Question: Which one is a real ICBM? Answer: None of them. They are all contrails. (Trust your eyes)

Good post. Aircraft contrails are not unified, there is a separate contrail for each engine so you see a combination of parallel contrails forming a flattened ribbon contrail.

Not so on this contrail, it is clearly from a single propulsion unit.

Also, this contrail is significantly more dense and opaque like the exhaust from a solid propellant rocket; pure water vapor contrails from a jet engine are more transparent and breakup at distance.

This object is moving very fast, there isn't enough lag time for the change in trajectory of the contrail to be explained by cross winds. However, a gimbled rocket motor makes exactly those kinds of trajectory corrections, particularly during the boost phase.

Also, planes fly parallel to the earth surface. If so, the object should be getting larger as the object approaches. But its not, its getting smaller because it's going up, not flying level.

Finally, I post on a pilot's blogsite and the dozen or so posters universally agree that it is not an aircraft contrail, too dense.
