You're still ignoring this part: "I do not know how long it was there before my attention was called to it."
No, I'm not ignoring it at all. But how long it was their before he noticed it is quite irrelevant. We're dealing here with what he saw
after his attention was called to it.
If the aircraft had already made it's turn, the smoke trail wouldn't appear to be moving, and at that distance and time it could have seemed to have been quite well defined.
And if it were a jet plane as you think, it would be heading directly away from him at a speed of as much as 500mph. Even if it was only 16 miles away from him to begin with, within 3 minutes it would be at least 27 miles away (if it was only traveling at the same speed as the Lockheed) and 41 miles away if it was at full speed.
At the same time a Lockheed was turning West and noticing the object on their right, because they were South of it. They would surely see this trail of smoke because they were looking the object's flight path from a greater angle than Johnson. Or was the magic smoke only visible from the back?
Although he says he "ran outside" we don't know for sure exactly how long his eyes were off it while he reached for the binoculars his wife had gotten for him, went to the door, perhaps put his shoes on,
Perhaps stopped for a cup of tea and buttered scone, stumbled into the hallway closet to get his hat and scarf... "perhaps"... however, he doesn't say any of that so we have to assume he ran straight outside (because he didn't want to take his eyes off it for any longer than necessary).
Stop making stuff up and covering your theory in "ifs" "perhaps" and "probablies"
opened the door, got in position, and then got the object focused in the binoculars. Consider this statement:
- I ran outside and started to focus the glasses on the object, which was now moving fast on a heading between 240° and 260°. When I got the glasses focused on the object, it was already moving behind the first layer of haze.
Yes, I wonder how he could see it at all to know it was moving fast, whilst it was at least 27 miles away... It's a wonder he managed to know where to focus his binoculars.
Could
you see a plane with a wingspan of 180' from directly behind from 27 miles away?
Or was the magic smoke that the flight crew in the Lockheed couldn't see making the object more obvious as it hung in the air in a trail heading out West nearly at right angles to the Lockheed.
So he "started to focus", implying getting in position, locating the object in the field of view, and turning the focusing dial until the object came into focus ... and by then the object was moving "behind the first layer of haze". This haze it was moving behind could easily have been the dissipating smoke trail, now thinned out enough to reveal the magnified receding aircraft.
Nope, the Lockheed flight crew report no smoke trail. They do report layers of haze and a few clouds.
You know when you look through binoculars and haze in the atmosphere is exaggerated? You know if the object was much bigger and much further away than he could tell, it would look extra hazy through binoculars?
You know if it was a jet plane heading on a roughly Westerly course at only 225mph, it would have been at least 27 miles away by then? Even further away if Johnson had had to stop to put his shoes on (you didn't theorize whether he would be wearing lace ups or slip-ons so we have no margin of error for that part)
Can you see a plane with a wingspan of 182' through 8X power binoculars if it's 27 miles away from you?
So to answer your question ... Yes I really am thinking it through, and you can park your demeaning innuendo that I'm not.
But as I keep pointing out using actual numbers,
you're not thinking it through. You're making it up as you go along.
If you were thinking it through, you would have all these calculations and you'd know it's not possible. If you could refute my calculations with anything more than excuses disguised as "perhaps" or "maybe", then perhaps you'd maybe post some actual calculations with some actual numbers so we can quantitatively verify them.
