So I finally managed to access the rehearsal schedule for 44FOP last night, and now have a dilemma.
I am unavoidably out of the country for a weekend in June which includes 2 reheasals, so according to the information provided, that automatically relegates me to the reserves list... not sure I can justify attending the other 19 reheasals (with associated time away from the family) if I am not even going to be involved on the day.
