We estimate the longest possible time from mission start to TOT for all flights in a package and use that to set the TOT (plus any delay used to stagger flights). This both cuts down on loiter time for shorter flights and ensures that long flights will make it to the target in time. This is also used to compute the start time for the AI, so the explicit delay option is no longer needed.
