My best old book is "Ship Form, Resistance, and Screw Propulsion" by Baker, written just after WW1 based on all the work that had been done at the Froude testing tank. Readable and interesting (given that I'm into battleships).

Just received a box of books from recently retired engineer and low and behold if the all the books had my name on the fly. These books had disappeared over a period of few years when I was working with in the same group with him. No note of thanks or explanation. The problem is that the majority were quite expensive to replace.

Here are three sites that you probably have. My interest was the dud torpedoes in the early part of the war. We had a neighbor who was a navy chief and torpedoman when all the problems were unfolding. He had a lot tales about the bureaucracy and nobody listening. Nothing changes.
My boss when I was a co-op was an expert in the metallurgical aspects of armor and had worked both for the Army and Navy during WWII.
My father worked on all the shafts for the American Battleships built during the runup and during WWII. He ran the press that put bushings on the shafts.
The Battleship Alabama in Mobile,Al. took on a list during Katrina. There were quite a few people on her during the storm but haven't heard any stories.

unclesyd & GregLocock - I have a "present" for you. An article on the WWII torpedo problem from an out-of-print issue of American Heritage Invention & Technology. Have scanned, .pdf(ed), and upload a 1.4 MB zipped file to this link
Right click the mouse and select "Save Target As..." to download to your hard drive. Then unzip as usual.

Thanks for that. The development of torpedoes is a fascinating one, to my mind.

Have looked at it yet as my Winzip.exe has disappeared from the hard drive. I'll have to get another installed.
Thanks also. Anything I read about the problem conjures up memories of discussions I had with our neighbor. Nearly everything I read or see on TV about the problem makes his recollections much more relevant and to the point. Just wish that I had a tape recorder in those days.

UncleSyd,
It's frustrating when your personal books go missing isn't it. I write my name in permanent marker down the open side of the book (opposite side from the spine - not sure of the proper name). The only way to remove it is to sand or plane it off. An old colleague used to do the same, but included the words 'stolen from' and his name. It is a shame to vandalise books, but I find mine either come back themselves now, or at worst it is easy to identify my property lying on the desks and shelves of the lightfingered.
----------------------------------
One day my ship will come in.
But with my luck, I'll be at the airport!

I too have bought books over the years to help in my job. When folks have asked to borrow them I always used to say 'Ok no problem as long as you return it'. One day I caught someone photo-copying pages from one of my books. I went ballistic, I spend good money on a book and some b...d makes permanent copies for free.
That really ticks me off!
After that I took my books home and only brought them in to work as I needed them. Sometimes its a bit inconvenient when I need them and they are at home but it helps me keep my cool.

I just got "The Weapon Shops of Isher" by A. E. Van Vogt.
Dude, turn the guy in to the bean-counters for wasting paper (and time and electricty and toner and wear-and-tear on the copier) if he spends the several hours copying a 500-page book! And if he takes the book to a discount (five cents per page) copy center, he's just spent $25 + a few hours when he could've spent the $100 or whatever and gotten a better copy and more value for his time. (Shoot, Blodget's books only cost $10 apiece!)
I make copies of tables, examples, figures, etc. out of my and my office's and my coworker's books all the time; if it fits in my design calcs, then that's the right way to do things! I also write - in ink - corrections to author's mistakes, code updates or other notes in older (but good-er) books (e.g, Teng, 1962) - but only if the book belongs to me personally or it's the office copy. That's also the right thing to do.
Frankly, I resent it most when I've thrown down my $80 for a new book and I find spelling errors, computational errors, missing figures, a missing sentence/paragraph (AISC ASD 9th - bearing stress - I didn't have the errata for years!) inadequate indicies and appendicies, and worst of all, if the book is nothing more than a compilation of references to other works!
When it comes to lending books, only get steamed if the lendee decides to put your book on his shelf. And ALWAYS put your name prominentley, premenently on the inside cover.

I think there's a 2nd book "The Weapons Makers of Isher" though that may just be the UK title.
I've certainly got two Weapon shop paperbacks.
How about "The Oscillaton Valve. The Elementary Principles of its Application to Wireless Telegraphy" by R D Bangay, 1920.
And "Induction coils: How to Make them, use them & repair them" by H.S. Norrie, 1909.

I recently read "Blind Trust," an expose' on the conspiracy of complaceny in the airline business. Deregulation was a bad decision in 1982. We have had airline mismanagement, many accidents directly connected to dereg, FAA complacency, and other horrors in the airline business.
Interesting, but erroneous conclusions. Mismanagement cannot be prevented by regulation. FAA complacency cannot be prevented by regulation.
Boeing lost 4 DC-10's in a span of about 3 yrs, prior to deregulation. At least two of them were due to poor maintenance and subversion of required maintenance.
Stupid people are as stupid people do.

They never clarified why the rear baggage doors could not be easily secured. When the DC-10 first flew, there was whispering in the business about the rear engine wagging the tail. I flew in the rear of several DC-10's and experienced about 2/sec vibes.
Now when you look at the rear fuselage with the periodic torsional load imposed on top of the tail cone, then you can see that panel elements are being periodically sheared in both directions. The shears travel around the fuselage. Unlike a wing pylon that is tied into the wing spars, the DC-10 tail "pylon" is mounted into the flexible tail cone. There must have been permanent deformations because baggage handlers had trouble closing and locking the door.
