If we send a particle at 0.99c then we measure it moving at 0.99c, not moving slow. If you had a clock on those particles and could observer it the clock would seem to be running slow. If you had a space ship that could travel 0.99c and went for a trip when you got back more time would have passed on Earth than on your ship. This is called the Twin Paradox.
DaleS, you are mostly right except one thing. We (outsider) will observe 'the 0.99c particle slow down near horizon of event'. The clock on the ship looks to slow down, means all motions slow down including ship movement when observed from far away.
