Whoever told you that is either a paid debunker or is just talking off the top of their head.

Contrails are very rare. I grew up within 30 miles of one of the busiest airports in the world (Tampa Bay International) and I was lucky to see 2 or 3 contrails in a year. They are very rare.

The old pics and videos of contrails that look like chemtrails I believe are very well-done fakes. I've watched old jet and plane videos for decades and have never seen one that contains contrails. Never.

These are just very convincing lies to convince the ever-so-willing-to-believe public that what they see right over their heads is not really happening.

Denial is a powerful thing.

Thanks for your kind comments.
