The other day I saw this amazing 'thing' fly past. But the really odd bit is that this person was neither gaining height nor decending... I am not sure exactly what is going o. This person actually carried on along the ridge line for alteast a mile, then turned around and 'flew?' right by me again just over the other ridge line and was gone.

Exactly what is this ? And how does somone using a 'chute stay at a near constant 10 - 12 feet off the ground height ? With no artificial propulsion ( since there was zero sound ).

For those of you who were not there, a picture to illustrate exactly what was going on:
