Every piloted spacecraft in history. My first rough version of this, thought I'd throw it out for your constructive criticism. My main sources were Wikipedia and spacefacts.de
, but there were several more, and I wish I'd kept track of them properly.
It's surprisingly hard to find pictures of some spacecraft, especially the early Soviet stuff (the sole photo I found of Soyuz T-14, hidden behind a crowd, was especially silly). For others, there are too many pictures to choose from, so I had to make up some arbitrary rules to guide my selection.
My rules were these:
1. Space is above 100km, as commonly accepted.
2. It's got to operate as a whole vehicle on its own, not a module of a larger vehicle.
3. There has to be someone aboard it, operating some sort of controls.
4. They are arranged in forward chronological order of the first moment they had crew aboard in space (so a station launched empty is always listed after the vessel that delivered its first crew).
5. External shots always trump interiors.
6. Crew modules are generally more interesting than launchers or other stages, but everything attached at the moment of the picture must be included as a whole.
7. Space shots trump air shots, which trump outdoors ground shots, which trump indoors ground shots.
8. Shots during space travel trump shots after space travel, which trump shots before space travel.
