179) “If the Earth were constantly spinning Eastwards 1000mph then airplane flight durations going Eastwards vs. Westwards should be significantly different. If the average commercial airliner travels 500mph, it follows that Westbound equatorial flights should reach their destination at approximately thrice the speed as their Eastbound return flights. In reality, however, the differences in East/Westbound flight durations usually amount to a matter of minutes, and nothing near what would occur on a 1000mph spinning ball Earth.”
Oh dear, we are back to this again. Mr Dubay doesn't believe that the atmosphere turns too, and doesn't understand what that implies.
I won't repeat the points covered before in claims 20, 21 and 22, claim 25, claim 27 and at tedious length at other points.
By the way, remember the coriolis effect - you know, the one whose effect on storms proves that the earth is a globe - does affect the routes aircraft have to take. this is well known to all flight navigators, and is yet more evidence for the spherical earth.
