In this video, we explore the full history of the P.74—from its inception in 1951 to its silent demise after failing to take flight in 1956. Discover the technical challenges, strange design choices, and the forgotten plans for its commercial successor, the P.105. Whether you’re a fan of aviation history, experimental aircraft, or engineering failures, the story of the P.74 is one you won’t want to miss.
