Mini-submarine AS-28 lifted to the surface at 07:26 a.m., Moscow time,with all seven crew members

LOL.

"Komrade Kaptitan, we need a rescue sub."

"Dumbsky shitsky Ivanovitch, we ARE the rescue sub!"

"On 30 October 2004 he dived to a depth of 171 m, in Villefranche, Nice, France; surpassing his previous record by 9 meters. The current women's record is held by Tanya Streeter, who dived to 160 m (524.8 feet) on 17 August 2002. The unofficial records are held by the late Audrey Mestre (166 m) wife of legend Francisco “Pipin” Ferreras; she drowned whilst trying to set a world record of 171 m (561 feet). "

Thanks for this info. So, if a male can 'free dive' 171 m (560 ft) and sucessfully return to surface, it seems like maybe 600 ft is near the 'escape' depth for a 'free ascent'?

A breath of fresh air!!!!!!!!!!!!!!

Where is Drudge? Geez...even my local news has the story.

[GopherIt]

You can't bring me to say 'superior' ;>) ... but I'd say we've all been blessed to see the best.

[Shortstop7]

Awesome! That's all we need to know. A joint effort...and I'm so thankful they are safe and alive.

Good job to all for the joint effort.

Let's not go "overboard" ;^)

Yep, that's what happens to Navy pilots that don't have successful takeoffs.

A friend of mine was a Navy pilot that flew the mail/delivery plane out to the carriers (sorry don't know the number of that type of aircraft). She has been out for many years and is now a stay at home mom. I wonder if she still has her private pilots license.

But I have a question, if the Brits and the Russians are there then why are they being examined/treated by a U.S. doctor?

Because the Brits have socialized medicine and there was no slot open till October?

[Imperialist]

Just out of curiosity, who primarily developed the Scorpio 45 that did the rescue? A google search was not very clear, too many news hits right now.

From what I hear, our Navy is now implementing some advanced submarine escape suits. I don't know how these new suits work, but I would assume that they just keep you from drowning, not from feeling the pressure of the sea.

The older masks (I can't remember the name) basically kept your head covered in air. Before you escape, you pressurize the escape compartment up to sea pressure. Then you escape the submarine through the hatch and keep on laughing "ha, ha, ha" as you ascended to prevent hurting your lungs (if you don't, your lungs will be destroyed due to the difference in pressure between the air trapped in them and the lowering pressure of the sea as you rise). Depending upon your depth, you had to pressurize faster and escape faster to prevent yourself from getting the bends. If you took too long, enough nitrogen could be dissolved in your blood to kill you.

The key parameters on whether you could survive are air reserves on the submarine (to pressurize the emergency escape trunk), your depth (on whether you could survive the ascent and the bends afterward), list and trim of the submarine (so that you could actually operate the hatch and pressurize), how many people have gone before you (because you have to vent the high pressure air from the trunk into the submarine), and most importantly--environmental concerns. If you are 20 miles from land, noone knows where you are, and seawater temperature is only 30 degrees, you might as well stay in the submarine.

I would say that it would be possible for them to survive 600 feet with doctors and equipment around--but they are really at the far end of the survival spectrum. Any deeper or without the assistance and they would likely be doomed.

Bump, great job to everyone invovled.

I admit I don't know much about this. I saw a tv show about free diving once and that is the extent of my knowledge. Submariners would have very serious and most likely fatal problems with decompression. These free divers are down and back up like a rocket. Something like 3 and a half minutes. They carry a lot of weight down with them and let it go when they hit their mark and shoot back up. So not much time for nitrogen bubbles to form, plus they are extremely well conditioned for this effort, while submariners would have little if any training.

[Kirkwood]

Drudge has seen better days. I have been very disappointed with him lately. He doesn't take his job as seriously as he once did and I have to wonder about the quality of the people he has working for him.

[burzum]

Submariners train at Sub School on how to ascend. On the submarine, the air pressure is relatively close to atmospheric pressure regardless of depth. Prior to ascending you increase the air pressure briefly in a rescue hatch so that you can open it and then quickly ascend. If you do it correctly and you are at a shallow enough depth, you can survive. The time that you are pressurized at or near sea pressure for your depth is what you have to minimize (because it is during this time that nitrogen can dissolve in your blood in higher concentrations). You can't pressurize the trunk, sit and wait 20 minutes, and then decide to ascend. If you do, you are dead.

"I would say that it would be possible for them to survive 600 feet with doctors and equipment around--but they are really at the far end of the survival spectrum. Any deeper or without the assistance and they would likely be doomed."

I'm sure you are right about the water temp, if there is no rescue ship above at 30 deg., you are dead within +/- 15 min anyway, but it seems like if there are athletes free diving down to 560 ft. then everyone should be researching submarine escapes at similar depths. (I don't know what temps they make these record dives in). After all, I believe that these "free dives" are with NO equipment.

[Kirkwood]

Thanks for the info! The Navy offered me a commission to go with submarine duty, but I wanted naval aviation. For some reason, flying in a metal tube at high altitude is easier to deal with than cruising in a metal tube under hundreds of feet of water.

I'm not sure if the sport free divers wear air bladders or something special to make them rise faster than normal to the surface, but I believe they do, at least when they are first training.

[Atchafalaya]

Has much potential, I'll think about it tomorrow when I'm rested, awake, lucid, with it, yeah, oh yeah, uh huh, yes I locked the door, mmmm baby zzzzzzzzzzzzzzzzzzzzzzzzzz!

Here is a photo of Tanya Streeter. She has great lungs.

Kidding aside, my prayers were answered. Who cares who got those men up; the good news is they were rescued!!!

[Hank Rearden]

Now that he's rich and famous, he basically takes Fri/Sat off to party and schmooze, I think. Plus, he has to dredge up useless crap to siren about for his Sunday radio gig - like what Rupert Murdoch's family is doing. As if we give a sh%$ about it.

You gotta wonder about his "staff", though - he doesn't do it alone, but the rest must be drunk on a back deck or something.
