Freddy Jackson
Imagine having a squadron member die in an accident and gathering to take a picture to commemorate him. All your buddies sit down to take a picture, and when it is developed, you find your lost friend standing amongst you. As if nothing had happened to him.
This is the real story of the Freddy Jackson picture. You can see him standing in the background as if nothing had happened to him. It is nice to know that he attended his own memorial. Probably to check on his partners for one last time.
