What I’m getting at is:  if jumping out of airplanes is easy and if Cooper is experienced, then why ask for a reserve?
 

One could label some things Cooper did as disguise:
1) sunglasses
2) smoking
3) saying "front" and "back" chutes like a whuffo.
4) Wearing a suit.
5) timing things for a night jump
6) timing things for a thanksgiving jump?

If he had clearly announced what he wanted and where to get them, that would have been a pretty strong tipoff he was experienced.

Look at it this way: only dumb whuffo FBI would not see thru all the obvious attempts at disguise.

An expert doesn't need much to jump the 727. Making himself look inexperienced takes advantage of his experience, to create confusion for his pursuers.

I mean, he picked the night jump. He picked the time he knew he'd be jumping at ...evening.

Now things that really did matter, he gave exact instructions on
1) flaps
2) speed
3) altitude

so he betrayed some knowledge there, because it was critical to his success. The other stuff wasn't critical. (in terms of how authorities responded)

That sounds like good planning. He knew he could handle a night jump, but his pursuers would have a hard time finding him at night.

Your posts are awesome and if you had a book I'd buy it and I'm glad you're back on the forum but you're not even close to being right here

"not even close to being right here"

WELL! at least we've settled something. Well done! Next issue!

Aren't all db cooper posts "weak"

there's no such thing as "non-weak" !!

touche

and now I'm a party to the continued hijacking of this topic #hypocracy

either way.. go on the podcast and it all evens out

Just noticed that TK detected a lot of brass on the tie, but excluded it because he couldn't rule out contamination without more work.
But maybe the brass was not contamination? Wondering if it might support "refrigeration" shop more.

Finding lots of brass may be as important as finding Ti.

"Anecdotal, many particles of brass were also found on the sticky stubs and in the vacuum filters used to collect the particles. They are not included in this analysis because brass screw plugs were used to seal the sample filters. In order to rule out contamination, micro-x-ray fluorescence must be used to determine the exact type of brass for both the plugs and the particles, but these Fig. 6  Sprial aluminum chip. One of two found on the tie. (Length = 1.6mm)particles have yet to be analyzed."

Also: the size of the aluminum spiral chip was only 1/16" (two)
I wonder if the small size points away from a lathe or drill (TK's suggestion)
A controlled lathe/drill would produce longer spirals of aluminum?
1/16" is pretty small.

None of this is about the Cooper Vortex podcast.

I read your previous response to this inquiry from Chaucer

Your bad faith response was something to the effect of these things could be technically discussed on a podcast. I suspect that is why you were compelled to respond to my question.

By your rationale, anything could be discussed on a podcast thus the Cooper Vortex podcast thread can going forward serve as a slush pile for whatever which is better than you saying "oh yeah my bad" which would apparently be too much.

You have the valid option to just shoot me down as a new poster and then wonder why more people don't get into this case. Or the forum can be reasonable so people can actually follow it.

Your posts are awesome and if you had a book I'd buy it and I'm glad you're back on the forum but you're not even close to being right here

So, - and this is pure speculation - is Cooper's use of a reserve in addition of a bailout chute indicative of a novice jumper? If skydiving is so easy that all you have to do is "pull the ripcord", then why ask for a reserve necessary? Moreover, why is a reserve chute necessary for an experienced jumper if jumping out of the back of a jetliner is easier than parallel parking?:

Also, since bailout chutes like the one Cooper chose aren't used with reserves, then isn't it possible that a reserve chute on his midsection, along with a bag of money enough to prevent his right hand from reaching the ripcord?


The fact that Cooper used the bailout rig is primarily indicative of that's what they gave him. He asked for 'two back and two front' parachutes. That sounds to me like he was asking for two complete rigs, sport mains and the reserves that go with them. Instead of sport mains, they gave him bailout rigs. Bailout rigs do not use additional reserves because they ARE reserves. The design of the canopy is for opening reliability rather than the flight performance a sport main might have. Unlike sport mains, they are required to be packed by a licensed FAA rigger, and at regular intervals whether they are used or not. The theory in an aviation situation that might involve parachutes is that you want to have a parachute that you do not intend to use. Aerobatic pilots or military aircrew take bailout rigs because their type of flying might require them to bail out. They don't intend to, and in effect their airplane is their main. A sport jumper intends to jump and use his main, so he takes a reserve in case it malfunctions. Mains might have design parameters to increase their flight performance that might increase the possibility of malfunction. I have heard the analogy that a skydiver wears a reserve for the same reason a driver wears a seatbelt. I prefer to compare it to a spare tire. I tell my students not to regard a malfunction as a near death experience, but more like getting a flat tire on your car. Swap it out and get on with your day.
I thought they gave him a bailout rig (NB-8) and a sport chute. Plus the two chest reserves? The FBI has used his selection of the NB-8 as evidence that he was inexperienced and chose the inferior chute.

What I’m getting at is:  if jumping out of airplanes is easy and if Cooper is experienced, then why ask for a reserve?

Second, with a bailout rig, a reserve fastened haphazardly to him, plus a bank bag tied haphazardly to him seems indicative to him of someone either really inexperienced or someone utterly reckless. He could have become asymmetrical and ended up in an unrecoverable spin or put himself in a position where the bank bag and reserve interfered with his ability to pull the ripcord.

I’m use brainstorming here, but I’ll bow to your better knowledge on this, Dude.

Mr. Oranchak is a friend of mine, and as I have explained before, he and two other gentlemen solved the Z340 last year. The other Zodiac cipher, the Z408 was solved in 1969.

He will be giving presentations to both the FBI and NSA later this year on how the Z340 was solved. I’ll post it here when I can.

I thought this article was interesting, where the author mused that possibly Zodiac got his idea about how to make the Z340 more complicated than the first cipher, from newspaper article at the time.

i.e

"But what inspired the added complexity and the diagonal shift employed by the Zodiac Killer in his encryption technique on November 8th 1969. The trigger may have been his 408 cipher and the detailed attempt to break it in the Vallejo News Chronicle on August 4th 1969, at a time when the Zodiac Killer would undoubtedly have been scrutinizing the newspapers for progress on his 408 cipher."


The cryptogram fan from San Francisco, a graduate student, made some observations regarding the 408 cipher (shown on the left). While his analysis wasn't wholly accurate, it is this newspaper article that may have bearings on the technique employed by the Zodiac Killer when designing his 340 cipher. On page two of this newspaper article it continued "The pattern beginning to take shape apparently will end up a three-tiered diagonal structure composed of sections, of each of the three ciphers."

The Zodiac Killer's 340 cipher, that followed the October 13th 1969 letter, was three-tiered just like the 408 cipher, but crucially it was structured diagonally for the majority of the coding, as postulated in the newspaper. The title of the newspaper article was Text Of Letter May Offer Clues, but did it offer the inspiration for the Zodiac Killer to create a diagonal shift in his 340 cipher just three months later?


The idea of why the Zodiac did his Z340 that way, is vastly interesting. Even the fact that he had an apparent error in transcription.

Non-linear thinking (either through error or intent) can be so great at confounding.

Chaucer and Snowmman, who am I suppose to believe here your fellows or the FBI?  I accept at face value the FBI's statement this past weekend that none, repeat none, of the Zodiac ciphers have been solved.
Sorry. This is just factually untrue.

The FBI and local law enforcement released statements that the Zodiac case remains unsolved due to Tom Colbert’s claim that it had. There was no mention of the ciphers. The Z408 was solved in 1969 and the Z340 was solved last year. Those are facts.

I looked for such a statement from the FBI and couldn't find it.
They said Zodiac is an open investigation.
As far as I can tell, they didn't say the cipher solutions were wrong. (I'm talking the 2020 solution)
They had previously said the solution made sense.

Do you have a link to something that says the FBI says the Z340 solution is wrong? I couldn't find one.

I always provide links to info I source. Why don't you?

EDIT: Oh I think I get it. You think this latest thing about Gary Poste, which the FBI says is wrong, is somehow linked to the Z340 decode last year.

It's not.

You don't seem to understand this latest Gary Poste claim, and the Z340 cipher decode last year, are two different things.

You didn't read the FBI denials close enough.

Dedication ?  ::)

well, "dedication" seems like blind adherence to some dogma.

McNeely summed up his rationale/motivation himself:
 
“So, the question is; Do we stand up and take the risks and have a blast enjoying our passions?
Or, do we hide in the shadows, being afraid of what might happen if we are so bold [as to] to follow our dreams?”

and he also said:

'There's a saying I really like: “I refuse to tip-toe through life only to arrive safely at death.” That perfectly sums up my attitude.'
