Beyond...
And What If These Contrail Objects Are Beyond Our Current Technology?
If these objects are not made by human hands -- which is a possibility -- we will have to look much further and deeper into the activities of these "mystery objects" and consider their potential function in our atmosphere. Based upon observations and information gathered from photographs and videos, they seen to be performing a variety of functions which suggest weather control, atmos-forming and cloaking of larger objects.
Perhaps these objects (for lack of a more definitive description) have always been here as an undiscovered part of our planet and are now using contrails as a novel form of transportation?
Research has just begun in attempting to identify and track not only specific types of persistent contrails and unusual contrail patterns, but to gather data from observations, high altitude photos/videos and satellite images of these particular object's activity. It is believed that with diligence, these objects could be systematically observed visually and digitally and tracked by independent researchers.
If what we are attempting to research is not human made technology... then we are dealing with a unexplained terrestrial environmental event/entity/species, an extraterrestrial entity or object or an "event" that has yet to be discovered or revealed by current science. Obviously, this presents multiple problems for those attempting to observe and gather physical or photographic evidence. (see MUFON Director John Scheussler's "Detection & Identification Of UFOs Using Existing Technology" at http://www.sightings.com/ufo6/idufos.htm)
Yet if researchers are attempting to uncover a physical entity or ethereal form beyond current technology or scientific understanding – is this research expected to conform to current scientific method, tests and measurements which likely are incapable of measuring superior and advanced technology or lifeforms?
It certainly appears that UFO researchers are called to incorporate the designs of social science, apply the most appropriate scientific methodology while expanding the intuitive and interactive aspects of understanding. Perhaps a new science which includes astro, exo and crypto biological, social, behavioral and interactive components in addition to technological knowledge is in order.
Contact with either undiscovered life forms indigenous to this planet or extraterrestrial life is not only profound in the realm of scientific discovery – it is a profound human awakening to and interaction with the unknown. Because of the very nature of this type of research -- researchers from a variety of perspectives looking at the persistent contrail phenomena -- may be required to move beyond the constraints of human systems and scientific approaches forging new pathways of understanding this phenomena... if its origin remain unexplained by human research and development.
