Complex Missions: When does a mission end and the next mission begin?

You were originally scheduled to fly a platelet mission from your home base Deer Valley (KDVT) to Flagstaff (KFLG) and back to KDVT.  That morning, you agree to also take blood products on an unscheduled mission to Prescott (KPRC) and Cottonwood (P52).

You then call the Mission Coordinator so that he/she can add the Unscheduled Mission to your schedule.

1st mission DVT – PRC – P52 ends when the blood product for that unscheduled mission has been delivered in Cottonwood.

2nd mission P52 – FLG – DVT ends when you return home to DVT. 

Report the mission as you flew it – as two missions.
