Australian Plate south, is now being torn apart along the transform boundary marked by the Alpine Fault. South of New Zealand the boundary becomes a transitional transform-convergent boundary, the Macquarie Fault Zone, where the Australian Plate is beginning to subduct under the Pacific Plate along the Puysegur Trench. Extending southwest of this trench is the Macquarie Ridge. The southerly side is a divergent boundary with the Antarctic Plate called the Southeast Indian Ridge (SEIR). The subducting boundary through Indonesia is not parallel to the biogeographical Wallace line that separates the indigenous fauna of Asia from that of Australasia. The eastern islands of
Dwane Wallace After the war, Wallace quickly developed an all-metal replacement of the C-34—the Cessna 190 / Cessna 195, a speedy 6-seat, single-engine, executive aircraft, powered by a large, traditional radial engine. Wallace then guided Cessna away from the pioneering un-braced "cantilever"-wing design concepts of Clyde Cessna, towards more conservative-and-traditional, "strut-braced," high wings—producing the world's most successful line of single-engine light aircraft, ranging through numerous variants from the Cessna 120/Cessna 140 to the Cessna 207—despite the industry's move towards cantilever wings. The 120/140 also was the beginning of Cessna's conversion to smaller-cabin aircraft with streamlined, flat, horizontal-cylinder engines. The 120/140's distinguishing feature,
