+# Task ID: 7
+# Title: Plane Model & Collision Detection Logic
+# Status: pending
+# Dependencies: 1, 6
+# Priority: high
+# Description: Implement the plane data structure (head, wings, body, tail) and the logic for checking placement legality, including boundary checks, no overlap, and completeness. This logic will be shared between client-side UI feedback and server-side validation.
+# Details:
+Define a plane object with its shape (array of relative coordinates from head), orientation, and position. Implement a `checkPlacementLegality(board, plane)` function that verifies all constraints: 10x10 boundary, no overlap with other planes, and all plane parts are within bounds. This logic should be robust and reusable.
+
+# Test Strategy:
+Write comprehensive unit tests for `checkPlacementLegality` covering valid placements, invalid placements (out of bounds, overlapping, incomplete), and different plane orientations. Test performance of the algorithm with multiple planes.
