I'm trying to think of the last time a product came out and the public and government's response was "That's so amazing, it has to be fraud", but it was legitimate. I'm a little tired, so all I'm drawing is a blank.
(Ironically, this briefly turning into some kind of conspiracy thing was likely fueled in large part because SpaceX couldn't get something else right: their live streaming setup. Even a a year later, the streaming still tended to cut off exactly as the booster was about to land, and resumed with it either in pieces, or safely on the pad. This was a big problem with barge landings in particular - where IIRC the primary explanation was that they just couldn't keep the antenna pointed in the right direction with all the shaking induced by the booster's hoverslam.)
(And yes, I appreciate the irony of getting hung up over live streamed booster landing, as if it was common and expected practice.)
