On April 13, 1970, an oxygen tank exploded on the Apollo 13 service module, which was on its way to the moon. The explosion blew the cover off the craft, stirred its innards a bit, bled away all the reserve oxygen and most of the power, and nearly kept the astronauts from returning to Earth alive.
On April 13, 2004, I took apart the undamaged Apollo service module from LEGO set 7468-1 (Saturn V Moon Mission), and rebuilt it in the exploded state, based on NASA photos such as the one printed in that set's instruction booklet.
On April 13, 2005, I finally got these photos online.
This model is dedicated, of course, to the men who survived the experience.
Here's another view of my model, showing the details better.
Quoting Thomas Le Stum
Very nice, but the original photo has been take from the Command Module, which is docked to the Service Module in your creation.
Good catch. Sure enough, the Command Module is just barely visible in my version of the space photo, and shouldn't be. Oops.
(It's included in the clearer side view on purpose...in this configuration the MOC depicts the ship after it stops visibly venting gas but before Command Module separation.)
