Average contrail duration for all observed commercial jets lasted approximately 15- seconds. But the
average for all military flights recorded at comparable altitudes in the same airspace and timeframe was
6.25 hours.
This was an enormous difference! The persistent plumes left by these military aircraft were lasting
1,500-times longer than their commercial counterparts. The persistent plumes always emanated from
KC-135 and the KC-10 aerial refueling tankers.
Commercial aircraft tallied in the Houston study included the Boeing 752, Boeing 757, Airbus, DC87,
Boeing 733, Learjet and MD80 flown by Southwest, Air Canada, Northwest, American, AeroMexico and
Federal Express.
While Flight Explorer does not provide altitudes for unidentified military aircraft, the FAA states that
“heavy” military aircraft usually transit U.S. commercial airspace around 30,000 feet to ensure safe
separation from airliners flying at 35,000 to 39,000 feet.
The Air Force confirms that its tankers do not fly at contrail forming altitudes in order to reduce hook-up
times for fuel hungry fighters.
With air temperatures dropping 3° every 3,000 feet, the higher-flying airliners should have been leaving
longer-duration contrails. Steadham’s study found just the opposite!
Basic atmospheric physics states that the lower-flying tankers could not have been leaving such longlingering
plumes – unless they were spreading fine particulates in their wake.
CLOUD RECIPE
Vincent Schaefer is a Naval postgraduate who invented iodine cloud-seeding techniques first widely
used in 1946. Joseph Moran wrote the classic textbook, Meteorology. Both experts agree that clouds
form when water vapor accretes around particles of grit acting as attracting nuclei.
And NOAA’s and NASA’s atmospheric studies – including TARFOX, ACE-Asia, ACE-I and II, INDOEX
and Project SUCCESS – have since confirmed that the only way to form artificial clouds under
conditions of low humidity and less than ideal temperatures is by dispensing additional particles from
aircraft.
In other words, when atmospheric conditions prevent the moisture-attracting nuclei left by aircraft engine
exhausts from forming contrails, chemicals added to the fuel can leave enough extra particles
exhausted to create artificial clouds when the relative humidity is less than 70%.
Modeled by Paul Demott at Colorado State University’s Department of Atmospheric Science, the
principle factors determining cirrus cloud development are temperature, relative humidity, and aerosol
size. The last variable is of primary importance, and may be supplied either inadvertently or deliberately
by high-flying aircraft.
MAKING CLOUDS AND RAIN
At the National Center for Atmospheric Research (NCAR) in Boulder, Colorado, Al Cooper also studies
the tiny particles that form the nuclei of condensing clouds and raindrops. Cooper says that burning
tropical forests and grasslands may be the largest source of these cloud-forming particles. Other cloud
condensation nuclei come from airborne dust, sea salt, the nitrogen and sulfur compounds released by
aircraft engines, as well as very fine particulates released by specially equipped aircraft. Spread a few
extra nuclei like silver iodide into highly humid air and rainfall results.
