I really enjoy photos from space... but, I was thinking this thread could use a shift in genre.
I don't know if these are "great" photos but they are some of my favorites.
Some for visual content, some for historical value, some for their glimpse factor (as ... into their lives), and some for their "that's just cool" aspect.
Glimpse:
Madona
Visual:
Dragon Cloud
Historical:
Ira Hayes, John H. Bradly, René Arthur Gagnon (Raised the flag on Iwo Jima, pictured with
the actual flag used held by John Wayne.)
Just Cool:
