The background and story build-up are great and it was clear a great deal of thought was put into it. I also liked the fact that the GTD Aeneas was one of the ships mentioned in the actual FS2 campaign. However, the mission goes through a full command briefing and five stages of briefing until it gets to the actual mission objectives on stage six. In a longer campaign, the squadron history should be presented at the beginning of the campaign while the mission context should be part of a command briefing. For a single mission, the squadron history is probably not needed.
A nitpick: space fighting is generally assumed to be akin to the navy, so the battle cry should be Hooyah - and with an exclamation point, not a question mark.
The mission itself was very solid. No technical issues that I could find -- goals, directives, messages, and events were all present and working. I also appreciated having Epsilon wing arrive as reinforcement; that was a nice touch in the pattern of the main campaign.
Gameplay was pretty fun. Reminiscent of a main FS2 campaign mission in many respects. It wasn't too terribly difficult, though I couldn't slack off either. It would have been nice to have a bit more variety in fighters - perhaps mix in some Asteroths rather than all those Dragons - but the Dragons, Maras, and Nahemas were enough to make it interesting.
The debriefing worked as expected, and looking at the mission file, stages were provided for a wide range of outcomes, including AWOL.
This mission was more than "Acceptable"; this was at least "Very Good". It was technically sound, with a good story, and most importantly it was fun to play. I would certainly play the full 10-mission campaign.
