Melissa Pemberton diving towards the earth at break neck speed,lifting back up at the last moment.This is pulling some serious G's.I have nothing but admiration for these daring pilots after spending 30 minutes or so up in the air with Ross Granley doing some very simple maneuvers.The G force I felt left me light headed for a few days,so how they do this and still have the presense to control these speeding machines I have no idea.
