Cooper can't be a loner? or easily get to PDX without being noticed, or traced?

The FBI admits it's the most probable place he jumped, but since no data has surface we can not determine whether the path is correct, or the timing of the jump. none of the other copycat hijackings had anything to do with wild rides getting away from the dropzone. the FBI now believes it's possible the jump was further south, which brings you closer to the river.

How hard do you really think it would be to parachute and leave the area? he had a good head start on them. Tosaw believes he went into the river, he's not the only one who has this theory. lets not forget about the path possibly being more eastward into the Washougal area, or R99's theory of the path westward? 

Cooper tried to get the stairs down very early in the flight, do we automatically discount an early exit? if you don't, then you left your boys behind where they thought they should of been to pick him up?

Did he know the plane would fly over Ariel, and near the dam? I don't know. the known evidence doesn't point to him have any idea where he was. did he know the best case to jump from the stairs, freefall, or deploy off the stairs? it's all speculation due to not knowing the knowledge he had.

Nobody ever thought getting off Alcatraz could be as simple as catching a ride on the same boat that brought them to the island. it sounds plausible, is it true? time will tell. for years they have tried swimming across the bay to prove it could be done, when it's possible none of that matters what so ever if the new theory turns into fact.

Not necessarily. Even the whole bag of money would have been shredded then compacted into a relatively small space very quickly,

Possibly, but it's a pump, not a shredder. it doesn't have sharp blades. they are impellers. it's designed for suction.

Shutter, here are my replies.

Cooper can't be a loner? or easily get to PDX without being noticed, or traced?

Maybe he was seen, but he wasn't traced.  No car at the airport, no taxi cab driver witnesses, no finds at any local hotel/motels.  Just because he was seen doesn't lead to anything.

The FBI admits it's the most probable place he jumped, but since no data has surface we can not determine whether the path is correct, or the timing of the jump. none of the other copycat hijackings had anything to do with wild rides getting away from the dropzone. the FBI now believes it's possible the jump was further south, which brings you closer to the river.

It seems that no one questioned the flight path until the money was found.  Now, since everyone assumes he died in the jump (or soon thereafter), we must adjust the flight path.  Since the jet was on autopilot, it would have only deviated a small distance from Victor 23.  Robb Heady, one of the copycat hijackers was caught when the FBI found his car.  Roadblocks work!  Cooper anticipated these, even though they didn't materialize soon after his jump.

How hard do you really think it would be to parachute and leave the area? he had a good head start on them. Tosaw believes he went into the river, he's not the only one who has this theory. lets not forget about the path possibly being more eastward into the Washougal area, or R99's theory of the path westward? 

Cooper has prepared for the worst.  If he has a bad landing and drifts further away than planned, he may need several hours to get to an escape vehicle.  If that is a car, there could be roadblocks by then.  He decides to take the more elusive escape route down the river.

Cooper tried to get the stairs down very early in the flight, do we automatically discount an early exit? if you don't, then you left your boys behind where they thought they should of been to pick him up?

According to Sluggo's timeline and the FBI interviews, Tina is in the cockpit by 7:42, only a few minutes after takeoff.  The aft stairs are down shortly after that.  By 7:53, the 727 is at level flight at 10,000'.  At 8:05, the cockpit contacts Cooper and he responds.  Cooper jumps at 8:11, almost 30 minutes after the stairs are down.  Why does he wait so long?  Because he is waiting for the avionics to indicate his predetermined point of departure.  Note again, Cooper is elusive as for 30 minutes, no one other than Cooper is in the aft section of the aircraft.  No one has any idea what he has in his paper bag or that he has avionics in his briefcase.  This is all cleverly hidden by Cooper.

Did he know the plane would fly over Ariel, and near the dam? I don't know. the known evidence doesn't point to him have any idea where he was. did he know the best case to jump from the stairs, freefall, or deploy off the stairs? it's all speculation due to not knowing the knowledge he had.

You need to read my book.  With the specified altitude, and the cascade mountains to the east, Victor 23 was almost the default route to fly.  This has been mentioned by others as well.  Being on that route, all Cooper needed was to monitor his avionics until he got the predetermined reading he needed.

Nobody ever thought getting off Alcatraz could be as simple as catching a ride on the same boat that brought them to the island. it sounds plausible, is it true? time will tell. for years they have tried swimming across the bay to prove it could be done, when it's possible none of that matters what so ever if the new theory turns into fact.

With a month or so to plan this caper, and the time to test all the phases of the plan (with the exception of the jump), this really is a fairly simple plan.

Is there ANY way that the Ingrams could have planted the currency (or been shown where it lay) and led Brian to the spot AND ALSO have the currency shard field documented in the TV news segment that Georger posted?

I don't see it, but Maybe Bruce can do some remote viewing, channeling or just plain imagining out of the box.  ;)

377

I'm trying to think what reason Dwayne Ingram would have had for concocting a story about how he found the money.

It seems he realized (pretty early on) that it was likely the Cooper money.  Did he think he couldn't just return it to a bank (it would be identified), so he figured he'd have more public sympathy to a claim if it was an 8 year old that found it?

If that's the case, it seems to me he was right.  I'm not a lawyer, but from my couple of law classes the insurance company would seem to be the rightful owner of all of the money -- or at least its cash equivalent.

It seems he realized (pretty early on) that it was likely the Cooper money?

He didn't. This has all been explained before, in detail (using FBI summaries). Read the thread.
I guess it depends on what is meant by "pretty early on".  The money was found on Sunday, February 10.  The FBI was notified, assembled a team and began digging on Tuesday, February 12.  Regardless of what the thread says, it's impossible for the Ingrams not to have realized it was Cooper money within hours -- not days.

Actually it was days!

They didn't have the faintest idea what they had until someone in law enforcement requested they call the FBI. The Ingrams were not global trend setters but Arkansas Hill people living in their own small world in Vancouver, praise Jesus! These Entanglement theories that the Ingrams were enlightened people in touch with DB Cooper in their circle of mysteriants is absolute fiction - a formless satire invented by people with nothing better to do and no more imagination than a frog. 

These people were relatively new to the area and didn't even know Tina Bar existed until somebody told them about it. Harold had a warrant waiting for him back in New Mexico. Following their find they spent hours trying to clean and separate and dry the money on their kitchen table for presentation to a bank (for redemption). Everything changed when Harold went to work on Monday and started confiding in a few people. This lead to Harold calling law enforcement and they recommended he might call the FBI ... the rest is documented history.

But don't give us this B.S. that Harold or the Ingrams realised quickly what they had - they didn't! By all accounts they had barely even heard about the Cooper case being new to the State.     

Please publish your interviews with the Ingrams so we may all share in your news?

nothing remotely linked to any device for monitoring aviation was seen in the case. this is 1971, highly unlikely something so compact was available. the path has been in question for a long time. stating nothing prior to the money find isn't plausible due to technology of that time. it just wasn't discussed like today.

Do you know Jo Weber?

Here is a vintage DME unit.  It is about 6.3" wide, 1.3 inches high, and 12.25 inches long (see specs).

Now take away the metal enclosure box, the plastic face plate, and any other unnecessary clutter for this mission, and you have a briefcase-mounted DME.  Not as big as you might think, and definitely not recognizable by anyone not skilled in avionics.  It just would look like a "mass of wires".

I don't know Jo Weber, and I don't believe any of the "suspects" brought forth to date are the real Dan Cooper.

Bill,

Your "vintage" Bendix DME above is WAAAAY later technology than 1971. Aircraft mounted DME, unlike passive VOR sets, is an active system, has a transmitter and receiver. The transmitter takes a considerable amount of power. I also question whether it would work without an externally positioned antenna. Fuselages are pretty good RF shields.

I got my BSEE from UC Berkeley in 1972, so I am reasonably familiar with early 70s state of the art in electronics/avionics. In my opinion there is no way Cooper had a briefcase contained DME interrogator and readout in 1971.

Bill,

First, let me say welcome to the thread and you certainly seem to be more stable emotionally than Bruce Smith was indicating recently.

Basically, in your statements above you are assuming that Cooper knew his location when he jumped.  Actually, the airliner was above a 5000 foot overcast and several lower cloud layers and it is very, very unlikely that he could estimate his positon to within a radius of 20 miles.  Your statements require pinpoint position information and Cooper simply did not have that and could not make the various segments of the trip in the general time frame you propose.

Several years ago on the DZ thread, if I remember this incorrectly would some of the former DZ posters correct me, Amazon indicated that the Lewis River between the Merwin Dam and the Columbia River had areas that were almost impassable for even small boats.  And trying to do this at night would greatly complicate the matter.  From the Merwin Dam area, it is probably about 30 miles to the Columbia River and then about another 20 miles upstream to the Tina Bar area.  At best, it would probably take at least five hours for that segment of trip.

In the Portland Airport area, I presume that the road adjacent to the Columbia River is the one you are referring to.  I drove over that very road a few weeks back and I spent several hours shopping at a mall that is located between that road and the Portland Airport.  It would be quite a hike for Cooper to walk from the Columbia River to the Portland Airport terminal.  He would have to take a lengthy walk down the I-205 area east of the airport and then approach the terminal area from the southeast.  That would be a lengthy walk and someone would probably have remembered seeing him and mentioned it to the FBI.  Very few people arrive at airport terminals after walking five miles or so.  And he certainly could not have climbed the airport fence in broad daylight without the tower and security people seeing him.

So to make a long story short, may I suggest that your ideas need further work.  Good luck.

Robert99

Robert,

First, regarding Cooper's jump, think about this from the perspective of an engineer and instrument-rated pilot (which I am and I believe Cooper is as well).  Why wouldn't you jump on a clear moonlit night?  Seems much easier, doesn't it?

Surely jumping on a clear night simplifies Cooper's task, but what about the chase planes?  Cooper knows there will be chase planes, so he can't jump on a clear night because they will see him and report his position as he descends on his parachute.  Before he knows it, he will be surrounded by police, FBI, helicopters, etc.  The clear night jump leads to an easy capture and Cooper knows this.  Thus he selects a night with basically zero visibility above 5000', but clear below with 10-15 miles of visibility.

So since aircraft use avionics to determine their position when flying, Cooper configures some avionics device to determine his position.  I believe it is DME (distance measuring equipment).  DME was the latest and the greatest in 1971, but it could have been a standard NAV or ADF (automatic direction finder).  Either way, Cooper knew exactly where he was from the avionics in his briefcase (battery(s) and mass of wires).  I believe Cooper took a half a dozen trips from PDX to SEA in the month prior to the hijacking, testing this equipment.  He had it calibrated to work, you can be assured.  And next look at where he was projected to have landed.  From the FBI Landing Zone Map at Sluggo's website, it is estimated that he jumped at point A and if he pulled his ripcord soon after the jump, he landed at point B.  So Cooper's plan was to drift towards the well-lit Merwin Dam, land in the fields south and west of the dam, and then walk a short distance to the Lewis River.  This isn't an accident!!  If Cooper landed 20 miles north in Pigeon Springs, which looks like an area with logging roads and timber harvests, I would agree that he jumped blindly.  But seeing the precision with which he jumped and drifted, I realize this was his plan (Cooper is a pilot, so he has the same winds aloft data as Northwest, so he calculated his drift distance and jump point earlier in the day).

I believe that the Lewis River is navigable from the dam to the river, if you take the correct route.  At one point the river splits, and one branch has waterfalls, I believe.  One map I saw showed mile 21 at the dam, so it is about 21 miles to the Columbia.  From there it is only about 8 miles to Tena Bar.  But you are correct, this trip will require a few hours in a small craft like a 12' aluminum boat.  The advantage, though, is that he avoids any roadblocks and is miles away from the dropzone in a quiet rural area when he arrives at Tena Bar.  Be assured again that Cooper has made this trip numerous times in the month prior to the hijacking.

I don't know what PDX was like in 1971, but there may not have been a perimeter fence.  Also, where Cooper is a pilot, he may have known of a more direct route to the terminal.  The economy parking lot today is about 1-1/2 miles east of the terminal, but they provide a free shuttle service to the terminal.  Did that parking lot and service exist in 1971?  I'm not sure of this next tidbit, as there are limited aerial views of the airport in 1971, but the I-205 bridge appeared to be under construction at the time.  If you check Google Earth, you will see several marinas along the Columbia in the vicinity of the airport.  One is almost directly across from the terminal. 

According to Google, it is at best a 2.8 mile walk to the terminal from the I-205 bridge, and takes about 1 hour.  And even if people saw him, it wouldn't necessarily lead investigators to a boat!

Again, Cooper has surveyed PDX and made the trip from Tena Bar to PDX numerous times in the month prior to the hijacking.  He has a plan!

I am a retired aeronautical engineer and general aviation pilot with a limited amount of skydiving experience.  I also held, at retirement, both Advanced and Instrument Ground Instructor Ratings.  I owned general aviation aircraft in the 1960s and 1970s.

There was no navigational device existing in 1971 that would have been of any particular use to Cooper under the circumstances of his jump.  It should also be remembered that Cooper showed the contents of his brief case to Tina (and/or maybe Flo) and she did not see anything except a battery and sticks of something (dynamite or road flares).  Consequently, there is no evidence whatsoever that Cooper had any electronic device with him.  The small paper bag that Cooper had with him was reported to be about the same size as the bag that today would be used for a single take-out Big Mac from McDonald's.

Cooper's hijacking was NOT well planned since, among other things, he was not dressed appropriately for the weather conditions that he would encounter on the ground.

Also, I believe that some of the distances you estimate are incorrect.

Perhaps no electronic device but a mag compass and a stopwatch could have been used to dead reckon. You'd be guessing on ground speed but you could plot a track if you noted every turn and the time between turns. A mag compass works just fine inside an aluminum fuselage.

Handheld VOR receivers showed up in the late 80s:  You are not allowed to view links. Register or Login

Nothing remotely like this was available in 1971 as far as I can tell. I am told that these hand held VOR receivers don't work that well inside a metal aircraft and need to be connected to  an external antenna.

But don't give us this B.S. that Harold or the Ingrams realised quickly what they had - they didn't! By all accounts they had barely even heard about the Cooper case being new to the State.

I don't think I'm reaching here on this one.  I'm just looking at a calendar.

Ingram says they found the money in the afternoon on Sunday and the FBI showed up at the site on Tuesday.   Are my dates wrong?  The time between them finding the money and them contacting the FBI -- less than 24 hours -- would seem to qualify as pretty quickly.

You've expressed some skepticism with Dwayne's story.  Now, if you're suggesting he actually found the money sometime before February 10, then I might agree with you.   I know they tried bleaching the money and tried to figure out what to do with it before calling authorities, but unless my dates are wrong, I see that as "hours" not "days".

I received a Sporty's Pilot Shop catalog yesterday that offers the Sporty's SP-400 hand-held nav/com for $329.00.  It includes the com/nav/loc/ils and NOAA frequencies and can be operated on AA batteries plus other power options.  It weighs 16 ounces.

This might have been from the History Channel - Case Closed, but not precisely sure.

Columbus made it to the western hemisphere with a magnetized needle on a straw floating in a bowl of water.  No time piece (hour glasses don't count here) and probably an astrolabe (primarily to measure the angle between the horizon and the sun in order to estimate latitude).  People who have studied his navigation on the trip west estimate that he was probably trying to maintain a constant latitude.

Here's the time line from page 109 of Himmelsbach's book:

1.  The Ingrams found the money late in the afternoon of Sunday, February 10th.

2.  Dwayne Ingram talked about the money at work the next day, Monday, February 11th, and his co-workers told him to call the FBI.  He did and Himmelsbach made an appointment for him to be at the FBI offices at 9:00 AM, Tuesday, February 12th.

3.  It is not stated exactly when the FBI agents first went to Tina Bar, but it was probably on Tuesday afternoon.  The main search effort seems to have been made on Wednesday, February 13th, and Thursday, February 14th.  And apparently the search was suspended after Thursday.
