This is when I spotted: a horseshoe shape feature, we can see it better on this map.

一个马蹄铁形的地貌，用这张地图可以更清楚地看到它。

Along the outside of the belt are carved designs, and on the front of the curve of the horseshoe shape, cut into the polished stone, is the stylised image of a toad.

腰带外侧雕有图案，前方弯折处有刻了一只光润的蟾蜍。

While the wings, engines, landing gear, and lower fuselage remain the same as on the standard A300, the upper fuselage creates a massive horseshoe shaped structure that is 25 feet (7.7 meters) in diameter.

虽然机翼、发动机、起落架和下部机身与标准 A300 相同，但上部机身形成了一个直径 25 英尺（7.7 米）的巨大马蹄形结构。
