No matter what the accident or disaster is, you will always find some "expert" who disagrees with official findings. Sure, sometimes they might be right, but the other 90% of the time they're wrong. Right now on the fringes of social media TWA-800 is making a comeback in the CT world. For the past ten years there has been a fringe element claiming Titanic sailed with an ongoing fire in a coal bin, and that was the true cause of her sinking. Youtube hosts dozens of aviation experts ( or as I call them: Pilots who have a drinking problem) who make judgements on video footage, no matter how poor the images are, and then spout off about how the FAA and the NTSB are getting it wrong even though the wreckage is still smoldering. This has been the nature of the beast going all the way back to sitting around the fire in the cave.
There are a few, vocal, people just hard-wired to see a conspiracy in everything.
This is a game to CTists. They're smarter than you because they can see the hidden truths of the world, and if you have the nerve to debate them you're either a fool, or a shill for our overlords. Only their facts count. And they weight the game by asking question about peripheral aspects of the accident, and then claim coverup because those questions are unanswered in the various investigations. In this case the bow visor was knocked off in rough seas because the ship was sailing too fast, and the structure was never designed for open ocean transit in the first place. The JAIC never addressed the location of the captain, or the contents of the car deck because neither have anything to do with the sinking. This should be obvious. But the game is to cloud the field with ghost stories about spies, smugglers, intelligence agencies, and political intrigue.
I used to be a CTist, I used to play this game. And unlike some, I think I was good at it.
I could bury you in irrelevant facts and build bullet-proof strawmen. I did it because I believed what I was saying...until one day I didn't. The real world is impossible to get around. Fact, unlike CTs, don't change. Those who initiate CTs claim to have done research, and have insider knowledge, unnamed sources, and so on. We who buy into CT's just assume they have done honest work, and the fact is they almost never do. The CTist's job is to sew distrust of various institutions, and in some cases it has worked. The result is people only believe the other side of the argument because the officials are corrupt. Forget the fact that every ferry disaster started in the front office (a real conspiracy, just not the sexy kind).
Not every question needs or deserves an answer. Investigations cost money, good investigators are expensive. Chasing every claim down is unrealistic, and from the few accident reports I waded into it seems like most investigations are much more comprehensive than the CT world gives credit. For the most part the unanswered questions came for CTists in the first place.
Now as an ex-CTist I am comfortable with ambiguity because it doesn't change the root facts of the case.
