If you’ve ever dreamed you could fly, you already know exactly how it feels. The $2,950 per seat flights create microgravity environments by swooping along a trajectory that looks like the biggest roller coaster in the galaxy.

Each modified Boeing 727-200 cargo jet climbs from around 25,000 to 39,000 feet, and each time it reaches the peak of that invisible arc, varying levels of weightlessness occur inside the craft, from “Martian” levels at a third of Earth gravity, to “moon” levels at one-sixth of Earth gravity, to absolute zero gravity.



On the ground before liftoff, all 27 passengers on my flight were split into groups of three. My team’s coach warned each of us to sit as still as possible during the heavy-gravity “valleys” along that roller-coaster trajectory — keep your head aligned with your spine we were told, don’t move your head, choose a single point in front of you and stay focused on it. Rapid eye movements create vertigo, and vertigo generally leads to vomit.



Some of my flight-mates took anti-nausea meds like the scopolamine-Dexedrine cocktail popular with NASA flyers. Those taking “scopedex” time their hits like deadheads dropping acid before a show — “Should I take it now? I want it to kick in before takeoff time so I’m good to go when the parabolas start.”



Others like me just crossed fingers and crammed chewing gum, ginger candy, crackers or Altoids into flight-suit pockets.
