I just don't want to venture "way out there" deep into any of the conspiracy theories people might dwell into, and there are plenty of those, I just wanted to point out how strange this crash was that resembles the Airbus crash in the Alps and the Malaysian 370 from which we had never retrieved the black box probably lost forever if they ever find the wreckage.Regarding past airplane crashes… We usually only get the official explanation of what caused a crash, but never know what really caused them. The airline industry is known of having veiled the true reasons for quite a lot of crashes in the past. A classic is design failure. The way they handle these things in the 70s and 80s was called “tombstone politics” (it required deaths in order to finally change a serious design fault). Crashes were considered “the cost of doing business”. Very cynical… The kind of sociopathic attitudes common in big businesses.
If you refer to cutting edge technologies in relation to big business, obviously any big corporation for profit or state owned enterprise would look into any possible ways to cut corners, cut operating costs in the ever increasing competitiveness especially in the airlines market share, that includes supply chain, maintenance costs, etc down to pilots errors to save fuel, meet impossible schedules, loss of mental alertness, all for getting flight credits etc, the list goes on and on, the bigger the enterprise is, the harder it is to oversee and regulate the standard operating procedures per the company's code as licensed by their respective state. There is also one common trait we all human share which is called laziness you know. The reason why we see much less fatalities per flights a day is because we had learned from past mistakes, with the exception of the MAX fiasco which was solely on Boeing, lawsuits were brought against them. One might say, hey, but we want Boeing out of the Chinese market to send a message to Beijing not to help Russia in the war etc, you know. If you start thinking that way, you may start believing in mirages, even though they might turn out true, but the confirmation bias will always be there even if proven wrong, there will always be elements of a doubt that can cloud the objective reality as it is.
Majority of reported accidents in the past were reasonably explained after months or even years of investigation, actually a lot of those were contributed to pilots error, makes sense, there is a reason why there are at least two pilots on each commercial plane. Heck, even Titanic was considered a technological marvel, the unsinkable ship until they found out it was not, but too late. Even the Soviets in the early days of their aviation industry had suffered a lot of losses.
