You've already gotten your answer to that question ~ it came down to warmer air, the contrail ended, the plane landed at Ontario, not LAX.

And the Helicopter pilot with a professional zoom camera could not see a plane flying at a low altitude. Right. So let me see if I get your changing story line. You now are certain it was the UPS flight landing at Ontario ?

Do you have any idea where Ontario airport is?

I do.

It's out there East of LA. LA is a very big city.
