I've been looking into the placard/marker for the past couple days. Hominid told me in a email years ago that most of the planes with the emergency option were cargo planes. just about every plane having the system found were 727-100c. those would be the conversion planes. a large cargo door can be seen on the port side of the aircraft along with looking up the registration number or "N" number. 305 shows 727-51 while a conversion shows 727-22c
The first 727's didn't have the system. this was added later. I assumed it was originally installed and faded out. I'm not even sure the first years had any controls in the stairwell. several documents show where the controls are for the aft stairs and how to operate them. they only show the exterior of the plane having this function. it's also pointed out on the port side of the aircraft. possibly, the ground crew was used to open and close them until the controls were installed in the stairwell. this also explains why a placard is in place directing you to the opposite side of the aircraft for the controls. they were moved.
All the models found were from the years 1966 to 1968. a lot of them appear to have the placard over the access door that was on the port side so you can read the placard when approaching the plane to raise or lower the stairs from the ground. one model was found that wasn't a conversion. this was turned into a luxury aircraft with the N number N30MP and was a 727-21 manufacture in 1966.
Boeing wouldn't need to sell kits for the emergency function if they were direct from the manufacture on all 727-100's from the first day of manufacture. The first commercial flight was February 1,1964 with Eastern airlines flying from Miami to Philadelphia. 305 was an early model with the first flight in 1965.
This doesn't resolve much but gets us closer to understanding a few things and questioning other things. I've only seen one document about two emergency controls inside and outside. most only refer to the normal controls inside and outside. the failure of seeing the placard/marker on any aircraft is also frustrating viewing dozens of planes and zooming in for a look.
I'm not fully satisfied with all the documents, 302's about the placard. yes, I question whether or not 305 actually had the function. it's looking more and more that it didn't.
Flyjack, can you post the document surrounding the emergency option where they explain it's not on all the planes. I can't find the document in my files...I'm interested in the year of the document and the amount of kits which I recall were just under a hundred. only 572 727-100's were made.
Regarding the placard I have to say that there are many unanswered questions.Chief among them:
1) I was told by parts distributor that it came from within the back airstairs cone area.
2) The FBI (meaning the Sheriff working with an FBI agent) reported that it came from 305 and required the door being open to fall out.
3) How the FBI could overlook the fact that 305 didn't even possess the emergency release system utilizing the red T-handle--this would be complete incompetence.
That said, looking at everything that everyone has been able to procure about the system--pics, instructions, schematics--does not appear to show 305 with this system. Therefore, in light of the many other errors the FBI has made in this case, I think it is reasonable to deduce that this is yet another FBI error. Simply put, it doesn't appear to me that the Hicks' placard came from 305. Therefore, cannot be used or considered a credible piece of evidence.
I have no idea where this, apparently interior, placard came from and cannot explain what appears to be a colossal F-up on the part of the FBI, accept to say I've seen this before.
