According to modern spacecraft propulsion theory, rockets are launched, to quote M. Williamson, in the "same direction as the earth's rotation, thus saving energy by imparting a velocity of almost 1700 km ... second booster - the apogee kick motor (AKM) ...".
1984 Physics in Technology 15 284-90.
Robert Sungenis of the Bellarmine Theological Forum, however, has commented differently (in a recent e-mail), that:
"As for the supposed boost, the same forces will be present in a rotating universe around a fixed earth as a rotating earth in a fixed universe. All centrifugal, Coriolis and Euler forces will be identical. This has been shown mathematically by Barbour and Bertotti and many others, including Einstein himself. That's why Einstein said there is no difference between the two models".
