Final answer:
The Flying W logo's designer is not identified, but related to the Wright Brothers and their Wright Company formed in 1909. Paul Rand was a prominent designer of iconic logos in the 1950s and 1960s but wasn't associated with a Flying W logo.
Step-by-step explanation:
The designer of the iconic Flying W logo is not explicitly mentioned in the details provided or well-documented in the public domain. However, if the question refers to the logo related to the Wright brothers and their aviation company, it's important to note that the brothers, Orville and Wilbur Wright, formed the Wright Company in 1909, after their success in aviation. They are known for developing the Wright Flyer between 1903 and 1908, rather than for a specific logo design typically associated with companies. For modern iconic logos designed in the 1950s and 1960s, Paul Rand is recognized as a prolific graphic designer having created logos for major corporations, though he isn't associated with designing a Flying W mark.
