This mission is way tooooo long for a game that doesn't have a save option.
I made too many things like landing on bridges, cas supports, chasing cars, landing on a frigate etc. And during last take off (probably) from the bridge to pick up my gunner, I hit a tree and died. Nobody can make me play this whole thing again. I will skip this mission and most likely I will not touch Huey for a month.
Also In a campaign that contains so many triggers and missions like this, it is not a good idea to disable the labels and map views.
