But the crew was probably now the only spotted unit in the area.

Actually spotted units get more priority assigned than unspotted. (Planes can "magically" find unspotted units in the immediate target area, something built into the original SSI code).

Me, if I am attacking an area target and I'd like the planes to beat up on several things, then I assign impact points 250-300m apart. Not all on the same hex. Thus the spotting algorithm may find different things to assign for each one.
