Chapter on navigation, Dead Reckoning (no GPS, only calculated flight path)

No mention is made of the supposed rotation of a globe earth.

If someone were to fly from North Dakota to Texas (North to South), the supposed rotational velocity of the earth beneath the plane would go from 872mph to 901mph (rotating to the East on the alleged globe).

The maximum cruising speed of a Cessna 172 Skyhawk is 142mph. Based on the numbers it would be unable to maintain a course that both keeps it over the USA and progresses to its destination in Texas.

The Pacific Ocean is about 1000 miles West of North Dakota. The net velocity of the planes speed minus the earth's rotation (giving actual speed over the ground) would put the Cessna over the Pacific Ocean in around 2 hours.

Yet people fly slow propeller aircraft over the USA all the time, and no one ends up over the Pacific because they flew too slow to keep up with the supposed rotation. None of them will have needed to take into account the Earth's rotation in their journey planning.

Additionally look at the Red Bull High Altitude jump, proof of both a flat and non-rotating earth



He landed 44 miles EAST! of where he took off, when he should have been out over the Pacific on the rotating globe. Additionally the internal view shows the horizon just as level as when he took off, when on a globe it should have dropped far beneath that.
