Wikipedia indicates that the USS Vincennes misidentified Iran Air Flight 655:

Crucially, Vincennes misidentified an Iran Air Airbus A300 civilian airliner, Iran Air Flight 655, as an attacking F-14 Tomcat fighter aircraft. The Iran Air Flight 655 was climbing at the time, and her IFF transponder was on the Mode III civilian code rather than on the purely military Mode II, as recorded by Vincennes's own shipboard Aegis Combat System. Vincennes fired two radar-guided missiles and shot down the Iranian civilian airliner over Iranian airspace in the Strait of Hormuz, killing all 290 passengers and crew on board.

Based on the narrative (and any other supportable information) does the root cause of misidentification comprise:

• Failure to follow procedure (Military / Civilian IFF, etc.)?
• Equipment Failure?
• Human factors (Fatigue)?

The questions are posed because this is the first of at least two Iranian-originating civilian flights that are misidentified by military personnel: I am wondering if there is a pattern, that can produce a lesson-learned (when the final report is published).
