"Chemtrails - US Military Continues

Col. Walter Washbaugh, Chief of the Congressional Inquiry Division for the Secretary of the Air Force in Washington, DC, also calls chemtrails "a hoax". In an April 20, 2001, letter to a US senator, Washbaugh blamed the increased number of contrails on "significant civil aviation growth in the past decade".

He was right. A National Science Foundation study has found that, in certain heavy traffic corridors, artificial cloud cover has increased by as much as 20 per cent since the jet age took off. Dr Patrick Minnis, a CERES atmospheric researcher and ardent chemtrails critic at NASA's Langley Research Center, reports that cirrus cloud cover over the United States is up five per cent overall because particulates in engine exhaust are acting as cloud-forming nuclei. As the number of flights currently exceeds 15 million annually worldwide, the NSF, NASA and EPA predict artificial clouds will intensify as air travel continues climbing sharply.

What about chemtrails? Colonel Washbaugh ascribed widely reported grid patterns to overlapping aircraft flying north-south, east-west airways. The only thing wrong with this explanation, an air traffic controller told me in Texas, is that US airways do not run north-south.

The biggest laugh came when the colonel told the senator: "The Air Force is not conducting any weather modification and has no plans to do so in the future.

"Summary of Results

The goal of this research was to determine if there was a type of trail that was inconsistent with normal contrails, especially with regard to increased persistence. What was found is that highly persistent trails that last for many hours were seen above Houston, TX on a majority (60%) of observable days during the data collection period. However during this time period none of the 46 Flight Explorer confirmed contrails observed persisted for over 30 minutes and most contrails were under 30 seconds of persistence. Additionally it was discovered that the jets that were responsible for leaving highly persistent trails that last for hours did not ever appear on Flight Explorer and were documented for 8 separate instances, including one instance with two jets in formation. These unidentifiable jets were found to produce a contrail that was consistent with confirmed contrails during the periods when they weren't leaving highly persistent trails. Highly persistent trails are often seen in the form of isolated relatively short strips, as well as large areas of cirrus aviaticus clouds, but on rare occasions have been seen in totally unique grid and wheel formations.

It is hoped that others will endeavor to repeat these observations and publish their results. By repeating the basic observations for persistence length and whether the flight appears on Flight Explorer, it will be seen whether or not a trend emerges confirming the existence of a unique category of trail. Atmospheric differences due to higher moisture and colder temperatures in different locations will produce greater maximum persistence observed for identifiable traffic. For those in locations with greatest contrailing potential, the task of collecting data on highly persistent trails from unidentifiable flights will be hardest.

In this research I have gone to great lengths to measure and characterize my observations as accurately as possible in order to provide the clearest representation possible given the resources available.
