Hi booNy. Thanks for posting Bruce Macabbee's length estimates (and thanks again for all of the information you've been posting on this topic. You dug up a lot of great stuff!)
The lights I was playing with in Google Earth are flares 5 through 9 using Maccabee's numbering scheme. The pattern I laid out is about 2 miles long. That may be a bit longer than the distance Bruce would have estimated for that portion of the array, but it's pretty close and well within the margin of error considering the coarseness of the data we're working with.
I must defer such, however, if I'm to be honest with myself. A great deal of the information about the Phoenix Lights comes from much more deserving sources like Bruce Maccabee, Czero 101, lost_shaman, psyche, and yourself. My additions have been modest at best. Almost everything that I have brought to the table regarding the Phoenix Lights has been from others and I can take virtually no credit.
