Former aircrew (communications), i have been observing since 1994, flight paths, maneuvers, various altitudes, brightness, etc., and now i am trying to communicate with them. this area is big with celebrations, new years, 4th of july, etc. and for the last 3 celebrations i have seen a pattern (i am not the only witness, but will or has anyone come forward, ??). i think they are attracted to the frequency of the bottle rockets, or within the harmonics of the whistle during launch. 2015 july 4th, 2016 new years, and 2016 july 4th, multiple craft appeared observing the celebrations, others in town in various locations had to witness, they were that obvious. the main color of lights they display is red, but it also looks orange, yellow, white all mixed together. over the last couple of months i have confirmed, in my belief, i have communicated with craft with flashing light from me, led works best, sending prime numbers, maximum, 1-13, and about 90% of the time, acknowledgement from the craft, with a single flash/pulse of light has been observed.
