um what about the fact that contrails only work at certain altitudes and yet I've seen several of them at different altitudes creating the "contrails" ?
They appear under the right atmospheric conditions, which are dictated partially -- but not completely -- by altitude. Pressure and temperature are the key factors.
...actually a while back there was a report from a mechanical engineer saying he saw strange goings on while repairing a jet...
I also once heard a vague third-hand story of a guy who saw something strange. Does that mean any crackpot idea I come up with should be taken seriously?
...its quite old but its from the inside man!!
I am an engineer. "Chemtrails" are bogus. They're easily explained, easily understood condensation trails that occur as a natural consequence of operating jet engines under various conditions.
anyway riddle me this, usually the contrails dissipate within minutes of the aircrafts passing yet these ones not only do not dissipate but spread.
Atmospheric conditions. Contrails will either dissipate or not depending on them. Atmospheric pressure and temperature vary with altitude, time, and weather zones.
