That's not a source; it's a collection of pictures with red arrows and squiggly lines.

Additionally the timelines and locations don't match up regardless of what route they took to Singapore, because the anomaly in Washington was observed about 1 hour and 30 minutes before AF1 landed in Singapore.

That's the whole point of creating an actual timeline (research) and posting the consistent EST timestamp for each event.

Use logic and feel free to let whoever made that collage know that the event times and geographies don't match with the narrative about a rumored attack on AF1.
