  The Alpha Magnetic Spectrometer (AMS) is a detector designed to search for
antimatter in the cosmic rays. The physics results from the test flight in June
1998 are analyzed and published. This paper reviews the results in the five
published papers of the AMS collaboration, updates the current understanding of
two puzzles, albedo $e^+/e^-$ and albedo $^3$He, and disscusses the influence
of albedo particles.
