Danger Above 6-5

Theme 6-5 is the fifth level in Danger Above, and the very first level containing the Boomerang Bird.

Strategy
Launch the first Boomerang upwards. With precise timing, activate the boomerang mode to hit the middle layer of wood. If done right, the Boomerang Bird should kill all the pigs in the cockpit while the wood falls on the rest of the pigs, finishing them off.
