200 Proofs that Eric Dubay is a liar and an idiot

"If Earth were really a ball, there would be no reason to use rockets for flying into “outer-space” anyway because simply flying an airplane straight at any altitude for long enough should and would send you off into outer-space. To prevent their airplanes from flying tangent to the ball-Earth, pilots would have to constantly course -correct downwards, or else within just a few hours the average commercial airliner traveling 500mph would find themselves lost in “outer-space”. The fact that this never happens, artificial horizons remain level at pilot’s desired altitudes and do NOT require constant downwards adjustments, proves the Earth is not a ball." Dubay repeats "proof” 15 just more verbosely. < Prev      161-170     Next >

“If the Earth were truly a sphere 25,000 miles in circumference, airplane pilots would have to constantly correct their altitudes downwards so as to not fly straight off into “outer space;” a pilot wishing to simply maintain their altitude at a typical cruising speed of 500 mph, would have to constantly dip their nose downwards and descend 2,777 feet (over half a mile) every minute! Otherwise, without compensation, in one hour’s time the pilot would find themselves 31.5 miles higher than expected.” False fact, incorrect conclusion A plane tends to stay at a given altitude because the upward force (or lift) exerted on its wings is equal to the downward force exerted by gravity.   To pull further away from the earth (the centre) the plane would need to increase the upward force.   Obviously this means that if it does not increase the upward force the plane will remain at the same distance away from the earth. In practice, because of atmospheric variances pilots...
