sorry for this non-word post, but I've been trying to find something for quite some time, and I thought maybe someone here might be able to help.
as a child in the late 60's and early 70's in the US, we were shown documentary films about various scientific topics and large-scale building projects such as the Hoover Dam. these were on 16mm film and the general memories I have of these films are so strong, that I'd like to see if they are available on video or DVD. I seem to remember them being produced by Bell Laboratories, or some such company, though it may have been NBC, or another network. The Hoover Dam show had a theme song that sang "They Said It Couldn't Be Done" with a stirring melody.
anyway, I've searched with every keyword and phrase I can think of, and only come across one reference to a Hoover Dam video, with no indication to the producers, etc.
does anyone else remember these films?
feeling a bit sentimental...
