How Contrails Form
• http://www.boldmethod.comContrails are real - they're not a government conspiracy to spray chemicals (big surprise, huh?!?). But, did you know there are two types of contrails? Aircraft can generate both aerodynamic contrails and exhaust contrails.
There are 'contrails' but, contrails do not linger in the air for hours and hours spreading across the sky in order to create a gray haze by late afternoon...those are chemtrails. Funny how these contrails you speak of did not really exist the time we were growing up.
