Dear Clifford,

Below is Sen. Feinstein’s cover letter and the attached letter to her
from Col. Walter M. Washabaugh.

May 16, 2001

Dear Mr. Moors

With reference to your inquiry concerning “chemtrails”, I have received
a response from the Department of the Air Force which I am enclosing.

I hope that the response is helpful, and that the information it
contains will clarify the situation for you. If you have further
questions, or if my office can assist you with any other federal
matters, please do not hesitate to call on me again.

Once again, thank you for contacting me.

With warmest personal regards.


Dianne Feinstein

Dear Senator Feinstein,

This responds to your inquiry for Mr. Rick Moors concerning

The term “chemtrail” is a hoax that began circulating approximately
three years ago which asserts the government is involved in a joint
federal program of covert spraying of the public. The “chemtrails” are
most often described as “unusual contrail or contrail patterns” seen
coming from military and civilian aircraft. The “chemtrail” hoax has
been investigated and refuted by many established and accredited
universities, scientific organizations and major media publications

There has been an increase in the number of contrails observed due to
the significant civil aviation growth in the past decade, and the
patterns observed are directly correlated to the grid pattern formed by
aircraft flying north/south and east/west routes designated by the
Federal Aviation Administration (FAA). The FAA manages the National
Airspace System (NAS) and controls both civilian and military aircraft
using the NAS. The National Aeronautics and Space Administration (NASA)
and the National Oceanic and Atmospheric Administration (NOAA) are the
agencies charged with conducting atmospheric and climate experiments and
are investigating the effects of contrail formation and dissipation on
the climate.

Aircraft and their engines can produce a variety of condensation
patterns (“contrails”), exhaust plumes, and vapor trails. Furthermore,
the Air Force performs missions during which, exhaust is released into
the atmosphere. The exhaust emissions produced by aircraft and space
launch vehicles can produce contrails that look very similar to clouds
whcih can last for only a few seconds or as long as several hours.
Vapor trails are formed only under certain atmospheric conditions and
create a visible atmospheric wake similar to a boat propeller in water
and usually dissipate very rapidly.

Contrails consist ofice particles that form or nucleate around the small
soot or aerosol particles in the exhaust hases. The contrails are
formed when the relative humidity increases because of the mixing of
warm and moist exhaust gas with colder and less humid ambient air of the
atmosphere. Contrails become visible roughly about a wingspan distance
behind the aircraft. Contrails can be formed by propeller or jet
turbine powered aircraft.

The contrails formed by the exhaust at high altitude are typically
whicte and very similar to cirrus clouds. As the exhaust gases expand
and mix with the atmosphere, the contrails diffuses and spreads. At
sunsets, these contrails can be visibly eye-catching and striking as
they reflect the blue, yellow and red spectrum of the reflected
sunlight. Due to horizontal wind shear and a (comment – sentence ends

A different type of contrail or condensation trail is caused when a wing
surface or winglet causes a cavitation of iar in very humid conditions.
This results in a unique vapor trail that is not formed due to exhaust

Aerial spraying for pest or weed control and fire suppression is the
only Air Force activities that involve aircraft intentionally spraying
chemical compounds (insecticides, herbicides, fire retardants, oil
dispersants). The only unit in the Air Force capable of aerial spray
operations to control disease-carrying pests and insects is the Air
Force Reserve Command’s (AFRC) 910th Airlift Wing, Youngstown – Warren
Air Reserve Station, Ohio. The aerial spray mission uses four specially
configured C-130 Hercules turboprop iarcraft. Aerial spraying enables
large parcels of land or water to be treated safely, quickly,
accurately, and cheaply. This is the only fixed wing aerial-spray
capability in the Department of Defense. Although the Department of
Defense initiates most of the unit’s missions, its services are also
requested by local, state, and other federal agencies and coordinated
with the Center for Disease Control. The most common missions flown are
for mosquito, sand flea and weed control. Several states have also
requested support to combat grasshoppers and locusts.

For a number of years commercial companies have been involved in cloud
seeding and fire supression measures. Cloud seeding requires the
release of chemicals in the atmosphere in an effort to have water
crystals attach themselves and become heavy enough to produce rain. The
Air Force does not have a cloud seeding capability. The Air Force’s
policy is to observe and forecast the weather to suport military
operations. The Air Force is not conducting any weather modification
experiments or programs and has no plans to do so in the future.

In short, there is no such thing as a “chemtrail” -the actual contrails
are safe and are a natural phenomenon. They pose no health hazard of any
kind. We thank you for this opportunity to address your concerns and
trust you find this information helpful.
