One strategy for Angry Birds Red’s Mighty Feathers level 24-15 is to aim the Red bird below the blue balloon. Before reaching the rope, target the rightmost hovering contraption’s TNT block. The suction container will fall to the ground and should destroy the rightmost structure. Meanwhile, the indestructible blue balloon will destroy the middle contraption. A simple shot into the left TNT will finish any remaining pigs. The score in the video below is 85,420.
