I'm finding it hard to understand why no attempt was made to continue with the the offending flight-plan handled by the manual system. For arguments sake, say after a cold restart of the system in case there had been any corruption.
Presumably some sort of fix or all-clear was eventually issued (I assume "continue but handle the offending flight-plan by hand"). I'm having difficulty imaging what type of issue(s) would require 4 hours to find or exclude.
PS I'm in some of the outer circles of confusion shown in the latest New Scientist cartoon.
