I think this "bigger ships" piece of information is way too vague to draw any conclusion or evidence from it. What is the reason to keep back all other relevant information? I mean why hasn't there any more been said about these? Size, type, color, when, where, etc. - They did not lack the time to do so. And FS did not even ask.
"Bigger ships" may be also from the bad side, SSP, etc.
Yes one can speculate around why it might be a strategy to gradually increase and so on. But at the end I do not really understand that. A lack of transparency undermines the trust level of the existing audience and leads to a feeling of beeing somehow excluded or tricked. But they want a bigger audience. They want FS to be their mouthpiece, but keep back the most relevant information. They say they are militarily superior and have nothing to fear. Then they say they can be / have been shot down. And then they appear regularly over remote and isolated military bases without beeing shot down. Reason: the deep state does not want to expose their tech. That all does not add up. They say we'll show up day and night, take out your cameras! I've not seen a single good shot yet. Why don't they come close posing for a good one? Is this to fuel the Mainstream's speculation and dismissal before the real show begins? Why they do not tell that to us then? It would be irrelevant for the success of their strategy. The speculations are there with or without that.
I've seen nothing so far no small, no big (except the very close big grey triangle, a year ago), and I go to smoke outsides every night.
