That would be me. Lots of people were talking about how shiny a silver plane is so I found a pic of the jet used for flight 808. Now that meme is gone and it's a white plane and 808 is history.
But even if these planes were reflecting aluminum, it would not explain the absence of clear space immediately behind twin airline contrails from engines on both sides of the fuselage that cools before those twin contrails fatten up and then merge into one.
That's true too. I have seen the sun reflect off of many silver airliners and it makes a nice crisp bright white reflection even in sunset/sunrise conditions. A very small point of light that isn't sustained because the jet quickly moves out of an angle that directs it to one point on the ground.
Yep. It's why someone relying on still shots as evidence in a contrail-looks-like-a-missile argument, lacks swaying power from the start.
