3rd SU-25 campaign mission problem

[cquail]

Hi,

 

In the 3rd SU-25 campaign mission you are tasked with destroying a bridge. I am able to do this everytime. When the mission is over and I click on next mission the same mission comes up again. This has happened 4 times now. Is there some other mission criteria I am missing? Do both my wingman and myself have to land back at the base successfully?

 

Thanks,

CQ
