In October 2026, YouTuber Cody Detwiler, who goes by the name WhistlinDiesel online, modified an old FedEx delivery truck by installing a powerful aircraft engine. His goal was to create a vehicle capable of delivering packages in just one minute. The truck, a 2005 model purchased second-hand, had its original engine removed due to failure, leaving a large empty space. Detwiler replaced this with a Viper 11 jet engine, a type commonly found in training planes like the Jet Provost and Macchi MB-326. This engine produces around 2,500 pounds of thrust, making it significantly more powerful than any standard vehicle engine. Detwiler described the project as a "mechanical monster," highlighting its potential to deliver packages in record time. However, he admitted that the truck lacked modern features such as brakes and power steering, which made it difficult to control. During the first test run, the jet-powered truck successfully delivered a package in under a minute. However, the second run was much more unpredictable, with the steering wheel becoming extremely heavy and the truck pulling in unexpected directions. In an unusual incident, a fake rabbit that was placed in the cargo area was accidentally left behind and was sucked into the engine's powerful air intake. The project continued to face technical difficulties. At one point, the jet engine's starter failed at a gas station, leading Detwiler to comment that "there are things on this earth that are not meant to exist." He noted that he had used four starters, each costing $250, totaling $1,000. Despite these mechanical issues, the project did not result in any explosions or injuries. However, the jet-powered truck became more of a spectacle than a practical delivery vehicle, consuming a significant amount of fuel, starters, and mechanical ingenuity. While the project was ultimately more of a demonstration than a functional machine, it captured public attention and showcased the limits of modifying everyday vehicles with aerospace technology. Detwiler's endeavor, though fraught with challenges, highlighted the creative and sometimes reckless pursuit of pushing engineering boundaries.
