  We develop the Glauber theory description of final-state interaction (FSI) in
quasielastic $A(e,e'p)$ scattering. The important new effect is an interaction
between the two trajectories which enter the calculation of FSI-distorted
one-body density matrix and are connected with incoherent elastic rescatterings
of the struck proton on spectator nucleons. We demonstrate that FSI distortions
of the missing momentum distribution are large over the whole range of missing
momenta. Important finding is that incoherent elastic rescatterings of the
ejected proton lead to a strong quantum mechanical distortions of both the
longitudinal and transverse missing momentum distributions. It is shown that
allowance for finite longitudinal size of the interaction region for
proton-nucleon collision neglected in the standard Glauber model drastically
affects the theoretical predictions at high longitudinal missing momentum. We
also find very large corrections to the missing momentum distribution
calculated within the local-density approximation.
