged shap

This is my 2nd time reporting and each time I have seen the same object, but on my last report I left out a couple details than the one im reporting now. My last report was on 1/17/04, but i have seen this object on a total of 3 times. well on 3/20/04 between 6:30pm and 6:45pm my son, who also witnessed this sighting twice, ran into the apartment and said "the same object is outside again dad", I ran outside this time my wife was a witness and to my suprise there it was, it was travling from west to east coming from phoenix and tempe to mesa between 8th ave and extention where I live. It was travling at a speed and altitude that a helecopter would travel, the object is about the size of a helecopter but it's not a helecopter. The object is black and when it's moving iit seems to be bobbling or flippin continusly, it makes no sound at all. The first time i seen the object on 1/17/2004 it was moving very slow but on 3/20/04 it was moving fast and coming straight for us, I was waiting for it to past over us to see under it and to see it closer but it suddenly stopped and began to travel upward into orbit but at a slow speed as it did last time on 1/17/2004.The object seems to change shapes from a cigar or oval shape and as it's flipping appears to change into a doubled winged shape object. about 10 minutes after seeing this my son reported while ridding his bike he saw another one, this one was black on one side and red on the other side when it flipped over. I'm very upset because i had to pawn my video camera back in december 2003. I'm 33 years old and work partime at Skyharbor airport, I often see military aircraft taking off from the national gaurd next to the airport but I have never seen anything like what I have been seeing. Also shortly after the object leaves, on each occassion, a helecopter shows up and seems to circle the area..
