Celia would not now be hiding in Brazil if it wasnt for that endurance figure on the flight plan. We will never know why it appeared like that or even who actually wrote it in. It must be certain that it was not the captain so was it another crew member trying to send a signal? Having heard of Celia's efforts to get the fpl changed but to no avail,I cant believe that she would not have brought that to the attention of the duty Atco, probably only a room or so above her. If she did the Atco is just as much if not more to blame than Celia, even if he/she also failed to stop the flight ( for reasons already discussed), according to the Bolivians' logic.
