Stitching the Sky: Timelapse Jet trails 720p HD Version

This updated version features enhanced, up-converted original footage and new 1080p HD time lapse sequences, showcasing this feature the way it was meant to be seen. The original low res version: http://www.youtube.com/watch?v=Yqh_03-TFNUStitching the Sky is an artistic view of the marks left on our skies by high-flying jet aircraft. Sometimes annoying, sometimes spectacular, their presence also makes visible the motion of the upper atmosphere in ways that could not be fully appreciated without the magic of time-lapse photography. These scenes were selected from over 1000 sequences, captured in the skies over Santa Clarita, California from 2006 to 2008.The two UFO-shaped clouds at the end of the show are naturally occuring "Lenticular" formations. See the original footage and description here: http://www.youtube.com/watch?v=q5siFGdBZksThe soundtrack is "Stitching the Sky" from the "TimeShift CD, composed and performed by Technician (yours truly).

Jet trails clearly interact with existing weather conditions at different altitudes, and can evaporate quickly in dry air (called "Contrails") or linger for hours and days (called "Chemtrails") when deposited in atmospheric layers with higher humidity levels, as their particles (aerosols) provide man-made nuclei for combustion-produced, and pre-existing atmospheric water vapor to condense upon.Natural atmospheric conditions/air movements can be extremely dynamic, causing these artificial clouds to expand, grow, and twist into many shapes which often become unrecognisable as jet trails over time. Mutant jet trails can resemble natural clouds or may cover the entire sky in a soupy haze. Trails may be thick or thin, start and stop abruptly, evaporate quickly or expand/spread, or any combination thereof in the same sky, as aircraft travel through atmospheric areas/layers which can be very different within as little as 500 feet apart.Jet trails are known to contain water vapor (H2O), and smaller amounts of CO2, CO, NO, NO2 and other gases, unburned hydrocarbons, and particulates (aerosols) of carbon and soot. Additional compounds may be created by intake and combustion of contaminates already present in the atmosphere.Additionally, by-products of fuel contaminates/additives are also likely to be present in jet trails. Chemicals such as Diethylene Glycol Monomethyl Ether (an anti-icing agent), barium t-octylphenol sulfide (an anti-oxidizing agent), barium-based biocides, fuel stabilizers and other additivies are possible. Aluminum oxide from microbe/moisture-related corrosion of aluminum aircraft fuel tanks may also be present (all of which are speculated here).Commercial cloud seeding (silver iodide crystals, etc.) and government/scientific weather modification experiments are well documented, but such programs are likely to be small scale and not generally visible to the public on a daily basis as we see in our skies today.The intentional spraying of aerosols for geo-engineering, and toxins for subversive purposes have also been speculated and connot be ruled out, but the vast majority of world-wide trails we see are more likely the unintended by-products of large-scale corporate money-making activity, i.e. the huge number of high-altitude commercial flights each day, rather than global black-ops programs intended to intentionally harm the entire human race (which, incidentally, would also harm the conspirators, their families, friends, wildlife, etc.).In any case, jets trails are not harmless. Their man-made clouds have been shown to alter and pollute our atmosphere in many ways. The exact chemical content and atmospheric physics of jet trails are still evolving sciences, and much is being learned. There is a great deal of fact and speculation available online for us to study and contemplate. All who are interested are encouraged to further seek, study, and understand the problems and concerns associated with this man-made phenomenon...
