The Japanese used six aircraft carriers, Akagi, Kaga, Sōryū, Hiryū, Shōkaku, and Zuikaku.

So that's how they did it.  And?

Here's the Book of Enoch regarding the sun.

The "Book of Enoch" is apocryphal, sort of a rejected / not approved private revelation of obscure origin. It's not even part of the Hebrew Bible or Tanakh (see wikipedia). For good reasons it's said to be pseudepigraphical (not of Enoch, so the vision is a lie). Claims that Holy Scripture quotes the book are unproven, and aren't provable by principle.

Now, since flat earthers seem to love that book, here what it says about the sun rising and setting (using a different translation calling the "portals" gates [of heaven]):

CHAP. LXXIV. 12. Twelve gates I beheld in heaven, at the extremities of the earth, through which the sun, moon, and stars, and all the works of heaven, proceed at their rising and setting.

CHAP. LXXV. 1. And at the extremities of the earth I beheld twelve gates open for all the winds, from which they proceed and blow over the earth.

CHAP. LXXXI. 5. With respect to the progress of the sun in heaven, it enters and goes out of each gate for thirty days [plus one day per quarter of the year, see LXXXI. 5.]

The twelve gates are sections of 360°/ 12 = 30°, at the extremities of the earth. Hence, rising and setting of sun, moon, and stars are (not apparent only but) real. Sun, moon, and stars ascend from the extremities of the earth and descend down to the extremities of the earth again.

CHAP. XXXII 1. From thence I went on towards the extremities of the earth ; where I saw large beasts different from each other, and birds various in their countenances and forms, as well as with notes of different sounds.
2. To the east of these beasts I perceived the extremities of the earth, where heaven ceased. The gates of heaven stood open, and I beheld the celestial stars come forth. I numbered them as they proceeded out of the gate, and wrote them all down, as they came out one by one according to their number. I wrote down their names altogether, their times and their seasons, as the angel Uriel, who was with me, pointed them out to me.

The hero went towards the extremities of the earth, sees beasts and birds, and sees that heaven ceases, and sees the gates of heaven. He sees the celestial stars come forth from the gates.

Conclusion: Following the book of Enoch, the rising and setting of sun, moon, and stars is real, and not apparent only. The book of Enoch contradicts the flat earthers' model of the trajectories of sun and moon circling at constant height (Lady Blount, Eric Dubay, most online flat earthers, CI flat earthers). It also contradicts the claim that rising and setting are apparent only (explained on CI by an unreal "Perspective Matrix").

So much for the credibility and solid research of CI flat earthers.
