Hello Megan,
I am positive the relatives have no clue about what really happend with the Puma, or where exactly was shot down. In fact, they believe the helo was shot down over sea, near Sea Lion Island.
If i match Coventry´s BoI with Broadsword log (Coventry´s log was lost), this is what happened:
Lively (Boungaville) is circled, some 17 miles south of the engagement area.
All others helos lost were accounted for:
A mistery is in place!
Best regards,
Mariano
