Big words for a guy whose own figures are off by 8 years.
I hate to say it, but not only are your figures are quite off, you have fallen into the specific trap of misguided thinking that both I and the comment I was responding to was making.
The level of technology reflected in a design is determined by the date the thing was *built*, not when it finally failed. Going to the comment I was replying to, you have just implied that an antique Studebaker that crashed this year represents the cars of 2015, and thus all current cars are unsafe as they lack air bags, seat belts, and crumple zones (in the last few years of the company they added the new innovation of the roll bar to the Studebaker Avanti, but most lacked even that).
The Hindenberg was built 79 years ago and crashed 78 years ago. It was built with technology of 79 years ago, not the technology of the following year when it crashed. There's a five year wonkiness in there involving bankruptcy and Nazi funding, but I went with the date of completion rather than the laying of the keel to match the other figure.
Chernobyl's reactors were designed, built and then the first came online in 1977. As they were all designed at the same time and built in a short period of a few years, they presumably all reflected the technology of that year, 37 years ago. When the disaster happened, they were not the technology of 1986, any more than that hypothetical crashed Studebaker reflects this year's car safety standards, even if you do safety retrofitting: that gets you seatbelts, but not some really fundamental things like crumple zones, roll bars and countless other basic improvements made to personal vehicle technology.
Which, if you'll read the comment I was responding to, was *exactly* the point being made, the one I was echoing, and the trap of thinking you fell into when reading my comment. That does indicate how pernicious an issue it is.
