Skeptic has released a new SP mission for ArmA2 in the BI forums.

Quote Skeptic :
Nothing special - take off from Utes island, destroy single Armor target and land. Feel free to change in any way or form to familiarize yourself with Su25 flight model. You can replace Su25 with any OpFor aircraft for this mission to work. Target can be anything as long as you keep its ID as OBJ1.
