The Flying Dorito
This aircraft might look like something out of an anime or video game, but the Pentagon believed it was a concept worthy enough to throw a lot of money into during the 80s. The radar system on the Flying Dorito was faulty and besides its designers believing that its composite materials were something to brag about, this implementation wasn’t anything novel. Thankfully, the Department of Defense stopped its production in its tracks in 1991 when they discovered that its estimated production cost would be around $165 million, and Dick Cheney gave it the ax.

XB 15
The U.S. Airforce titan was the hugest aircraft within the country prior to the Spruce Goose’s hatching. The XB 15 was so enormous that passengers could easily disappear within it. This aircraft’s size was so overambitious that they couldn’t find engines capable enough to allow it to fly faster than 200 mph. The XB 15 was never developed further and was solely ever employed as a cargo plane during the Second World War.
