i checked on a local air plane flight,

distance from kuala lumpur to kota kinabalu equal around 1627.284 kilometers.
airasia flight from kuala lumpur to kota kinabalu duration is 2 hours 35/40 minutes

airasia flight from kota kinabalu to kuala lumpur duration is 2 hours 30 minutes.



so a flight from kota kinabalu (east) to kuala lumpur (west) should need less hours, not 2 hours and 30 minutes.

a more straight line would be kuala lumpur to bintulu,

airasia flight from kuala lumpur to bintulu duration is 2 hours / 2 hours 10 minutes.
airasia return flight from bintulu to kuala lumpur is 2 hours 5 minutes.

does earth spins?

Airline flight durations are not affected by the Earth spinning or not. The travel times are different because of the wind direction. The jet stream is a well known phenomenon.

BTW: The wind directions are affected by the Earth spin because of the Coriolis effect. Hah, so I suppose indirectly the flight times are affected by the Earth spin.

kuala lumpur to bintulu


quite near equatorial line,


should flight from bintulu to kl uses drastically less time?
as the plane flies above, kuala lumpur is spinning to bintulu position,

flight from kuala lumpur to bintulu would takes more time, more speed,
as plane flies above, bintulu is spinning away to east from its destination at 1600 km/h

or i understood the globe earth wrongly? revolution.

The air moves and spins with the Earth. It all moves together.

i don't get it revolution,

And the speed at which the pilot decides to fly the airplane, which may be set lower or higher by the pilot or the airline depending on various economic and scheduling factors.

You don't get what?

are we inside a huge container? like inside a car or plane?

if a person lift a toy helicopter in boeing 747 moving 988.13722 Kilometer/Hour
the toy heli will stationary there although the boeing moving fast.

so could it be container inside other container and more container?

It is all relative. If you are on the equator then you are "moving" at ~1000 miles per hour. But you don't feel anything because of two things: 1) the air is also moving with you so ignoring small local wind effects you feel nothing, and 2) the Earth is spinning at a constant speed so there are no acceleration forces acting upon you.

If you were to continuously fly your jet at ~1000 miles per hour in a westerly direction then the Sun would neither rise nor set, ever, because your speed would match the rotation speed of the Earth.

If you stand at the North or South pole during the equinox you would see the Sun go around you always on the horizon. And it would take 24 hours to do one complete circuit. Of course, it is really you and the Earth that are turning and the Sun remains in its place while you watch it.

Hehe, and BTW, it only takes one real proof to debunk all of those 200 deliberately misleading "proofs".

How to convince people of bullshit? Just keep applying more and more bullshit until they forget their own name.

There seems to be no end to the amount of crazy in this world.

Absolutely. Just visit the top poster's website and you will realize there are countless oxymorons in this world!

You can probably delete the "oxy" part and make it more true.

Also that whole site exists only to bring in ad revenue. So it seems that bullshit sells, and sites with real and useful information are doomed to obscurity.

Sigh. The English standards of some I.T. professional are really falling off a cliff:

Adjective: true
Comparative: truer
Superlative: truest

Refer to the following link:
http://www.dictionary.com/browse/true?s=t

Sorry, English is not my first language. I will try to improve.

As a native English speaker, I find "more true" to be spoken and written more often than "truer," even in formal writing.

Yeah I never hear anyone say truer, it even sounds weird when I say it. more true and truest sounds best imo.
