I have downloaded the missions but not flown the Swordfish mission yet. However, if it's like the Beaufighter V's Convoy mission, warp to the first waypoint and then just follow that purple arrow on the tactical display and the ships are not far away. If you warp to the first way point and then warp again, you end up back at your starting location.
Haven't seen the purple arrow but maybe I wasn't looking to closely so I will give it another shot tonight. Yes, I think its alot like the Beaufighter mission.
Speaking of the Beaufighter, is there any way to add rockets or torpedos?
As of the Bismark, I have the ship files, is it just not included in the mission plan? If not, can it be added?
