(1) We have been seeing contrails since World War II. You can find videos of bomber formations heading to Germany, issuing profuse contrails. I think the escort fighters were also doing this.

(2) Civilian airliner traffic began the changeover to jet aircraft around 1960. They operated up to the tropopause and often produced contrails.

(3) With the introduction of new wide-body aircraft and high-bypass-ratio turbofans, civilian airliners began to operate at higher altitudes (e.g., 40,000 feet) where conditions for contrails are more favorable (dry and cold). That was 15-20 years ago.

Nations are like herds of sheep. They will gather together over what sounds good, whether or not there is any actual problem. Witness what is going on with "climate change" (the former "global warming").

I am not blind to anything. I see contrails daily, being at the south end of a major international airport. I have seen lenticular clouds and understand how they form. I have seen condensation form from overwing airflow (same process). I have studied aircraft wakes as part of a research program to detect them at a distance.

Wiggington is not even remotely close to being correct in his key assertions. Would you pick a brain surgeon for your daughter based on "it doesn't make him completely wrong in everything." You are replacing scientific substance with a crap game. "Oh, he's a rotten shot, but sometimes he hits the target." You are in no position to know whether he hits the target at all, and neither is he.

All you have left is your ignorance ("something is not right") and wishful thinking ("only a fool would deny that"). Well, you are in a rather poor position to be calling an expert in the field a fool, when all you have are questions and I have the answers.
