The current 50-star flag of The United States of America
This is the flag that was planted on the moon during the Apollo missions, and the flag that survived the sneak attacks on America on September 11, 2001.

The flag under which I was born, served as the offical ensign of the U.S. for 47 years, one less than the current flag. This was the 48 star flag which came into existence in 1912 following the admission of Arizona and New Mexico to the national constellation. This is the banner under which our soldiers fought in both World Wars and the Korean War. It is the flag that was raised at Iwo Jima. It replaced the flag of 1908, the 46-star flag that represented the admission of my home state of Oklahoma to the USA in 1907.
With the stars arranged in even rows, one under the other, the 48-star flag is easy to spot in pictures and movies. An anachronistic mistake sometimes made by filmmakers is the use of the current flag in period movies when there should be the 48-star banner used.

When I was six years old, Congress admitted the territory of Alaska as the 49th state, and a the flag was changed to add the star for our new state. I lived in Houston, Texas at the time, and remember that at that time, Texas dropped from being the largest state in land area to second place. This was a short-lived design, as a year later, Hawaii would be admitted to bring the total number of states to the current 50.
