Rockets and the Spinning Globe

       ORDER MY NEW BOOK HERE

NASA says that rockets are launched eastward with the spin of the earth in order for the rocket to get a boost from the spin.  In other words, they say that the spin of the earth gives the launched vehicle greater momentum and thrust into space.    This allows the rocket to save fuel, they say.  You can see the NASA explanation at this link.

Then why would that not apply to jets and planes?  NASA says the spin affects the velocity and momentum of the rocket as it flies through the atmosphere and into space.  Therefore the spin should have the same affect with planes and jets as they take off. 

For example, if a plane takes off at the equator from east to west, the spin of the earth being against the take off, the plane would have the opposite experience.  The plane would have an earth spinning 1000 MPH (approx.) against it.  That would mean that the plane that takes off at 250 mph would have a net speed of 1250 mph at take-off.  Then, when it reaches cruising speed at say 500 mph, it’s speed would be a net 1500 mph over the surface of the earth.   This means that a plane traveling from east to west, against the spin, would be able to travel 3000 miles in 2 hours (New York to Los Angeles). 

If it travels the opposite direction at a maximum speed of 500 mph, it would not reach New York (pretending New York and LA are on the equator) until the earth rotated one full rotation and New York actually came from behind the plane below on it’s axis.   The speed of the rotating earth would be twice that of the plane.

NASA can’t have it’s physics work two different ways.

Either the spin of the earth is negative with regard to launched and flying vehicles or it is positive.  If it affects the launch of the rocket then it must also affect the launch and flight of planes and jets as they travel the skies. 

The problem is that a plane that leaves St. Louis for Kansas City will arrive the same time as a plane traveling from Kansas City to St. Louis if they fly at the same speed.  That is not possible, according to NASA, on a spinning globe earth.   But it is on a Biblical earth.
