  In August of 2012 the Voyager 1 space probe entered a distinctly new region
of space characterized by a virtual absence of heliospheric energetic charged
particles and magnetic fluctuations, dubbed a "magnetic highway". Prior to
their disappearance, the particle distributions strongly peaked at a 90$^\circ$
pitch angle implying a faster particle escape along the magnetic field lines.
We investigate the process of particle crossing from the heliosheath region
into the "magnetic highway" region using a kinetic approach resolving scales of
the particle's cyclotron radius and smaller. We show that a "loss-cone" type
distribution naturally arises as the orbiting particles enter a region of space
with an extremely low pitch-angle scattering rate.
