so my question is.
Dennis Tito has been to space in 2001 becoming the 1st tourist to do so. so if the earth is flat then by extension he must know space travel is a hoax.
so,why is he investing 66 million dollars of his own money into an event he knows is impossible. also how is he going to convince paying private companies, each that are experts in the field they operate in, that he is pulling this of when in fact it will all be a hoax according to FE.
I still feel like you are trying to bait us into arguing about something that hasn't happened yet, unless he's actually started working on the project. As it is, this is a thread about some eccentric old billionaire's crazy flight of fancy. Eccentric old billionaires have crazy flights of fancy all the time.
Honestly, does this guy look entirely sane to you?

He looks like a child who has just been told by his parents that for doing so well at the piano recital he can have McDonald's for dinner tonight.
Now I of course do not believe the Conspiracy is a necessary condition for a flat Earth. So any speculation on my part about why he would do such a thing, assuming he would do such a thing, would be pretty idle. I wouldn't hesitate to suggest in the spirit of the moment that a slumping NASA could be trying to use something like this to revitalize the public's interest in space travel, as we may deduce they have already (unsuccessfully) attempted with Richard Branson's crazy flights of fancy.
I would also add to this wild story I've concocted at your demand in an attempt to refute a thus-far imaginary scenario that as a former rocket scientist, it's entirely possible that Tito was no stranger to the Conspiracy even before he allegedly went into space.
