Birmingham - it was the same unit a few days earlier but that doesn't mean it was the same crew.
it seems reasonably clear that the aircraft went into the water rather than the rock since Dara survived the crash, suggesting an impact that allowed her to escape but caused bad enough injuries for her not to survive subsequently. The other crew members may still be in the wreckage having been incapacitated by the impact. If they had hit land, there would be a lot of wreckage available and no survivors.
Loquatious - not unusual t get tha call out early so it doesn't distract from the letdown process.
