....it was only between 5000 to 7,000 feet altitude tops... and if the next question is "How Do I know the altitude" I was in the Army.. Air Cav .. I flew enough to be able to judge altitudes accurately.

Can you please elaborate on how you judge altitude of cruising aircraft?
.... it is already established fact. Why don't YOU know that?

NO, it wansn't at "5000 to 7000 feet". Doesn't matter your army experience....does it match my almost forty years flying the darn things??
I had to struggle, with the few split seconds when you had zoomed out (and held it steady)....it was obvious, by comapring to the other contrails, and by the relative speed as it crossed the sky, that it was well high enough to make normal contrails. IF it had been below 10,000 feet, would have been at maximium 250 knots....but, still that is fast enough that you'd notice a distinctly faster motion across your field of view. Problem is, as you zoomed in tight, all relative motions clues get smeared...and it LOOKS like it's going faster. Illusion.

Fade away? Like the "contrails" that you are breathing?
I have been around a long time, probably old enough to be your daddy, yet you have so little respect.
Tsk. tsk.
Ignorance can be forgiven, stupidity, not so fast. I assume you are not dumb...you can spell.
You are so fast to discount what others assert to be their experience, confident enough to tell them they are mistaken...YOU can explain it all.
Not even Einstein could explain it all, and I believe he was Jewish.

I'm far from an expert on the matter, but from a brief read up, it's not so much the altitude, but the temperature, it needs to be -40c to super-cool the exhaust from the aircraft to turn it into ice droplets and form a contrail. So if it's -20c on the ground, hitting -40c wouldn't require much altitude, would I be correct in assuming this?
BTW, I found this amazing (IMO) contrail pic from above, clearly coming from the planes engines.
