What's so different about it?
Seeing a pattern here...
1. It is completely illuminated instead of darkened on one side.
2. When the camera is zoomed back in each the first creates a much bigger profile in the sky and is thicker by comparison.
3. The second one makes a wide turn to the viewer's left as a plane coming in across Catalina should instead of arcing to the right.
4. The second one shows clear separate contrails for the multiple engines of an airplane.
5. The first goes down to the horizon, the second is entirely above and the tail of the contrail doesn't even look like it's pointing down to the horizon.
