You must have completed all of your primary objectives first.

To trigger the bombing of the plane you don't actually 'designate' the target, unfortunately. UBI forgot to set that action up in the game, AFAIK.

Just get to the VERY top of the scaffolding, next to the big sign and you should hear some dialog and the plane will come in and drop the bomb. It's kind of fun to use your binoculars, look left and try to follow the bomb in (it's very fast). Then it's mission complete!
