Eight dim red rectangles in a string traveled slowly then went out one by one, appearing to dissolve.My friend and I, both men, were traveling westbound on 300 E 7000 S in Salt Lake City, Utah, at 9:15 pm on Wednesday, November 14 2012. I first noticed the string of approximately 8 rectangular objects in a line traveling northbound towards the Salt Lake City Airport just faster than a plane would have traveled on approach, which still appeared slow. Together they formed a line approximately 2 - 3 times the length of an airplane in the sky, and as thick as two airplanes stacked on top of each other. They appeared to be a little bit higher in the sky than the approaching planes. The objects were very close to each other, but had a distinctly dividing black line between each light. Each rectangular object shined dimly in red light. I alerted my friend and asked "What is that?". He noticed it and we both watched it travel from south to north for about 10 - 15 seconds. Then, the first in the line went out followed closely by the second then the third a! ll the way back to the end of the line. The manner in which they turned off made the string appear to dissolve away.
