Mary, I'm over 50 and we've had contrails as long as I remember. There are photographs from the WW2 that shows the sky full off contrails. We see more of them now because there's more air traffic. And it's completely wrong to say contrails disappear rapidly. You're just parroting things you've read previously without doing any of your "own research" that conspiracy theorists keep bleating on about.
