Friend of mine jumped thro cloud layers when exact position was unknown but likely over wooded terrain. 3 jumped two stayed and landed with the plane. My friend broke his leg landing other 2 were ok but were lucky.
My thoughts unless plane is on fire or you are absolutely certain of the terrain your are landing on best not to leave the plane. his comment to me after getting out of hospital as I exited knew It was stupid.
All are jumpmasters the 2 most experienced jumpers stayed in the plane.
