Wings of Justice - S1.E17

Treize manages to knock one plane down which activates the emergency beacon. Lillia and Treize stall long enough to allow Allison to rescue them by shooting down the remaining three planes. The only thing left to do is land the plane, but Treize does not have much confidence that he can do it. In the end, he makes a successful landing, but hits the bedrock 100 meters from the shore, and the seaplane is sinking.
