For a brief moment, you will feel 14 times your normal weight
as the rocket
s underneath your seat fire you out of the plane. Hopefully the canopy
has already blown away. If not, you'll feel a crushing blow
to your skull
, followed by blackness
, and whatever sensation your deity has prepared for you in the afterlife
Assuming you make it out of the plane, you'll think you blacked out. You didn't. Accelerating at 14G will cause your vision to go dark for a moment, giving this illusion. Hopefully, your mask is closed tight, and you won't feel the wind too badly, but it will be a harsh wind. It'll snap you back pretty quickly, especially when your parachute deploys.
Now you can go spend some months in physical therapy and chiropractic care to repair the damage you've just done to your spine. Good luck.
