@issue - The Online Journal of Business and Design just posted a challenge to their readers. Can you name the airline, just by looking at the tail logo? Airlines put their logos on the highest part of the plane, and they do this so that the logo is the first and last thing you see. Some of these are so iconic that it will be easy for you to name the company. Many of them incorporate the colors of the the flag of the country where the airline is based.
Were you able to name at least half? If so, you know your logos! Or you spend way to much time in airports.
