Michael J. Murphy, in his film What in the World Are They Spraying, claims that "normal" contrails are always short and dissipate quickly, and that's how you can tell the difference between contrails and chemtrails. But science and history tell us that contrails can persist and spread for hours.
In this clip from a Q&A session at San Diegans for 9/11 truth, Michael Murphy is asked abut this distinction.
He now admits that persistent contrails exist.
So how can you tell the difference between a contrail and a chemtrail (which is what the questioner wanted to know, so she could explain it to people)? According to MJM, you can't tell the difference unless you chemically analyze it.
At 1:25, MJM:He then goes on to say that the conditions for persistent contrails are "rare" (but does not define how rare). But the point is made. He can't tell what is a chemtrail, and what is a persistent contrail. He just think's there's more persistent contrails than there should be."Persistent contrails are just natural contrails, they do not contain the high amounts of aluminum, barium, strontium, and other fall-out that matches geoengineering and numerous patents exactly. So with that being said, a persistent contrail is a contrail that lasts a little bit longer, and they have been seen as far back as World War Two."
So, Michael J. Murphy, will you now issue a correction to your claims that you can tell the VISUAL difference between a contrail and a "chemtrail"? Or at least issue a clarification?
What IS the difference between a contrail and a chemtrail?
