Aigle should've seen your planes coming and hung back from yolo'ing the cap.
Your planes were spotted 26 seconds into your replay and you first spotted the Aigle 35 seconds later. That's a lot of time to reconsider hard yolo'ing the cap and seeing what Happy Ending is waiting inside. "We bomb you long time, $5"
