Someone posted a hi def screen cap over at the Fuselage.
Someone pointed out that a note at the bottom looks like it says “Missle CVII inactive since accident”.
Looking at that a little closer I think it says
Possible CV II inactive since accident. Now is CV more Roman Numerals or is it initial for something?
Well that’s the kind of blinkered pig ignorance I’ve come to expect out of you noncreative garbage…
Can someone remind me what the tailies hatch was?
Interesting that there seems to be an unconnected little hatch right next to the Swan.
And that doesn’t look like “Missile” to me. Maybe “possible” or “popsicle” or “fossicle” or something, there is definitely an extra squiggly letter in there between the le and the ss. It is also right next to the Swan, whatever CVII is…
is that any clearer? Looks more like “possble” now.
Oh my prev spoiler was WRT all of the previous spoilers (what does the map say?).
Also on the same line:
I hope it says “popsicle.” That would be really refreshing on a tropical island.
I concur, for what it’s worth, about the text.
CVII could mean 107; I can’t think of anything it would stand for. Besides curriculum vitae. “Curriculum vitae inactive since accident” … well, if you were hurt in an accident, I suppose you’d put off updating your CV for a while.
I’m seeing a CV I, a CV II, a CV III, and CV IV, the last of which would seem to preclude the CV being roman. There are six stations, same as the training video. But a seventh is scribbled out, and there seems to be an additional central station. They seem to be arranged within the dharma octagon as though there should be eight. The swan seems to be the biggest although that could just be because the person who drew the diagram got to see the swan the most. The top left station appears to be the caudaceus station that Claire was in although I can’t make out what is written, and seems to have it’s own hatch. The top right definitely says arrow, and is on the opposite side of the island as expected. All the stations seem to have no longer accesible tunnels that led to the central station. And it appears that the blocked off corridor in the swan station has a hatch, so maybe it’s accesible from the surface. The two on the right seem to be undetermined, but the one on the left seems to be discovered. A worm or blobby thing. Says something like Neptune. Maybe it’s aquaman riding his seahorse 
There seems to be a lot more to the arrow station than we saw.
All of the stations have tunnels headed towards the center, which end in big “X’s.”
I suppose it’s safe to assume that we saw the Swan’s blocked access, when they went down into the basement and found an area that had been sealed off with eight feet of solid concrete, like at Chernobyl.
Big “?” in the middle, which all the stations were presumably linked to, until the “incident?”
What I am gathering from looking at it and reading other comments on the Fuselage is
The one to the left of the Swan is indeed Neptune with a figure on a seahorse. Going clockwise from there is The Staff, with a caduceus. Then a scratched out one, The Arrow, and the next two seem to be in doubt due to the dotted lines and what looks like question marks in them. Off to the side from Netune it looks like the word “Activity” but I can’t read the rest of it. Between Neptune and Swan there is something written that looks like Latin. Others on the Fuselage have determined it to be “Cogito Ergo Doleo”, something like “I think, therefore I suffer”.
I think Kelvin did a lot of that drawing. Didn’t Desmond say that Kelvin was always out exploring the island?
All the stations except the Swan. That bunker has access to the “?”, which I assume represents “the answer”.
Did anyone notice the pun in the title" Lockdown = Locke Down.
I did HiDef freeze frame on the hatch diagram, but it’s too hard to read. There are lots of Roman Numnerals of the CVII variety, but more ineresting is lots of cursive writing which is impossible to decode. Or at least it was impossible for me. I suspect The Tailsection (see link in OP) will be the best place to find decoding efforts.
And of course the safety deposit box number 1516, is almost not even worth noting these days.
And we all knew that there was a real Henry Gale but our “Henry Gale” isn’t Henry Gale.
Jack did call it a parachute, and on further viewing, I see no burners. BTW, the “cereal number” [sub]har[/sub] on the Mac n Cheese supper, is the same as that on the cereal that Locke eats in the hach. It is dI9fftr731.
I don’t know if the vid is legit. Could be a fake. Who knows?
What does “Lit sit magna tamen certe lenta ira decorum est” mean? That’s my best read on the image.
I’m guessing something along the lines of “Does it mean as much as we think it means”.
If it means that, I’ll die happy.
Actually, it looks to me like the Swan is cut off as well as the others. There’s a small ? between the Swan’s X and the main ? just at the end of the dotted double line.
Just keep saying enhance. It works on TV.
I was actually just about to post the same thing myself.
As someone who experiences occasional severe paralysis of the legs, I was really feeling for Locke when the flesh-skewers (thanks, Larry Mudd – can’t wait for the rotating knives!) came down. One day you’re healthy, then you’re in a wheelchair. Then the Island cures you, and next thing you know you’re trapped under a blast door. 
I got the whole Lockdown thing, but I was thinking we were going to find out how Locke went down (his paralysis).
He is one of the few characters whose story has a large gap between flight time, and the previous time we saw them. Or, I think we know more about the other main characters’ situations just prior to flight time. Crap, we still don’t know how Locke got paralyzed, but we know the stories of the others just prior to flight.
Damnit. Did that make sense?
Damn–one of the best cliffhangers in quite some time. That story and the finding of the balloon and grave were just too pat, too easy, to be completely on the level.
More nicknames from Sawyer: Amarillo (?) Slim and Coolhand for Jack; Mongo and Muttonchop for Hurley. (Remember, everyone?: “Mongo only pawn in game of life.” )
Tagalong Kate is back again.
Who’s got abandonment and rejection issues? Locke does, Locke does. And why are his legs such a target? Poor buggar.
Regarding the writing:
Ut sit magna, tamen certe lenta ira deorum est."
The wrath of the gods may be great, but it certainly is slow.
And other things:
“susum corda” is “lift up your hearts” and is normally repeated.
“Malum consilium quod mutari non potest” - It’s a bad plan that can’t be changed.
I just spent an hour trying to read those scribbles, and they’re Latin? No fair, Lost writers! 
Another thought, the two ‘dotted’ hatches are perhaps in the Others sector of the island. Not sure if anyone pointed it out, but “Arrow” is surely the Tailies bunker.
I’m sooo stealing half the credit for that one.
