There is zero way you can figure out someone’s motives for using a callsign that just so happens to be involved in a crash. I’ll just go over why they could have a callsign of that sort:
- They don’t know that it was involved in a tradegy to begin with.
Self explanatory, we all are very well aware of the tragedy of 9/11 and what it involved, flight numbers I personally do not remember which ones were involved in crashes, the ones I do know are from extremely major and well taked about accidents, and I doubt many others remember a bunch of flight numbers just so they can avoid and not be called out for potentially being ignorant towards an accident they didn’t even know happened in the first place.
- May be a real-world flight number.
I don’t need to explain. I can see many people using a coincidentally crash-related callsign because they’re trying to be realistic.
- Paying Tribute
Many have said this already. There are people who do tribute flights in remembrance of tragic accidents. May not be common, but definitely possible.
I wouldn’t blankly assume that they are using that callsign just for the sake of ignorance. It could be any of the above reasons, which is why they get glossed over and mostly ignored. Thank you for coming to my TED talk.
