re: #194 bloodstar

You realize that’d be physically impossible to see? assuming that the plane was flying 5 miles up, the curvature of the earth would conceal the contrail at just under 200 miles. If the plane is flying lower, you that number drops quickly (under 180 miles for 4 miles up)

It’s not thousands of miles, I promise

Well I was referring to the thousands of miles in terms of the earlier ruler and basketball analogy.

So let’s say from the altitude of the chopper, the distance to the horizon is something like 100 miles.

1. Contrails from jets aren’t that long!

2. Contrails from jets aren’t shaped like that. It is clearly conical from the light and shadow.

3. You see the engines of the bird!
