Who usually conducts crew mission debriefings?

The correct answer is that the Planning section usually conducts crew mission debriefings. This is because the Planning section is responsible for analyzing mission objectives, evaluating outcomes, and collecting feedback to improve future operations. During debriefings, crew members share their experiences, observations, and any challenges faced during the mission. This information is critical for refining strategies, enhancing safety protocols, and ensuring effective resource allocation for future missions.

The Planning section's role in conducting debriefings aligns with their broader responsibilities of developing operational plans based on collected intelligence and insights, making them the most fitting choice for this task.
