I've done 3 tandems (2 at Skydive Chicago) and the other at Mile Hi Skydiving in Longmont,CO.."they" have both said that you shouldn't feel the acceleration of the freefall. ie: plane is at 100 mph, and ff at 120 mph...I Feel the acceleration, as if I'm being sucked into a tunnel. I'm now in the AFF program and my coach said it's probably vertigo. Anyone else experience this and is there anything I can do to reduce the sensation? or "just deal with it?".... Thanks! _________________________________________
