Jamie and 377, Don't forget that Cooper only had between 40 and 60 seconds to troubleshoot and correct any problems that he had during the free fall.

60 seconds from 10K? tumbling? = splat, surely

Oh! But people have fallen out of planes and survived!

Quade, It would take about 40 seconds or less to fall 10,000 feet in a head first position (at 180 MPH or more), about 60 seconds in a stable spread position (at 120+ MPH), and somewhere in between if tumbling.
While people have fallen out of airborne aircraft without parachutes and survived, there have been instances of people being killed from falls out of aircraft that were parked on the ramp.

In dictionary, under "sarcasm", see entry re: previous post.
But please, do tell me more about freefall speeds.

Quade, Let me point out first that all the comments below my name above are your comments.
My desk dictionary defines "sarcasm" as "the use of iorny to mock or convey contempt".
Per our exchanges of a few days ago, my desk dictionary defines "satire" as "the use of humor, iorny, exaggeration, or ridicule to expose and criticize people's stupidity or vices".

Quade, Since you love to take issue with other people's computations, but refuse to show your own, perhaps you would be kind enough to consult your dictionary about the definition of the term "gravity".
Once you understand what that word means, perhaps we can have a meaningful dialogue without ego's getting in the way.

None survived it twice.
Only a couple off the Golden Gate Bridge have survived.
Robert's velocities (different configs) are correct.
Cossey's hard pull by WII standards was a
qualfiied hard pull - it all comes back to his
experience.
But its not just "hard pull". Cossey describes a
two stage pull ... out and up. Could an unskilled
person manage to perform that combined pull.
by accident?
wouldn't need to survive a no pull if he checked the chute before jumping.
why are we just assuming he didn't?
officially it's assumed he had no jump experience because otherwise he wouldn't have jumped?
really?
thats like saying everyone likes Justin Beiber or all white people are neo-nazis.
it's like a catch 22.
he can't be experienced because if he was he wouldn't have, and if he wasn't experienced he died.
and was washed out to sea or, not, or ???
all plausible I guess, but no more plausible than He checked the chute to see how it worked.
so far everyone who claims to be in the know, or has had access to the FBI files more than the rest of us says theres all kinds of things not released but, when asked what that is, it turns out pretty much all of it has been made public?
it can't be both ways. and the public shouldn't be expected to just accept an official story just because so and so says this is how it went.

Hey...I am not a math expert, but there is a 50/50 chance my Dad was D.B. Cooper. He either IS or he ISN'T.
I am not convinced that he is Cooper, just putting the information out there.

It depends... Where you run into trouble is where the ripcord cable is making a 90 degree or greater sharp turn. The cable runs through a flexible housing (conduit) until it exits near the ripcord handle. The housing smooths things out and acts as a bearing surface to allow the cable to follow a curved path without hanging up. Once the cable exits the housing near the handle, sharp turns become far more problematic. The end of the cable housing has a smooth rounded surface (ferrule?) that acts like a pulley so that perpendicular forces can still exert a pulling force on the container closing pins that are swaged onto the cable, but it compromises things if the pull force is off the cable axis.
My rigger made sure that the end of the housing near the handle was not firmly attached at the end (he tacked it down to the harness an inch or so away from the end) so that it could flex to accomodate angled pulls, but I have seen rigs where this was not done. The best handle pull direction is one which is in the same direction as the cable runs inside the housing. The MEs can explain it better than this EE, but I think you get the picture.

I do think with strong but humanly achievable pull force, the Cossey rig could have been opened without any complicated "out and up " sequence , but that's a guess. My point is that any significant difficulty in the initial stages of an attemped pull can set in motion a chain of events that has killed EXPERIENCED jumpers in in DAYLIGHT who had reserves! Sequence is: hard or no pull, jumper panics, grabs something besides a ripcord handle (usually harness webbing) and fights with it all the way to impact. Sounds implausible but it has happened multiple times in the days before AADs were common.

I don't see how the FBI can insist that he didn't secure the briefcase or his shoes to himself in some way.
unless of course someone was there watching which, according to the public evidence isn't possible.
what were essentially left with is a dictated official story that ignores serious holes.
who is to say he didn't feed the canopy our the door first and didn't even need to pull to begin with?
sure it wouldn't have been a pleasant jump but still seems survivable.
far too many assumptions in this official story, only evidence that could prove it is either non-existent or not-public.
considering the age of this case, why with-hold anything at this point?

QuoteCooper may or may not have survived the jump. Clearly if he didn't none of the names that have been put forward were Cooper
Sorry Orange but isn't one of Vickies possible clues that her father was not seen or heard of since 71. This means he MIGHT still be a possible suspect?
