    I have no idea where the places you mention are so could you tell me why they would be different?
    Even the media are trying to get talking to "cave experts" I just watched one from the states giving his opinion, last I'd known of him before that was that he had managed to get cave divers banned from a popular site because of the damage he'd caused.
    As I understand it, the Thai cave has sections of small underwater passage and very low/no visibility. The depths aren't great, certainly less than 30m. The techniques involve lots of touch contact, use of robust guidelines to actively navigate by hand and limited communication is possible whilst underwater. It is more of a solo-diving mindset, it is very difficult to communicate a problem or have your buddy fix it in these conditions. Getting stuck is a genuine possibility if the line is pulled into a lower height area - a so called 'line trap'.

    The caves I quoted are some of the most popular caves in France for cave diving. They have much larger main conduits - think garage door up to church-sized. The sumps are long and deep. Vis 5-15m. The dive in, and hence the necessary dive out, are trimix dives with significant decompression. People are now regularly exploring beyond the first deep sumps of these caves and run the risk of injury or kit failure. The GUE teams operating in France are well set up to operate in this kind of environment and the safety setup to deal with a problem is significant. Lots of teamwork involved.

    The team at Cabouy are climbing and rigging rope systems beyond a 2km long, 30m deep continuous sump. Beyond that they did 1km of dry caving and then a 100m deep trimix dive. They have built rescue stretchers for the possible underwater evacuation of injured divers / climbers. The list of people able to rescue them from there is pretty short so they took precautions themselves. Map here : http://www.thehiddenriverproject.org...uysse_plan.pdf

    Our project accurately surveying St Georges has been more diving orientated so far, but has now reached the start of sump 3 which is shallower and more like caving. Sump 1 is 400m long, 30m deep. Sump 2 is 1100m long, 75m deep. Then there is a section of dry caving/climbing to reach Sump 3. The ability to self-rescue from this kind of area is essential and we have appropriate reserves in place to do so. Map here : https://www.dropbox.com/s/watp4mkphc..._v1.4.pdf?dl=0

    Ressel is even more exposed at the far reaches. S1: 3095 m (80m deep); S2: 434 m; S3: 89 m; S4: 5 m, S5: 242 m; S6: 1335 m. http://plongeesout.com/ressel_new.html

Full day Saturday at RAF Sealand with the VGS (lolling about in the sun, occasionally holding a wing tip level and running like hell for the first 20m as the winch pulled, before the wings found lift - for a flight or two in a glider at the end of the day). We had a DofE Section as well. They even did the Ten Tors once.

    I am actually starting to pity my daughter now.....
    OMG- Birkenhead School ?

    When ?

I look forward to sharing a beer with any of them next time I see them, and giving them my congratulations and thanks.

    p.s Two of the UK GUE instructors are also members of the CDG, and the others all have more sense
    John
    No joking on my part, it was a genuine question, I know that there were volunteers from Australia there and they could have been GUE.. for all I know..

    Clearly not a time for banter.. donít be so quick to go on the offensive please
    Bacon is good for you!.....................................

    Confirmed 10 boys now out of the cave. If I’m honest whilst holding hope I was finding it difficult to be too optomistic. This is really quite stunning news. A possible 100% result? How bloody good would that be?

    79-85 - missed you !

    but i remember the smell of cordite at Chetwynd range and the declaration as you left "I have no live rounds or empty cases in my possession, Sir"

    agreed, but not 100% though - let's not forget the poor guy who died

    It is exciting though, and it is a huge result - didn't mean to diminish that - I just can't help but wonder if that poor guy's death was preventable

    The rescue is rumoured to be finished with all having been extracted and in reasonable health.
