The track you see, and the actual track they are on- are two entirely different things, anon.
Routed on an airway that just happens to fly over the crash site. East coast airspace is ridiculously busy. They have canned routings to get you around the worst congestion on your way to the destination. This is normal. Not worthy of attention.
Right. Because they are going to route them through the busiest corridors on earth…."because we can". Bullshit. Risk management dictates a less direct route- hence off the coast and away from busiest arrival/departure corridors. I know this because I've seen it. Live. But keep making something out of nothing. Enjoy your rabbit hole.
