I believe they agreed is was reproduced exactly as to how it happened.

That was my understanding also - but... FJ is saying all oscillations and bump happened AFTER C jumped not BEFORE (his words).  It is clear what Anderson meant by oscillations was fluctuations on his gauges. Then suddenly one large pressure event. Followed by nothing ...

Anderson says: "...but it wasn’t a one time event but a series of fluctuations which attracted our attention.  I saw it first then alerted Scott and Bill, ending in a single pressure event we felt in our ears, and nothing following, not even more fluctuations. We waited to see if something more would happen but it didn’t." 

FJ is saying everything Andy describes happened AFTER Cooper had bailed, not before. FJ is saying no oscillations happened when Cooper was ON the stairs.  FJ is saying all oscillations and bump happened AFTER C jumped not BEFORE (his words). When the crew reported oscillations they said 'it is Cooper probably doing something with the stairs'. The crew thought oscillations were due to Cooper being on the stairs. When the bump happened they said: "there he goes" according to Anderson. FJ says that interpretation is wrong.... FJ is saying Cooper had already bailed clear when oscillations started! FJ seems to be saying the oscillations and bump happened with a second or so of each other. Anderson does not say that! Anderson implies a longer span of time ? 

The corollary is, FJ's version puts the jump at 8:10-12 or before. FJ keeps saying 'the FBI had it right'. Anderson's version is: "When the final bump happened and the oscillations stopped that sealed it. But even then we weren’t sure and we waited before calling anybody." What does Andy mean? Their 8:12 call was delayed and everything happened back before say 8:10 ? That could put Cooper's drop zone in the original position clear up at Lake Merwin like Scott said later!   

The central issue is, what span of time do oscillations ending in a bump happen over?  Seconds, milli-seconds, minutes? FJ hasn't even issued a statement about actual time span. If oscillations and bump happened AFTER C jumped then the time span would be contiguous - seconds. The test photos suggest the door closed in less than a second following the photo before it. Andersons is clearly talking about a longer span of time, not mere seconds or fractions of one second.

Details  matter.     

The span of time over which oscillations/bump happened is crucial, as matters stand now.

Anderson says: "It was the "rate of descent" gauge that detected the so-called "pressure bump."  Two gauges are used to detect the disruptions of airflow.  (1) the Differential Pressure/Cabin Altitude (which serves as a dual function gauge); and (2) rate of climb, or, rate of descent gauge. It wasn’t a one time event but a series of fluctuations which attracted our attention. .  I saw it first then alerted Scott and Bill, ending in a single pressure event we felt in our ears, and nothing following, not even more fluctuations. We waited to see if something more would happen but it didn’t.  These were minor oscillations. We detected on the gauges only.  We just presumed pretty quickly that it was Cooper fiddling with the aft stairs but we weren’t one hundred percent sure because we were already flying dirty, with throttles up and fighting icing and weather.  A lot going on and it wasn’t totally smooth even before the oscillations started. What we noticed was the pattern of the oscillations was continuing and there was a very minor disruption of the slipstream. Scott said at first he wasn’t feeling anything for sure, then a little later he thought  there was more drag and the nose was deviating a little. When the final bump happened and the oscillations stopped that sealed it. But even then we weren’t sure and we waited before calling anybody. "

Anderson does not assign a span of time during which all of the above happened. Seconds? Minutes? Nobody involved in the sled test assigned a span of time to any of this either!

FJ on the other hand says: 'Oscillations and bump happened AFTER Cooper bailed, not BEFORE'. The caps are FJ's. But FJ has not assigned a span of time to his oscillations/bump happening either ? Seconds. Milli-seconds? Minutes? A day? A week? 

You be the judge!   

The "rate of descent" gage that Anderson mentions would almost certainly refer to the cabin pressure gage.  The "rate of climb" gage on the pilot's panel refers to the climb or descent of the airliner and is not connected to the cabin pressure.

It's obvious the stairs would raise and lock easily in the air. this has been known for a long time. the only way I see getting out of the plane unnoticed would be just prior to landing during slower speeds. the steps wouldn't move much under those conditions.

Alternatives have been used for years with this case on just about everything..

What is he referring to with the "combi 727"

Bill was president from 1983 to 1998. it's hard to say what he really knows. the steps will not lower and lock in flight unless you are at slower speeds. the wind will prevent this. if they did jump off the stairs, the would lower just like we have known for some time. that's partially but enough to jump from. they don't really need to lock down.

Is this what we are doing now just attacking everyone’s source? Give me some credit here...Bill was at SAT long before he became prez. Combi aircraft in commercial aviation are aircraft that can be used to carry either passengers as an airliner, or cargo as a freighter, and may have a partition in the aircraft cabin to allow both uses at the same time in a mixed passenger/freight combination. I can email the screen shots of our correspondents and you can judge for yourself. This guy knew his shit and was confident in what he was saying. I don’t see any reason for him to make either. Regardless if you don’t want to entertain the possibility cooper could of simulated a bump with manipulation of the hydraulic controls let’s focus on the bigger take away here and that’s know we know with certainty that there was a 727 out there well before the hijacking that cooper could of learned that the stairs could be deployed in flight. Before talking to Bill all we had as reference to this was that air America video showing a modified 727 with a sheet metal ramp. This bumps suspects with cia connections like Ted Braden and Howard hunt  up the list.

It was public information at the time the 727 went into service in 1964 that the aircraft had been test flown with the stairs deployed.  This includes a 1964 article in the British aviation magazine "Flight".

I am aware of this single publication do you have any other examples besides this? You said includes so I take it there is more? Also was this issue published in the states?

Great info, Nicky. Thank you.

In the course of these conversations the question was asked: who was at Southern Air Transport and what did they know about 727 air drops. The answer is Everett Johnson, who was flying in from the San Juan Islands on the night of, told me that he later worked for SAT and had a co-pilot named Tom Sailor. Sailor told him that he had flown 727s in Vietnam and dropped 20 commandos out the rear of his 727.

I've attempted to contact Sailor, but have been unsuccessful. His last known whereabouts were in San Francisco.

Cabin rate indicator has two functions. the needle for cabin pressure is what he seen. this is measured in lbs per square inch and would detect any changes in the cabin. a hole in the plane with something moving would certainly be detected.

Great info, Nicky. Thank you.

I’ll see if any of the members of the SAT Facebook group know and or have his contact info uncle Bruce! I learned of two pilots that flew SAT’s only combi 727 Ray Arnold and coincidentally enough Rollie Broughton who shares me last name. Unfortunately Ray past away 5 years ago and Rollie did sometime back too this is where I wish the vortex sucked me in earlier because I’m constantly running into dead sources 🤦‍♂️.

Nicky - Over on dropzone the other day Flyjack posted an old article from Parachutist magazine about the stunt jumps from the Treat Williams movie. That article mentions six people who worked on that. As you can see from my response over there, of those six people, I was acquainted with four of them. Of those four, three of them have passed away. The fourth guy, Ray Cottingham, I believe is still around, but I haven't seen him in a few years. I don't do any social media, so I wouldn't know his facebook or anything. I think he lived in the Las Vegas area, but he was a semi-regular at Elsinore for many years. He would probably remember things about the plane/stair issues, and he might be able to direct you to the other two guys or possibly the pilots. If you can't find him on facebook, perhaps ask Daniella in the office at Elsinore. She probably won't give you his contact, but she might forward yours to him.

Thanks DM, I’ve actually had a few correspondence with Ray C when I was trying to track down Jerry Tyson... I got in touch with him through the old school skydivers facebook group. I had no idea he was part of the movie stunt. I will reach back out to him and report back. Do you have the names of the other 2 you didn’t recognize? You should really consider getting on Facebook if anything for the old school skydivers group. I think you’d enjoy it!
