San Diego's Fireworks Show Over In 15 Seconds 241

First time accepted submitter fotoguzzi writes "Garden State Fireworks is investigating how the entire Fourth of July show was launched after a signal was sent to the barges that would set the timing for the rest of the show after the introduction. Can anyone suggest how such a trivial step could go so disastrously wrong?" It's not the first time such a thing has happened, either.

      Awesome 15 seconds, but 30 minutes of driving, 15 minutes to find a parking spot, 30 minutes of waiting, 1 hour of fighting traffic to leave... (the better viewing places get overwhelmed with people on the 4th). I'm sure some people were bummed even though It would have been awesome to see. I bet there's a few people who were looking the wrong way too.

          Welp, I don't normally respond to a cynical mod-down, but I'm dead serious with this one.

          Lets face it, we all draw a line somewhere when we decide to attend something, right? I won't drive toward the beach (bay area) after 9am or so because that's when traffic becomes molasses, or stand in a long line for a slightly faster phone, or anything like that. Other people will. It takes a certain personality type to have the willingness to do so and I don't have it.

          The intent of the above quip wasn't to disparage those who do, but I can only imagine that if I'm the impatient type who times recreational activity around minimal wasted time (traffic congestion, staring at loading bars, waiting in lines), those who are willing to do these things are either
          A. much more laid back, or I suppose...
          B. doing it for their kids. Maybe I should've mentioned that before.

          In either case, a laid back person would think it's funny. A kid would think it's awesome. Kids haven't developed the sense of aesthetics needed to appreciate the rhythm and choreography behind the display -- they're just thinking "awesome, big explosion! Do it again!"

          So if you're so pissed off by my statement that you feel the need to hit Underrated in the popdown, maybe you're not laid back enough for such recreational activity. :P

        I have designed the electronics and software of a fireworks firing system for a company that does regular shows here in Catalonia/Spain.

        Believe me, experienced people are very cautious in everything they do, but unexperienced people can make big mistakes if they are overconfident in a black box system that will do everything for them.

        In one point specifications said:

        -The firing system must make an autotest for each circuit for the team to check all connections are in place.

        They test the firing circuits of the fireworks several times before the show to fire all the material. In our case it was done exciting the fuses (sorry I'm not native english) with a safe very low current to see if the fuse is electrically present, and the inspections does a check of a circuit every 0.05s, so you can check the entire show in a few seconds.

        For me this seems the check was done with full current on the circuits which fired all the fireworks during this test procedure.

        It's quite surprising to have someone design a system that lets this happen from my point of view, in our case we made the circuits impossible (due hardware to redundant hardware switches and circuits) to excite to fire during the test (there are various physical limiter).

        So... it seems someone who had not enought experience with fireworks managed to build his system and convince this people to use it... but its surprising, it's a pretty conservative people, at least the ones I know.

  • FIreworks displays always run too long, that one sounds like it would have been great.

    You could set them off over a period of 15 days, or 15 hours, or 15 minutes, or 15 seconds. How does is not get better as the time reduces?

    • I think a white ball of fire and smoke seems a bit boring. And judging from the youtube videos, it was.

      There's craft in doing a good show that's exciting enough, but also long enough to be impressive.

      You're right though, some try to spread too few fireworks over too long a show by choreographing it all really thin.

      Not always. Most customers (the folks who pay for the shows) want the longest show for the least money. I've worked show where we were launching one shell every three seconds in order to meet the show duration requested by the customer. Think this turned a nice 5 minute show into a painful 30 minute experience.

      How does is not get better as the time reduces?

      As time reduces you approach what we call a sky puke. Okay it's a lotta boom but, you really don't get to see much.

      Depends on the show. Those that are simulcast to music might have limitations on when/if they burst. Also I've done/seen shows that does ground effects at different times.

      Generally the budget I've seen is for a small city, one minute == $1000. Depending on the pacing at least one shell is being launched every 3rd second. That's 20 shells minimum if there are no multiples firing at the same time. $50 per shell including labor materials, other costs, etc. is what it boils down to. For a 30 min show, that's 600 shells.

            Also, Los Angeles skyscrapers are a tiny island surrounded by an ocean of single family homes. They don't tower over the city, the city expanse dwarfs the skyscrapers.

    Maybe the timings were in milliseconds instead of seconds (or a new version of the software suddenly thought they were). Now, 30 minutes of fireworks gets done in 1.8 seconds. But since fuses take a couple seconds and some are longer than others, you get a total of 15 seconds.

They decided to shoot everything off at once, one after another; fireworks, thunder claps, lightning, all at once. It was totally awesome.

    Electric matches on the circuits take 5 milliamps to ignite them.

    After the fireworks are loaded and wired up, testing is done to identify matches that aren't wired up right. Is there a chance that the testing process failed. On computer systems, it is pretty automated and happens fast. If the test resistor wasn't in the circuit properly, it might look like that.

      Electric matches on the circuits take 5 milliamps to ignite them.

      That's a bit low (see: []). 5 mA sounds like the test current.

      It's going to be an interesting investigation. Most modern pyrotechnic controllers incorporate a shorting system to keep the squibs from being fired inadvertently by static electricity or single point control failures. To fire each circuit, the safety shunt must be removed and then the firing voltage applied. That's two failures at the lower level of the controller. And on every circuit simultaneously. I doubt it.

      From the video, it appears that the fault was common to three separate sites. They almost certainly used (at least) one controller at each location, tied together through somee communications network to a central control unit handling the timing. My money is on a software failure at that central point.

        Agree on this. This is a test procedure with firing currents instead of test currents.

        In our case our circuit tested the whole show in just a few seconds like this (each match every 0.05 or 0.1s). So if firing current (>>100mA) was applied a faulty test would do this.

              Depends on your pyrotechnics people. When I lived there Traverse City, MI, used to go withe the lowest bidder for their Cherry Festival fireworks. We lived two blocks from the National Maritime Academy pier where they launch from, and would walk down and watch the fireworks from the park there. In either '95 or '94 the bozos they had contracted somehow trashed their control board and proceeded to run the whole program by hand. This consisted in a guy walking up and down the pier with a FLARE setting off random fireworks in no particular order.

              This was amusing to watch, and even more amusing to hear the idiots nearby commenting on how wonderfully they were choreagraphing the fireworks to the radio station they were listening to, until all of a sudden the guy tossed his flare in the water, covered his head and ran like hell. A few seconds later one of the larger shells went off **in the mortar**, showering us with sparks and setting off a dozen or more fireworks at once. That turned out to be our "finale", except for those of us who were close enough to the company's trailer and got to listen to the worker tell his bosses to go fuck themselves because he was NOT going back out on that dock with another flare.

              I think they've abandoned the lowest bidder habit, at least for the fireworks display.

                I'm a licensed pyrotechnician (FPO) in Texas.

                (Hand-fired) reload shows are still done to this day, mostly because they are cheaper and the customer naturally wants to pay as little as possible. It's also how it was done when my grandpa first got into the business in the 50's.

                The last two shows I did were reload shows, and yes, it is basically just the shooter walking up and down the line of mortars buried in the ground touching a fusee (a.k.a. road flare) to the quickmatch fuses. Running behind the shooter are his helpers with armloads of live shells, dropping them down into the empty mortars that often still have smouldering paper in the bottom. It's quite a rush, and although I personally prefer an electronic show, there are plenty of adrenaline junkies who won't do anything other than hand-fired shows.

                Starting in the 70's you would see shows fired electronically, with a master control box where the shooter hits a switch for each shot in the show. This was the era when choreographed shows starting becoming possible. Many shows are still done this way. Nowadays lots of shows are computer-controlled with a laptop and an RS-232 (or other) connection in place of the shooter and switch panel.

    A am a pryotechnician that works exclusively with computer fired shows. From what I'm hearing on the mailing lists so far, they were using the Fire One controller. We also use them (we have over 100 modules at $795 each). I haven't been involved in the "Loading" of the show into the embedded controller for the past few years, but I was called into action about 3 years ago when we had the same problem with our "semi automatic" shows (press a button for each event). I found there was an additional step when downloading the show from the PC to the firing controller called "Assign Delays" that had to be manually entered when loading. Without that step, all shells for each event fired immediately. I don't know if Fire One ever fixed it because it's now part of our written checklist for loading and we haven't had a problem since, and Fire One is notorious for fixing a problem with one customer, updating the firrmware but not telling the rest of their customer base that there is an update.

    If you are using Fire One, you can thank me for the new Line receivers in the new modules, I had to go to the plant and show them the problem.

      Glad I'm not the only one that does that. Our emails to customers typically go along the lines of "this update contains several changes and bug fixes, some of which you might notice."

        While looking at their web site I found this quote:

        "FireOne is the only system in the world capable of firing multiple firing modules and multiple cues completely simultaneously - zero time dispertion between firings. The system can simultaneously fire any number of Firing Modules"

          Yeah, Don't get my above rant wrong, Fire One is the best system, really the only system out there for firing large shows. I use all of the others, but they are the only ones out there that can handle large pyromusicals (I.E. > 2000 cues).

          It has more then enough juice to fire an entire module (32 cues) at once, and that is a good thing for mine fronts, set peices etc... We need and want that feature.

          I'll be back at the magazines tomorrow and want to run a test - I'm thinking if you either forget to assign delays, or assign them twice for a fully scripted show, you will have the same result.

          As far as I know, there are no commercially available products out there that will let you test ematches with firepower on (the Capacitive Discharge circuit) powered, so I'm pretty sure it's not a testing issue.

          Even though Garden State is a competitor, I feel for those guys, We've had our share of learning curves too.

  • I wonder if they were thinking minutes but programming in seconds.

    All they needed to fix it was a bunch of people dancing around really fast. Nobody'd notice.
