Stock campaign, mission 9, as MH-60. Help?

[artao]

So, as the title, I'm playing the MH-60 in the campaign mission 9, South Korea. Supposed to rescue a bunch of personnel from several sites.
The mission brief says that:
a) There'll be heli-pads where I'm supposed to pick people up
b) They'll turn radar on to "track me" and (moreso) for me to figure out wher they are

So I got to my first point, in Seoul, and I'm pretty sure I found my first pick-up point (there's some weird sign half-buried in the ground at that spot, where the ESM picked up a land radar) but I cannot for the life of me figure out how to pick up the people.
I tried landing (by setting my alt. to zero), and that just crashed my chopper. I tried hovering very low, but nothing happened.
Is this even completeable as the MH-60?
I'm quite confused here.

EDIT: note ... i do not get a "Land On" option on my EW contact, which is my only indication of where I'm supposed to go. Also, my EW contacts are not updating. I even went to 2000 ft, thinking they were being masked by hills, but still nothing.
