Appreciate your use of the term 'the old chap', although I hope you are meaning in the sense of example 1 (below), rather than example 2 (taken from Wiktionary).
Oh dear. Such is our language demeaned by alterating the meanings . I got told off for using the word " dosser " on Facebook when in my day it just meant somebody sleeping away from home. I shall revert to " Uncle Brian " as he is rather avuncular and nothing like a dick at all.
Attending. Me, Nigel , Pete, Peter , Nigel and Mike.
With the winch four were happy at The Pit. Peter poked prodigiously at Poker's Progress revealing more of " the arch ". Mud filled with a solid waterworn bedding roof. Rocks and mud in the floor. To me it improved prospects here but not all agreed. At least it could be worked with a team of two capping if numbers were short.
I spent the day lying in the puddle in the tube tub hauling. Loads came out from below now neatly stacked along the tube. Nigel had to prop the big boulder part way up as it wiggled a bit. A horizontal prop would be good then the ladder can be attached. Moving forward the fault rift narrows to 200mm. Using my torch I can look forward in solid rock to more small rocks a metre ahead. On both sides its possible to detach slabs from the walls which will widen the rift to maybe a metre. This was started on the fault wall but left bits undermined further up. I guess they could be pinned or propped horizonally . If every thing is secure we could move forward perhaps a metre next week just by widening the rift.
A productive day in The Pit at QWUH . Ladder installed with more scaffolding and a metre of new passage discovered ( only by remote camera ). Well this is Mendip.
Where no human has ever crawled, grovelled or even seen . Mendips latest new passage ( ish ). A metre wide and a metre plus long. Like I said almost amazing for Mendip. Remote camera view.
Hidden lava tunnels on the Moon and Mars could one day shelter human explorers, offering natural protection from radiation and space debris. A European research team has unveiled a bold new mission concept that uses three different robots working together to explore these extreme underground...
