Some other things I found that grabbed my attention. The whole Trieste program completely fascinates me. The Navy Museum onboard the Navy Yard in DC has the better Trieste display overall (duh - they have the vessel), but what the Mariner's Museum did better was the display. I learned some new things about the vessel and the mission.
Ship emblems are also really cool nautical fare. They are not as colorful today as they used to be.
