I have to admit, I missed that one, the first time around. Could it be that I'm not quite as old as you two? ;-) I'm only 29, really I am, I just look like this because I had a rough youth. Now, of you don't like that lie I will tell you a better one next time. Beneath our gnarled wrinkled carcasses we are all 19 :-) Hear Him! |

I read or perhaps misread that rescue chutes might bring you to the ground at about 25 feet per second. This is about as fast as you'd be falling from a bit less than a 10 foot free fall under 1 G. I remember an old physics axiom that states if you were in free fall under 1 G for 10 feet, and you stopped in 1 foot, you'd experience an average of 10 Gs. Your recollection of the physics is correct. The basic equation for uniform accelerations (no drag, no initial vertical speed) is: a*Sa = g*Sg where "a" is the deceleration rate, "Sa" is the deceleration distance, "g" is the acceleration of gravity, and "Sg" is the distance the object fell during free fall. Derivation is left as an exercise for the student. :-) 10 Gs in a sitting position is pretty much in the tolerance range of most of us. Ejection seats in fighters provide about 15 Gs over more than several feet. As to what gee forces are survivable, Wikipedia appears to have a surprisingly decent article on the subject: http://en.wikipedia.org/wiki/G-force |

"a" wrote I was thinking I might get a foot out of the Mooney. The main gear bone is attached to the wing spar bone and that is one piece, going thru the fuselage. You're not sitting on the spar, but almost. The wings are not attached to the cabin, the cabin is built around the wing spar. *********************** Yeah, a Mooney might only get a foot. They are not known for the most "forgiving" landing gear. That aside, I'll take a Mooney as a get there airplane, any day! -- Jim in NC |

And so you think and hope- that you are not easily replaced. g On a slightly different thought, my wife had been previously married, and had left her ex because of some extra-curricular activities on his part. Now, when I screw up on something (fairly large screw-ups) she is quick to remind me, saying, (I got rid of one, already. I can do it again, just as easily) This, with a smile on her face. I think (hope) she is joking on that one, too! g -- Jim in NC Being introduced as "My present husband" keeps one's role in context, doesn't it? Thanks - good points.
