"20 Hrs., 40 Min.: Our Flight in the Friendship" is the title of a book written by pioneering aviator Amelia Earhart. It was first published in 1928, but has continued to be reprinted in periodic new editions nearly 80 years later.

In this book, Earhart writes about her experiences as a passenger in the "Friendship", which made her the first woman to cross the Atlantic Ocean by air in 1928 (she later accomplished the feat in a solo flight). Earhart combines actual log entries made during the flight with recollections of her childhood and how she first became interested in aviation.

This was the first of two books Earhart would write in her lifetime; the other being 1932's "The Fun of It". A third book credited to her, "Last Flight", was published posthumously and consisted of diary entries from her ill-fated 1937 flight around the world.

"National Geographic" named "20 Hrs., 40 Min." one of the "100 greatest adventure books of all time" and republished the work in 2003 under its National Geographic Adventure Classics imprint.
