Marcus - if it was originally published in a magazine such a popular mechanics, etc you might be able to do a library search to find the article. When I was in high school & college the library had these reference books you could look in & pretty much any subject you wanted they listed all the magazine articles ever written about the subject - now they all do that by computer. Back before EAA put the Sport Aviation archives online my sister got some articles for me thru interlibrary loan this way.
