More so that this global conspiracy would have to cover every employee ever of NASA, US airlines, private space sector, and all other organizations around the world.
Do you have any evidence to support your outlandish claim?
First, just saying something is outlandish does not make it so. The definition of outlandish is
looking or sounding bizarre or unfamiliar.
"outlandish brightly colored clothes"
What I am saying is far from outlandish. Now, in the literal sense, would they have to cover EVERY employee? Clearly not. In the case of NASA I am sure there are plenty of lower level employees who have no interaction with the higher functions of NASA. Perhaps a janitor or the like.
For the sake of this argument, I am speaking about every employee who would have access to satellite images, astronauts who have been to space, etc.
To that end, the proof is self-evident. There are no NASA employees who have come out in support of the flat earth movement or commercial pilots.
