Pig Bang 1-7/Space Eagle

Here is the strategy for 100% total destruction with Space Eagle for Pig Bang 1-7 (Angry Birds Space). Note: You must have least one sardine can to play this mode.

Difficulty
Place the Sardine Can between of the two towers is a hard work.

Strategy
Throw Sardine clockwise, doing a double-loop around the planet. Send the Space Eagle when the can approaches the base of the eastern structure. You are more likely to earn the feather by targeting stone instead of wood.
