The Vincennes incident (disaster)

01/11/2015

To err is human, but to really screw it up takes a team of humans and computers…

How did a state of the art cruiser operated by one of the worlds superpowers end up shooting down an innocent passenger aircraft? To answer that question (at least in part) here’s a case study that’s part of the system safety course I teach that looks at some of the casual factors in the incident.

In the immediate aftermath of this disaster there was a lot of reflection, and work done, on how humans and complex systems interact. However one question that has so far gone unasked is simply this. What if the crew of the USS Vincennes had just used the combat system as it was intended? What would have happened if they’d implemented a doctrinal ruleset that reflected the rules of engagement that they were operating under and simply let the system do its job? After all it was not the software that confused altitude with range on the display, or misused the IFF system, or was confused by track IDs being recycled… no, that was the crew.
