The Unintended Consequences of a career in Engineering Or How to end up a mass murderer without even trying

The PATRIOT System, and my part in it – Anti-aircraft / ABM system – PATRIOT stands for: What am I here to talk about? P hased A rray T racking R adio I ntercept OfOf T arget

Here's what it looks like

First Gulf War Aug 2, 1990 – Feb 28, 1991 a.k.a Desert Storm In response to the constant air strikes, Iraq started launching Scud missiles first at Saudi Arabia, then Israel PATRIOT batteries were permanently placed around sensitive areas, manned and running 24/7, in case of missile attack Conventional high explosives were carried by the Scuds, but the fear was they would be armed with chemical or biological weapons

So what's a Scud anyway? Soviet built surface to surface missile Designed from the German V-2 Scud is the designation NATO gave the missile Came in various versions as it was refined over the years – Iraq had Scud-B, the most common one (about 7,000 produced) Can carry explosive, chemical, or 5-80 kilo-ton nuclear warhead 37 feet long 13,000 pounds at launch Flies at mach 5

How effective was the Patriot vs the Scud? In the initial trials, extremely In 'economy' mode, somewhat less effective  The PATRIOT missiles were skewed towards the front of the Scud  The idea was to disable / detonate the warhead  Worked as planned, but that left several tons of falling rocket When deployed to Israel, the 'economy' mode was less helpful as Israel is a densely populated area. The worst failure occurred Feb 25, 1991 – 28 dead, 97 wounded.

So what went wrong that day? A software error in the Engagement Control System caused the PATRIOT guarding the area to lose track Without a good target track, the PATRIOT missiles cannot engage So it never fired at the Scud

Normal operation (this is all from the GAO report)

The range gate error

What happened that day

A Perfect Storm of circumstances 1.The PATRIOT system's software had a flaw 2.Our Army never found the flaw due to how they used the system  Used as a point defense system against the Soviet Union mostly  Moved around constantly for security reasons  Pretty reliable, but if down, it took a long time to repair 3.I had just finished the TMU project at Raytheon, and the upgraded units were in the field – both in Saudi Arabia and Israel.

PATRIOT TMU Program Meant to upgrade the PATRIOT transmitter units with new control logic Simpler, fewer parts to replace Faster to repair More self-test information available Better health monitoring Replaced 63 circuit cards with 13 cards (including a microprocessor) Program length was 5+ years from contract start to first units leaving factory

PATRIOT TMU Program 63 circuit cards AND cards OR cards Inverter cards Digital counter cards All circuits wired on a backplane, using individual wires, like this:

The Storm continues 4.The PATRIOT systems were being used in fixed positions, run 24 hours a day 5.With the TMU improvements I made, the system was both more reliable (it could spot trouble sooner) and much quicker to repair 6.The Israel Army found the flaw in PATRIOT when running for as little as 8 hours 7.They alerted our Army, which issued a vague warning that didn't prompt anyone to action

The Storm breaks The Iraqi launched a Scud missile at Dhahran, in Saudi Arabia The Scud functions perfectly The PATRIOT battery guarding the city was running too long, and the flaw prevented the missile from being tracked. The automatic systems never fired There was no time for the operators to do anything The Scud hit the barracks, killing and wounding 125 people

And yet it could have been prevented Raytheon worked on a software fix to the flaw for 2 weeks after it was found – the two weeks prior to the attack Distributed patches for the software to all PATRIOT units in the theater The patches arrived on Feb 26 th One day after the barracks was destroyed.

Nothing like that can happen to me, right? No matter what we're working on, there is almost always some potential for disaster, especially with software and hardware for the military (also CIA, NSA, etc.), transportation, and medicine (and many others). Sometimes it's not even doing your job wrong, but doing it right, that can lead to disaster. How will YOU handle it?
