Q&A: Government is not spraying chemicals

Government is not spraying chemicals

I really hope you can help. A friend showed me in the sky long trails that follow some jet aircraft. I thought these were contrails. He contends that contrails disappear after a short time, while these trails remain across the sky. He contends these are chemicals that are being sprayed into the sky for unknown reasons by the government. What can you tell me about these mysterious trails?

Ah, the old "chemtrail conspiracy" theory.

The idea that the white lines of condensed water vapor that you see following planes, contrails, are really a toxic substance intentionally being sprayed on people by the government has been around at least since 1996.

That year, the Air Force received a study that looked into future weather modification possibilities as a method of maintaining U.S. military dominance. One of the elements of that paper discussed spraying toxic substances into the air. (Here's a link to that paper: www.fas.org/spp/military/docops/usaf/2025/v3c15/v3c15-1.htm.)

The Air Force said the study was a what-if scenario only, that it "does not reflect current military policy, practice, or capability" and that it is "not conducting any weather modification experiments or programs and has no plans to do so in the future."

It has received thousands of complaints over the years about "chemtrails," and denies they exist. It says the theory is a hoax that "has been investigated and refuted by many established and accredited universities, scientific organizations and major media publications."

One of the things most cited by conspiracy believers is the visibility of the trails for extended periods, which they say doesn't happen with contrails. The Air Force disagrees, saying contrails can be visible for several hours, depending on atmospheric conditions.

Here is a link from some critics of the conspiracy theory: www.skepdic.com/ chemtrails.html. And here's a link to a newspaper story: hamptonroads.com/node/227181.

For additional reading material on both sides of the subject, just type "chemtrail conspiracy" into a search engine and gorge yourself.

Driving the Blue Ridge Parkway

Are motor homes allowed on the Blue Ridge Parkway. If so, are there any limitations as to height and length?

Yes, motor homes are permitted on the Blue Ridge Parkway, which runs 469 miles from western North Carolina to northern Virginia. Commercial vehicles are prohibited without specific approval. The only limit on motor home size is what will fit through the 26 tunnels, mostly in North Carolina. Here are websites that may be useful in planning your trip:
