Agent dropoff
 

I got this mission to drop off an agent in the vicinity of Fremantle, but when I get to the spot where I'm supposed to drop him off nothing happens. I totally surfaced and went all the way up to the shore to the point of running aground and still nothing happened. Any ideas?

What was your indicated speed? I've found I need to be in 'creeping mode' (1-4 knots) before I get the Agent Insertion screen and the option to launch the boat. I usually try to be within a mile of the insertion point, slow or dead in the water and surfaced before I launch the boat.

I was stopped. I think the problem might have been related to my being pestered by planes around that time and that the area might need to be totally clear.

I have that Mission as well
 

It's one of Mr. Syxx's excellent add-ons. I'm also unable to drop off an agent, even after waiting for nightfall and knocking out two (three?) DD's to get in close. Still enjoyable and challenging, though. Other drop-off missions that came standard with SH4 have featured the world's NOISIEST rubber launch! Sounds like yer boat's been rammed! Don't miss this aspect at all...
