Our strategy for Airfield Chase level 9-10 is to fire the Yellow bird head-on into the wooden base of the left tower. Next, fire the White bird over the plane and drop the bomb slightly right of the middle. The explosion should cause the tail to fall on the gas can and clear the right side of the level. All that remains in an arcing shot to reach any remaining cages. The score in the video below is 94,440.
Note! With the v1.3.1 update Rovio flip-flopped level 9-10 and 9-11, hence why the level number in the video below shows “9-11”. The walkthrough is correct though and the leaderboard entries have all been switched to reflect this change.
