It's enough for me that a conspiracy would be completely impossible. It's not just scientists (geologists, meteorologists, biologists, physicists etc.) who'd have to be in on it, but the media, pilots (both military and civilian), ship captains and countless other groups.
Indeed, it's information it'd be impossible to suppress. For example, this forum contains way more than enough people to prove the earth is round: Just get everyone to say whether it's day or night for them and plot it onto the claimed earth model. You'll see that it's day on half the sphere and night on the other no matter how many times you try it. I don't need to try this experiment personally to know that some forum somewhere must have and obviously nothing ever came of it.
And then there's the fact that, as you imply, it is indeed possible for groups as small as one or two people to do the science proving the earth is not flat. For example, place cameras looking into vertical narrow shafts such as wells and observe the angles of the shadows when the sun is high in the sky.
[Edit: Soupspoon's way is even easier, and can indeed be done by one person]
Conspiracies are only plausible if a very tiny group of people are involved. Once it's open to anyone in the world to discover the truth it's not plausible for the truth to be suppressed.
It's odd to me that that isn't the end of it though, and that clearly people are convinced to the extent of parting with hard-earned cash over it.
