How the Sinking of the Titanic Sparked a Century of Radio Improvements 99

joshuarrrr writes "When the RMS Titanic scraped an iceberg on the night of 14 April 1912, its wireless operators began sending distress calls on one of the world's most advanced radios: a 5-kilowatt rotary spark transmitter that on a clear night could send signals from the middle of the Atlantic to New York City or London. What the radio operators lacked, however, were international protocols for wireless communications at sea. At the time, US law only required ships to have one operator on board, and he was usually employed by the wireless companies, not the ship itself. On the 100th anniversary of the Titanic, IEEE Spectrum looks at how the tragedy accelerated the improvement of communications at sea."

      SS Californian was close enough to see her emergency flares.

      • Indeed, the Californian sent a warning before the collision and the Titanic's captain ignored it. The only real injustice was that the owners should have gone to prison for corporate manslaughter because they insisted on him sailing at night in icy waters. The Californian had stopped.

        The root cause of the Titanic disaster was, in fact, free market capitalism. (The people who down-mod things they disagree with, instead of responding to them, may now proceed as usual.)

And as for reliability, our EMI 1000 one kilowatt parallel-transistor driver was, by far, the most unreliable component in our otherwise mostly tube chain.

          I understand that you have a meta-complaint and/or political viewpoint that suffuses your worldview, thus everything gets translated through that filter. Granted.

          But:
          First you say that the CAPTAIN ignored the warning. Then you say the OWNERS should have gone to prison for "insisting" on him sailing at night in icy waters.

          Is there proof or merely inference that the owners directly ordered the captain to make this call? You might say that "capitalist" motives caused the captain/owners to make bad judgement calls, but to then hyperbolize that into a blanket indictment against free-market capitalism seems at the very least specious.

          I know that my mere questioning of your point has already probably painted me as a 'crony capitalist' and thus you've probably stopped reading. But your logic escapes me; by that same token Midas' story was also a criticism of 'free market capitalism' long before such was even formulated as an holistic concept.

          Doesn't it ipso-facto follow from your assertion that people in socialist, monarchist, or other (non free-market) economic systems are contrariwise immune to the all the sorts of motivations that could make a captain of a huge ocean liner make errors in judgement? (If it logically was the "fault" of free-market capitalism, removing it from the situation would have made the accident impossible.)

        • It is so good to know that no communist, no socialist, no dictator has ever, ever, ever made a bad decision.

      • I still don't get why they didn't respond. The documentaries I've seen pretty much said the captain asked what color the flares were each time he was told about them, and then did nothing. Was there something wrong with the flares' colors?

        Oh, and why were the watertight compartments open at the top? What purpose did that serve?

        • They didn't imagine the listing of the ship would cause the water to spill over. They figured a few feet below the waterline was safe enough. After the Titanic sank they eventually requires watertight compartments to traverse the width of the horizontally to allow water to flood evenly up to a certain point, preventing complete sinking and allowing for rescue.

      The ship was designed to carry enough lifeboats for everyone, but the company didn't fit them because regulations didn't require it. If I remember correctly, the Titanic was the first big ship to sink where the passengers did stand a decent chance of survival in lifeboats precisely because of radio; if you'd sunk twenty years earlier the odds of being picked up by another ship were small even if you had enough lifeboats because the other ships would have no idea of where you were.

        Whalers lost thousands of miles from any landfall were able to navigate to South America decades before. IIRC, Captain Bligh had a lifeboat about the same size as the ones on the Titanic, even earlier, and made his way home. You do not need your lifeboat to be picked up at sea, that just makes it easier. OTOH, there was almost no chance for the passengers left swimming, unless lucky enough to be fished out of the water by one of the lifeboats.

      Really? This is based of anecdotal evidence. This statement means nothing. I can think of many ways that the government has regulated things that haven't caused death, but that's as good as saying that they haven't. Here's a more pressing question - at what point should a government step in to regulate something to prevent death. if it prevents the death of 10 people? 100 people? 1000 people? Is there greater benefit in not regulating as the number of people who are killed pales in comparison to the trouble that regulation would cause? Accidents will happen, people will die. Not everything is done without reason. A lot of it is playing the odds, and sometimes, people lose.

          In a way they were though. British shipping was the *the* shipping around the world. When you moved thousand upon thousands of people by ships (think modern airplanes) people care very much that they're safe, that was after all, how people emigrated by the hundreds of thousands. The "RMS" part was Royal mail ship, as in they expected any ship with RMS in its name to meet government standards for how quickly it got to destinations and got things loaded for the royal mail service. These were all really big deals before aircraft and modern radio communications got the job done mostly better.

          I'll grant you that the navy, especially at this point the Royal Navy, which was larger than the next two largest navies combined (and those were france and germany) and operated over the whole world, all the time cared very much about communication. But even as the article points out, they had the technology on the ship at this point. What they needed was to understand how to use that effectively.

          The Titanic highlighted what *could* have been done, given the technology (including technology on the ship) if there had been systems and procedures in place. Which is much like aircraft, if someone breaks into a cockpit and crashes a plane, everyone wonders why we don't have reinforced cockpits, why we have gps on aircraft etc etc, because an airliner landing at the wrong airport, or an airliner crashing due to bad weather that could be dealt with by automated systems very much drives adoptoin. . Ocean liners that carried thousands people, vital food supplies and the masses of the public (rich and poor) were very much in the consciousness of people wondering about moving overseas or having their families from europe follow them. The military, the royal navy in particular, had functioned for 300 years without radio, and had systems and procedures in place to act on their own initiative without orders from London, and to act in the best interest of the crown. But the titanic highlights what was, at the time, all of the things that could have been done with what they knew then, but weren't using effectively. They didn't try (and fail) to build the ship as unsinkable, or with a radio because they didn't vaguely appreciate that these were good things. They just didn't understand quite how to use them at that point. The navy got its lessons at Tsushima and Jutland, the army its lessons in the boer war.

      It isn't clear to me that KAL-007 was a genuine navigational error. Marconi's RDF was good enough to do precision-bombing and instrument-only landing in the 1940s. It is entirely possible that navigational aids 40 years later were indeed inferior, but even if true that's not through a lack of capability but a lack of wit. I'm not inclined to believe the conspiracy theories that the pilot was paid by the CIA to trigger the USSR defenses (the CIA haven't been competent in anything else, so there's no reason to believe they'd be able to accomplish such a task). Nonetheless, staggering errors of judgement were made by the pilot, even given all the other staggering errors of judgement that had led to pathetically sub-standard navigational aids.

      Ultimately, however, this is true of most other disasters - be it the R101, the Titanic, the current global economic meltdown, Fukoshima or any others you might care to name. The problem can almost always be traced to a string of errors, stupidities and absurdities, ALL of which had been known to be errors, stupidities and absurdities AT THE TIME. In other words, gross negligence -- usually, but not always, accompanied by bean-counting. The disasters do NOT lead to solutions, the solutions already existed. The disasters lead merely to the accountants being ordered to loosen the purse-strings. At least for that week.

      (The recent sinking of a cruise ship with loss of life has led to the discovery that modern passenger ships also lack sufficient lifeboats - and are also horribly unstable once they start shipping water, leading to half the lifeboats they do have being unusable. This is a repeat of the situation leading up to the Titanic. It exists not because people don't know how to build lifeboats or count passengers, but because decisions are made according to profit margins and not according to rational examination of cause-and-effect.)

      History does not repeat itself, but accountants do. You can't avoid making decisions based on some economic philosophy, but it is self-evident to anyone but the determinedly blind that none of the economic philosophies out there are very good at risk management.

While instrument-only landings did occur, that's after one already knows one is in the right vicinity and is making the right final approach on instruments.

      The KAL-007 tragedy is unlikely to have been pilot error.

      Pilots are in many countries rewarded for saving the airline money: prinicipally by picking good routes and saving fuel (about the only performance incentive available to pilots). This was true of JAL at the time.
      A practice had developed of "accidentally" traversing USSR, etc. airspace, taking a shortcut to save fuel.
      JAL 747 pilots had developed a reputation for doing this.

      It was believed that the US had spotted this trend, and was using it to sneak reconnaissance flights over the area by piggy-backing them on commercial "flight routes" and timetables: flying ELINT aircraft with commercial tags.

      The Russians now believed that JAL-007 was really a US elint aircraft. They screamed blue murder over the airwaves, warning the flight that they would shoot. JAL-007 had its radio turned off, so that it could claim it was "accidentally" in Russian airspace, and so missed the warnings.

      Hence the tragedy.

      A lot of this kind of subterfuge happened during the cold war.

    I was about to spout my mouth off, but figured I'd read the article before I made a fool out of myself. But the article didn't have anything, so here goes.

    The Titanic was near another ship - the Californian could have made it in time before the ship sank, but the radio operator went to bed. In those days, there was no requirement for 24/7 manning of the radio station, which was the single largest thing to come out of the sinking (in terms of radio). It's hard to fault them for it, though, since radio was still pretty new. The next-closest ship that did hear them (the Carpathia) hauled ass, at great risk, and got there a few hours after the sinking. Radio, as a technology, worked. Again, since this was the event that basically defined radio as a serious method for emergency communications, it's hard to fault people for not realizing it in advance.

    Part of the rules for the calling frequency (500 KHz) was that everybody would stop talking for a few minutes every half-hour, so people could hear if there was a station in distress that was far away, or running out of power, and being swamped out by local traffic. Not an issue for the Titanic, but still a good idea.

    All in all, the radio stuff is interesting, but what the Titanic needed were more lifeboats and a more serious response by the crew and passengers. Even if the Californian had made it there while the ship was still afloat, there were thousands of people on that ship, no way to get them off, and freezing cold water so they couldn't just jump in and be pulled out.

      Well, the ship was built to carry as many as 68 boats. There was no reason it couldn't have had 30, even 60 lifeboats.

      Certainly not all of them would necessarily have been offloaded, and some people would have died, but as it was, the 700 people on the boats could have had another 400 just on the rated capacity of the boats.

    • 24/7 monitoring on a nearby ship was the ONLY change that would have made a difference, at least in terms of technology. As someone else pointed out, operators in NYC did hear the distress call... but what could they do about it? Hope the ship stayed afloat for a few weeks while they sent a rescue vessel? "Look, he wouldn't bother writing out 'glub glub glub', he'd just SAY it." "Perhaps he was dictating?"

        Aint so. The closest ship (SS Californian) would have been alerted had the Titanic had red emergency flares on hand to launch.

          Instead all they had were white signal flares which we know the closest ship saw and promptly ignored because they were the wrong color.

        • The Californian was nervous about what they saw (the Titanic making a hard port and stopping, the flares). They were nervous enough to attempt a signalling by Morse lamp, but it didn't occur to them to wake the radio operator, and for that they deserve flack. But check out my comment [slashdot.org] replying to your sibling - I ran the numbers, and it seems implausible that the Californian could have saved all, or even a significant majority of the people on that ship. There's no question their presence would have helped,

        • Instead all they had were white signal flares which we know the closest ship saw and promptly ignored because they were the wrong color.

          Doing a bit more checking flare colors were sorted out circa 1950s before that any color could be used. I'm sorry for my stupid assumptions.

        • I also have white flares on my boat. They are used to prevent collisions and for illumination. They are not a distress signal now and I think the color coding of flares was a result of the Titanic. Red = distress now. (and I have red ones too)
    • If Californian had gotten there in time, they could have used both sets of boats as shuttles, bringing passengers across. Ships generally have an accomedation ladder that can be rigged from the main deck to the water line to allow access to small craft of that sort which would have been a great help in evacuating the ship. And, even if that wasn't possible, Titanic's officers could have controled and organized the passengers, having them jump into the water when, and only when there was a life boat availa

        Hypothermia killed most people in the water within minutes, so that would've been a bad idea to risk.

        The ship sank in about 2 hours - for a lot of that time (about a half hour) they didn't really "get it" (which is obviously a huge problem as well), and for about the last hour, the ship was tilting far enough that rescue may very well have been impossible. If I were the captain of a mid-size steamer, I'd be very reluctant to be anywhere near an ocean liner whose stern was literally coming out of the water. In any case, even if the Californian had rushed directly to aid, it would have still taken almost an hour to get there (the Californian topped out at about 22km/h, and the Titanic was about 19km away). By that time, it would have been so clear that the Titanic was going down that the (much shorter and half-as-long) Californian wouldn't want to be taken down with it. Any assistance would not have been a direct ship-to-ship transfer, and they would have been stuck with ferrying boats around, which they only had an hour to do, or having people jump in and swim, which would have killed hundreds of people anyway due to the cold and the distance. Had they decided to ferry the lifeboats back and forth, they would have needed to either get the boats back up to the deck, or send a thousand people down on ladders one-by-one. And then repeat it all on the other ship.

        There's no question that more people would have survived, but it would have been more like a 50-50 or even a 60-40 split instead of the 32-68 split it was (save-lost). It still would have been a calamity of unthinkable magnitude.

        Bottom line, the Titanic needed more boats, and more urgency about using them. Everything else would have helped, but not enough.

        • Very well written and reasoned. I congratulate you. Californian would most likely have placed herself off to one side, well away from the stern, lowered her own boats and rigged her accomidation ladder if she hadn't set it up already. And, as far as hypothermia goes, that's why I specified that people would only be sent overboard when there was a boat ready to pick them up to minimize their time in the water. Yes, many people would still have died but not, I think anywhere near as many.

Not an issue for the Titanic, but still a good idea.

      To be sure, but Silent Periods (15 to 18 minutes, and 45 to 48 minutes, past the hour, every hour) were installed as a result of the Titanic disaster, not before, as part of the Safety Of Life At Sea (SOLAS) treaty series. One of the conclusions drawn from Titanic was that there was no universally agreed-upon prioritization of wireless traffic, and the SOLAS treaties established one.

      There was a SOLAS treaty of 1914, but World War I kept it from being ratified in most (if not all) countries and, though many countries implemented parts of the agreement piecemeal, the first ratifiable treaty wasn't signed until 1929. (Even then, the US did not ratify the treaty until 1936 -- with the Titanic disaster now ancient history, the depression gave a certain political party the opportunity to complain about onerous, burdensome government regulation taking jobs from otherwise employed sailors, and that treaty supporters were dupes of foreign powers trying to take the jobs of hard-working Americans by modifying the "free market" in their favor. Reading the political arguments of the time, and the reports of the congressional hearings, in the old newspaper microfilms is quite depressing -- and cynicism-inducing.)

    At least one ship heard the SOS and failed to respond, the main improvements in the aftermath of the tragedy is it became compulsory to respond to a distress signal.

    One of the under-appreciated technologies to result from the Titanic disaster was the development of the auto alarm: An automatic receiver that continuously monitored the calling frequency (500 kHz) for a specific alarm signal to be sent by ships in distress.

    Prior to this time, an operator trained in Morse code reception was required to be on duty or, failing that, a "wireless watcher," a deck officer trained to listen for the distinctive three-dits-three-dahs-three-dits of the SOS call. However, the wireless watcher system had obvious flaws (e.g., other duties of the deck officer taking him away from the receiver), and so an automatic system was desired. The trick was doing it with 1920s technology.

    It was decided early on in the development of the auto alarm that having a detector able to correctly decode "SOS" with sufficient sensitivity and selectivity (i.e., without false detections during a night of reception of multiple simultaneous and possibly interfering signals, lightning crashes, etc.), and at different rates and fidelity (recall that the SOS signal would be sent by hand, by a person likely to be under high stress) was beyond the technology of the day. Instead, a second, simpler, signal was invented -- a signal specifically for detection by the auto alarm. This signal was defined to be a series of four or more dashes, each four seconds long, with a space of one second between them. (Clocks provided in the radio rooms were required to have a sweep second hand, and a pattern of 4 on, 1 off dashes was printed around the circumference of the clock to aid the timing of the operator.) Alarm bells were placed over the bunks of both the Radio Officer and the ship's Master.

    When the radio officer went off watch, he turned the auto alarm on. Should an auto alarm signal be received, the bells would go off (not unlike a fire bell and, a foot over your head, very impressive at 2 AM, I can assure you), and the operator would then climb off of the ceiling, go to the radio room, turn off the auto alarm, and monitor 500 kHz to see what's going on.

    In an actual emergency, the radio officer on the ship in distress actually sends the auto alarm signal first, then sends the SOS signal. (The SOS signal, by the way, is sent as a single character, with no spaces between the letters -- di-di-dit-dah-dah-dah-di-di-dit, not di-di-dit-space-dah-dah-dah-space-di-di-dit.) This mp3 file [qsl.net], of an actual disaster (the fire on the MS Prinsendam, PJTA, in 1980), has this clearly audible: The recording starts with a long series of auto alarm tones, followed by the SOS call at about the 2:30 mark.

    Those of us with a logical bent would find the design of these auto alarms to be a study in stone-knives-and-bear-skins analog computing. This document [fcc.gov] gives one some idea of the requirements. It would be a good task for an engineering student project.

      BTW, at the time, CQD was the preferred distress signal, except among ships in the German Empire. The fact that sending a 9 code signal sort of like SOS is easier to do (especially when excited or panicky) or to recognize than sending three letters chosen because CQ is a pun on French and the D stood for Distress (as opposed to landline CQ, which was just a message for everyone) still took some time to sink in (yes, it IS blindingly obvious in retrospect, unless you are an experienced Morse Code operator,
