As the chemtrail conspiracy theory spread, federal officials were flooded with angry calls and letters.

Various versions of the chemtrail conspiracy theory have circulated through Internet websites and radio programs.

Alleged secret experiments with aircraft exhaust modification are one version of the Chemtrail conspiracy theory.

The song's title refers to the chemtrail conspiracy theory, as do the lyrics: "I can't believe/What we've seen outside/You and me/Watching the jets go by".

The chemtrail conspiracy theory posits that some trails left by aircraft are chemical or biological agents deliberately sprayed at high altitudes for purposes undisclosed to the general public in clandestine programs directed by various government officials.

In 1996, a chemtrail conspiracy theory began to circulate when the United States Air Force (USAF) was accused of "spraying the US population with mysterious substances" from aircraft "generating unusual contrail patterns."

Proponents of the chemtrail conspiracy theory say that chemtrails can be distinguished from contrails by their long duration, asserting that the chemtrails are those trails left by aircraft that persist for as much as a half day or transform into cirrus-like clouds.
