Is anyone else watching this.. Fingers crossed but its all looking hopeful!

(psssssssst - I mean the Chilean Miners)

oh thank you!!

It's on CNN, and CNN.com will be streaming it.

I am watching it on BBC and normally BBC has pretty good reporters, but the guy on at the moment is laughably bad.. ABout two mins ago he said

"Were here live in Chile, and its starting to get very.....ummmm, chilly"

LOL - best one yet...

"The miners will soon be out after 68 days underground to be reunited with their wives and husbands...well, not their husbands"

you couldnt make this up.. Comedy gold!!

Do they have to worry about the bends?

im not sure the air pressure it that high...

They are actually bringing them up slower than they can to allow for decompression.

i thought ascent was 12-15mins, that not slow enough for decompression, of course im basing this on old deep sea dives, where the pressure is probably much higher.

there are giving them sunglasses though, they need to look cool for tv :p.

actually its to protect there eyes from the sun they haven't seen in all that time.

It's nighttime, so they don't have to worry about the sun for the first few. However, I assume that all the flash photography will be worse than the sun!

I'm so excited to see them coming out. I hope everything goes exceedingly well! What a horrible ordeal...

I wouldn't think that there is enough pressure differential to make more than an ear pop or two in 2,000 ft of air column and certainly not enough to need to decompress. It would be like expecting to have to decompress after driving up a mountain from one elevation to another 2,000 ft above the first. It's possible that they were pumping air into the cavity with enough force to raise the pressure in the mine though.
The place where they come out of the ground will most likely be as bright as daylight with work lights running at night.
I hope the story has a completely happy ending, with no problems in the rescue.

Not even if they have been under for such a long time? I am sure I read that was why it was a slow rise to the surface..

From Wiki:

Leaving a high pressure environment

The principal features of a caisson are the workspace, pressurised by an external air supply, and the access tube with an airlock
When a worker comes out of a pressurized caisson or out of a mine that has been pressurized to keep water out, they will experience a significant reduction in ambient pressure.[14][19] A similar pressure reduction occurs when an astronaut exits a space vehicle to perform a space-walk or extra-vehicular activity where the pressure in his spacesuit is lower than the pressure in the vehicle.[14][20][21][22]

The original name for DCS was "caisson disease"; this term was used in the 19th century, in large engineering excavations below the water table, such as bridge supports and tunnels, where caissons under pressure were used to keep water from flooding the excavations. Workers who spend time in high-pressure atmospheric pressure conditions are at risk when they return to the lower pressure outside the caisson if the pressure surrounding them was not reduced slowly. DCS was a major factor during construction of Eads Bridge, when 15 workers died from what was then a mysterious illness, and later during construction of the Brooklyn Bridge, where it incapacitated the project leader Washington Roebling.[23]

It sounds as if the mine/environment has to be pressurized for this to be an issue; I don't know if this mine is. Certainly, before the accident miners traveled in and out every day, presumably not any slower than they're going to be taken out now, without any issues?

They said on CNN that it's not an issue -- that there's not enough of a difference, but they're still going to bring them up at 1 mph with a possibility of 3.5 mph.

It's coming up now at about 15 feet per second, which would be more like 10 mph, but I have no idea if they have someone aboard or not... they sent it down part way and brought it back up once before.

As Dark Helmet once said:

"[they're] not in there"

I know I know....just going down....it was a test run. :)

The first miner is on his way up!! Should hit the surface in less than 8 minutes!!

Moving very quickly now just a couple of minutes!

Fabulous! They still have a lot of work to do.
