Dear Jack Martinez,
Jin and Jenna are really happy to let you know that their daughter has passed from the Air Academy. We shall therefore be hosting a party on Saturday, June 25th starting at 6 p.m in the Green Officer Club’s room.
Jenna has achieved a lot of medals and similar prizes during the training period. She begins her duty next month at Cranfield base.”
