Picard may well have claimed to have seen a Flat Earth, but
He was looking through vintage spectacles
He was peering through thick porthole glass of small diameter, even smaller than today's aircraft windows and
Someone has suggested his craft was leaking, so he have been suffering oxygen deprivation and mild hallucination
So, how reliable?
Piccard knew what he was looking through.
He did not make just one flight. His craft was not leaking all the freaking time.
At the altitude they achieved, you'd need a wide field of view to see the curvature of the Earth.
Yet the claim by Piccard is he saw it as flat with concave(curved up) lip...
Their field of view was limited. Further, their flight occurred over land, which would have influenced what they saw.
Funny! Have you ever taken to task any RE-tard claiming to see curvature from a commercial jet?
Beyond the physical, he is also credited as being the first human to see the curve of the Earth and referred to the Earth as a globe in his writings. This is huge case of confirmation bias. Take one sentence and ignore everything he wrote and studied. (he was a scientist and not a flat Earther)
So, you spend your entire first paragraph arguing against his capability to adequately see what he was looking at and then close your post, virtually AFFIRMING BY GOD he was able to see the curve...
WTH is the matter with you?
I was addressing the limitations of the craft in the first couple of sentences and then pointing out that the very guy you're trying to claim thought the Earth was flat, in fact, knew it was a globe. Wipe the spittle from your mouth and go back and re-read what I wrote.
No, you argued against the validity of all of his observations, and then tried to claim those same observations earned him the title of the first person to ever observe the "curve," of Globe Earth...
So which side you on...You cannot have it both ways.
By the way, please pony up a valid source indicating Piccard ever claimed to see the "curve of the Earth."
BTW, referring to logical, educated people as RE-tards pretty much shows you're have the mental age of a child. Do you laugh when you type it? "hehehe, I said RE-tard." Grow up.
I see no evidence of logic or education in a post or in a source, I am going to call it like I see it.
If that offends you, so be it.
So, the question remains...You ever corrected a Re-tard for claiming to see the curvature of the Earth from a commercial plane?
