By Garth Calitz In the long history of experimental aviation, few aircraft have looked as unconventional or as quietly influential as NASA’s AD-1. With its single pivoting wing mounted diagonally across the fuselage, the AD-1 appeared less like a conventional aeroplane and more like a designer’s sketch brought to life. Yet behind its unusual appearance lay a serious aerodynamic concept that aimed to address one of aviation’s most enduring challenges: how to reduce drag and im

By Rob Russell In the early 1970s, following the successful launch of the first wide-body airliner, the 747, Boeing began looking to further develop its narrow-body 727. Designed for short and medium-length routes, the trijet was the best-selling jetliner of the 1960s and a mainstay of US and European airlines. Studies focused on improving the 189-seat 727-200, the most successful variant. Two approaches were considered: a stretched 727 (to be designated 727-300), or an all-n

By Rob Russell It was ugly to start with and got uglier as the British tried to put more stuff onto it. It reminded people of the Australian platypus with its monstrous, ugly nose! It was in the tradition of all British aircraft - build a good aircraft and then add on and on - remember the Canberra, with the cockpit on the side, almost as an afterthought and the original Hs25 series, where it looked like the cockpits were stuck on the front? The British Aerospace Nimrod AEW3 

By Garth Calitz The Blohm & Voss BV 141 stands out in aviation history as one of the most unusual and radical aircraft designs ever flown. Developed in Germany in the late 1930s, its quirky, asymmetrical structure was born from a particular operational need: maximum observational visibility. However, it ended up being one of the Luftwaffe’s most fascinating engineering experiments. Despite strong performance in flight tests, it never achieved full-scale production, overshadow
