How do I make an init wait

[Eagle7421 10]

I am trying to make a plane delete itself after a 15 second flyover at the start of the mission using

{deleteVehicle _x} forEach crew av; deleteVehicle av;

Where av is the plane name.

How would I make it wait to do this?

put that in a trigger set to condition true and min,mid,max of 15

Thank you, I knew there had to be a simple answer.
