Unlucky not to get the nod at the first attempt. Weakly recommended means "Branch quotas almost filled, and lets see if someone better comes along in the next couple of boards"
You do still stand a chance but my feeling at this time of year would be think about trying again next year when you will have this experience to build upon and also that the board can see that you are serious about you desire to join. Tip, New financial year starts in April which just happens to be when the RAF decides how many people and in which branches it needs.
EG Decides in April that it needs 100 pilots in the comming year so there will be 100 slots avail from Apr but obviously very few by the end of the year.
