Orange/white ball of light seen bouncing like a ping pong ball north of Fairchild Airforce Base Washington

December 8th , 2012.  My wife and I live about 1.5 miles north of Fairchild Air Force Base in Washington state.  On Saturday night Dec 8th 2012  at approx. 11.45 PM L  I was out on my sun deck and to the north west, above the tree line,  I saw an orange orb.  It was way up in the sky and I kept on watching it  thinking it was just a  star.  
Suddenly it started to change colors from orange to red to bright white.  As it was changing colors, it continuously got larger and larger.  Then it turned to bright white, it suddenly streaked down toward the ground and just before hitting the tops of the tree line it stopped and changed back to orange in color.
The orb just stayed there in position for several minutes.  Suddenly it started to change colors again from orange, to red to white all the while getting larger and larger.  When it changed to bright white, it went straight up in to the air and stopped at a very high elevation above the tree line and went back to orange in color.
After a few minutes of just sitting there, it  started to change colors again from orange to red to white. When it changed to white, too suddenly streaked down towards the earth at about a 45 degree angle. It appeared to have bounced off the earth surface and right back up in the air at an apposing 45 degrees and then faded away into the darkness. no sound ever was herd, either.
This went on for about one half an hour.  I have four other witnesses that saw this happen.
