A high-flying jet leaving a condensation trail (contrail) According to the chemtrail conspiracy theory, some trails left in the sky by high-flying aircraft are chemical or biological agents deliberately sprayed for sinister purposes undisclosed to the general public.[1] Believers in the theory argue that airplanes don't leave long-lasting contrails under normal conditions,[2] but their arguments have been dismissed by the scientific community: such trails are simply normal water-based contrails (condensation trails) which are routinely left by high-flying aircraft under certain atmospheric conditions.[3] Although proponents have attempted to prove that the claimed chemical spraying does take place, their analyses have been flawed or based on misconception.[4][5] Overview.
