The Flying Dorito
The Flying Dorito was one of the worst projects that the Pentagon agreed to fund in the 1980s. It experienced issues in many fields, including radar systems and its use of composite materials. In 1991 when the Department of Defense found out that each plane was projected to cost $165 million, Dick Cheney canceled the project.

XB 15
Until the Spruce Goose was created, the XB 15 was the largest plane to ever be built in the United States. This plane was so large that it was able to hold secret passageways and sleeping bunks for the crew on-board. Unfortunately, in 1937 nobody was creating engines large enough to support this plane yet, so the plane was unable to travel faster than 200 MPH. This wasn’t worth it as an army plane, so the U.S. Army killed the project. Only one XB was ever built, and it was used as a cargo plane during WWII.
