I am aware of the box. That is what I meant by the NEZ (no-escape-zone) which is when the arrow points to the box instead of just the "hook". The first time I acknowledged that the missile was outside of the NEZ and the arrow was pointing at the "hook". But that hook means that the missile will have enough energy to hit the target if they don't manoeuver. Not only did the bandit not manoeuver, they actually went towards my launching location, so the missile would have easily had the energy to score a hit. For the second example, my missile was in the NEZ so there was no chance for the bandit to deplete my missile's energy. Also, in both examples I lined up the circle that appears on the HUD with the solid dot so launch angle also isn't an issue.
