The information on the FPL and the response by the ATC Officer is disturbing. Celia's email to her manager appears to pre date the crash, and it indicates that she did not accept the ATS FPL. If so, how did the aircraft end up 1600nm away following an IFR flight. When was the FPL accepted by ATS, and by who, and with what presumed intervention to Celia's legitimate complaints?
This aircraft was never legal to operate this flight under any ICAO Annex 6 Part 1 compliance. This particular part is not recommended practice it happens to be a minimum standard. Para 4.3.6.3 doesn't allow you to be so criminally cavalier as this operation has been, nor does it allow the state to waive the rules if they are ICAO signatories.
These unfortunate passengers and hapless crew have been killed by the actions of the PIC and the dispatcher, and those others that facilitated this dispatch, and the operation of such a reckless program operating outside of the law.
