=MAX(IF(mission=A1,departure_date))

which is an array formula, it should be committed with Ctrl-Shift-Enter, not
just Enter.

How can I search the minimum and maximum values of the rows that follow a
specific condition?

e.g.
A mission means having to travel to a set of destinations.
Columns are Mission, Destination, Arrival and Departure.
How can I build a formula that for a specific mission, searches the lowest
arrival date and highest departure date? In that way I will know from
which
day to which day was the mission.

If I could do an array I would do MAX((mission=A1)*(departure_date))

Thank you
