LOL at there being an exact altitude in which the curvature of the earth can be seen.
I haven't claimed there's an exact altitude at which the curvature of the Earth can be seen. Do not put words in my mouth. All I said is that the altitude you've been at was insufficient, as per RE consensus.
And what part did I not read?
Presumably the OP (an argument essentially identical to yours) and the responses to it - i.e. most of the thread.
Actually, RE'ers claim that curvature can be detected at 35,000 feet.
Actually, no.

It's FE'ers that keep raising the altitude requirement.
I've been quite consistent about 60000ft over the past few years (because the RE'er consensus hasn't changed). It's truly saddening that you resort to lying in order to stir an argument up.
