Welcome fellow astronomer! I have seen every type of contrail there is, I’ve flown in damned near every type of passenger plane there is and have seen stuff that, to an uneducated mind looks like something suspect.
But, there is no reasoning with conspiracy theorists, they create conspiracies out of nothing, then have the audacity to ask the normal people to prove THEM wrong, rather than prove themselves right. And when you DO prove them wrong, they accuse you of being in on the conspiracy, then create a new one. Conspiracy theorists are the most lazy people in the world, they never, ever do the research to prove their point, they just create theories and ask the reasonable people to disprove them.....
Concerning the role of reason in confirming truth Aristotle and Plato, like many philosophers throughout history, wrote:
"People use logic, deduction, and induction, to reach conclusions they think are true. Conclusions reached in this way are considered more certain than sense perceptions on their own. On the other hand, if such reasoned conclusions are only built originally upon a foundation of sense perceptions, then, the argument being considered goes, our most logical conclusions can never be said to be certain because they are built upon the very same fallible perceptions they seek to better." Properties of logical systems consist of:
Quite frankly I disbelieve that the missile theory can be complete on a fundamental level. All arguments made in its defense have been speculative, intuitive and axiomatic assertation. At best a strong inductive form of the arguement may be plausible, however I outright disbelieve the possibility of it being cogent. The foregoing especially since the images at posts #51 & #303 are mutually exclusive with the arguments made in support of the theory. I believe this to be evidence for lack of consistancy. Therefor, the validity of the missile theory is entirely immaterial (if not outright irrelevent), and ultimately its soundness wholly moot.
