Of all the conspiracy theories, this might be the one I hate the most (aside from flat earth theory, which is just absurd).
CONTRAILS are a normal, understandable, and even forecast-able phenomena. When the upper atmosphere has the right moisture and temperature, the bergeron process is initiated creating long lasting contrails. The Military actively learned how to predict and forecast the formation of contrails as they could seriously jeopardize covert military operations. A sounding from Buffalo this morning shows quite an abundance of moisture aloft that was just waiting for the perfect trigger to condense and form ice crystals. I didnt dig too deep into the appleman charts, but it appears that the upper atmosphere was near ideal conditions both temp and humidity wise to make long lasting contrails.
