C&H lost by destroy building

[MaveryQ]

Sorry for may poor english !

I made a C&H (with PVPscriptPackV2_02) map with a control tower like objective.
I would like that if a team A destroy the control tower, the team A lose the game !
So it's the inverse of Destroy !
How can i do that ?

Another question, my planes don't respawn.
What can i do, may i add a command to the unit to specify the respawn

Thanks
