When someone thinks of the word “aircraft,” they probably think of a boring commercial flight to a much cooler destination. However, the aircrafts on this list will prove that idea wrong, as they are all extraordinary. Whether it’s their speed, flight capabilities, or architecture that makes them stand out, these are all groundbreaking pieces of machinery.
And staggeringly expensive, too. For example, did you know that the Lockheed Martin P-791 cost $40 million to build? All of the manufacturers on this list, no matter if they were contracting with governments or building these planes privately, shelled out big bucks to create some of the most interesting aircraft of all time.
