The stairs lock when using the normal stair functions. if the plane is equipped with the emergency release it will damage the stairs to where it will no longer lock in the down position. it's goal is to release the stairs so people can get out if they are damaged in a crash and the normal controls fail..

The stairs need to be down when parked. it's balanced to where very little weight in the back will cause it to tip..they either use the stairs or a tail stand to support the tail..we call it a pogo stick in construction..

The placard has always been suspect. Remember, it could be from 305. But most likely not.

However, I believe Boeing reported that the placard from 305 was missing when they repaired it Nov. 26 at Boeing Field.

Somebody reported it missing - that my recollection too. Who? Documentation?

It was someone from the day of testing that reported it missing. this was only documented after the placard was found. another report stated after the hijacking...

The placard is like a decal or a bumper sticker. it's not going to come off very easy. placards are known to come off the exterior of aircraft. my guess would be fuel related and wind shear peeling it off over time..

I've been wondering the same thing, G. I guess I've got it somewhere in my files, but until that cute, blond intern shows up to sort things out, I'm reluctant to go looking.

It was someone from the flight crew that did the testing..his memory is sharp as ever..he claims the decal was missing two days later when they did the test.

The hijacking was November 24, 1971. the flight test was done January 6, 1972. the statement was made seven years after the fact..his memory is actually dull as can be. it's almost like he was saying this to backup what was found. no other documentation has surfaced..

The airliner was repaired and back in line service within about two days of the hijacking.  It was flown back to SEATAC on Thursday afternoon November 25th (Thanksgiving Day) and would have been repaired on Friday and/or Saturday.  Since the repairs mostly involved the stairs and their opening and closing mechanism, the placard should have been noted as missing (if it was missing) and replaced during the return to service inspection.

Other placards can be seen in the video showing the stairs. the other problem would be having a placard for an emergency option that doesn't appear to be on 305.

Most of the test crew didn't have anything to do with the plane. most wouldn't be involved until the time for the test..

The stairs were opened long before the area the placard was found. the pressure had settled to hardly any movement on the stairs. the placard should of been found around McChord..

Much like hurricane shutters you have pressure involved. the maximum gap is one quarter inch from the wall. anything more allows pressure to pull the shutter off the wall. the decal is strong, similar to a bumper sticker. I have a problem believing pressure got behind it..

Sounds like a negative load is required to pull the placard off the wall. that would occur when the stairs opened..

turbulent flow? Think of how much a leafblower can do with 120MPH air flow. The turbulence can be as damaging as a constant force.

Yes, wind will seek out weak spots and slowly tear things apart.
