Where can I see the air traffic history over a specific geographic area?
Yesterday between 4:20 - 4:30 pm local time, I observed over the city of Tijuana two planes leaving trails that were flying north-south in secant lines, the two planes were about to meet but at the last moment one of them detour to the west.
I didn't have my phone at that moment to take a video or photograph, so I leave this drawing of how to observe the situation.
