Danger Above 8-15

Theme 8-15 is the final level of Danger Above.

Strategy
Fire the first Yellow bird into the column of TNT at the far right. The resulting damage varies a bit, but the goal is to have a clear shot to the TNT in the bottom-right. If possible, execute this shot with the next Yellow bird. Fire the Boomerang bird head-on into the top-left structure, detonating the TNT within. Of course, higher scores result if you trigger the plethora of TNT in the bottom-left, but that is not an easy task.
