Someone who I find usually reliable, wrote me that "James A. Bass" was not a "certified engineer" in Florida.
If he is licensed, and he stays in this racket, I predict he will not be licensed for long.
Seriously, getting mixed up with someone who crosses the FPBE is not good for your career. That is to say, your livelihood. Author and civil engineer Samuel C. Florman once pointed out that engineers seldom cross the line and seldom do unethical things because they are afraid of having their licenses yanked away. Not because they are inherently good people. They would go from having an upper-middle class job to working the night shift at MacDonald's for the next 30 years.
Who would take that risk? Rossi would have to pay millions, up front, to persuade a real engineer to falsely back up his claims.
University professors, on the other hand, can publish anything they want. They are not licensed. No one checks, and there no consequences for being wrong or saying there might be a mezzanine heater. A professor might be thrown out for plagiarism or -- these days -- for having sex with an student, but publishing nonsense is fine. As it should be. That's the price we pay for academic freedom.
