Validity of underground bases and tunnels in particular.
As many here have researched underground bases and tunnelling systems from many sources, Phil Schnider comes to mind, have raised some questions.
The monumental task involved in these constructions need looking at. Phil, from memory said they used high tech laser cutting equipment allowing them to carve through enormous amounts of rock, liquefying material along the way, I cannot remember all the details…
Here is an example of known methods of tunnelling as detailed with the newly connected Swiss tunnel.
SEDRUN , Switzerland.
A giant drilling machine punched its way through a final section of Alpine rock on Friday to complete the world's longest tunnel, after 15 years of sometimes lethal construction work.
15 years, 2500 workers. Cost so far estimated at 15 Billion.
The 57 kilometre highspeed rail link, which will open in 2017, will form the lynchpin of a new rail network between northern and southeastern Europe and help ease congestion and pollution in the Swiss Alps.
It is the third tunnel to be built through the snowbound St Gotthard area but it is much the longest and three kilometres longer than a rail link between two Japanese islands , the current record holder at 53.8-km . Passengers will ultimately be able to speed from the Italian city of Milan to Zurich in less than three hours and further north into Germany, cutting the journey time by an hour.
To see the work in progress, it is necessary to travel two kilometres underground, to the construction site between the southern Swiss towns of Faido and Biasca.
The scale of the work going on is enormous: 2,500 people are working on the tunnel, 24 hours a day, 365 days a year. Besides the two main railway tubes, the construction workers have to dig access tunnels for people and equipment.
Huge fans ensure a fresh supply of air and cool things down. Yet the temperature is above 30C.
"We've got two-and-a-half kilometres of Alps above us," explains engineer Albert Schmid. "That means millions and millions of cubic metres of earth pressing down on us, that increases the pressure and the temperature."
This above, gives us some idea as to what is involved with this type of engineering.
So…these alleged tunnels systems connecting many underground bases using high speed travel systems becomes hard to believe and worthy of discussion.
How on earth do you keep so many workers quiet, to sign disclosure agreements, years of construction, accidents, deaths along the way?

Re: Validity of underground bases and tunnels in particular.
I've wondered the same thing, myself.
Basic geology is quite clear in stating that the temperature of the Earth's crust begins to increase after around one mile, leading to some pretty steamy temperatures at depths of five or six miles. I've heard interviews where researchers, or whistleblowers, claimed to have worked in bases several miles deep, but I do wonder if that's even plausible, as the surrounding ground would be quite hot.
It's possible that there are alternative, high technologies being used; and it could also be possible that the bases are only about a mile or so deep; as even whistleblowers are subject to gossip and exaggeration.
As for the construction of these tunnels and bases, I would assume that most of the tunnels, and likely many of the bases, utilize preexisting cavernous sites. I'm a bit skeptical of claims of vast tunnels leading across the country and city-sized underground bases; but I wouldn't doubt there are some tunnel systems being used, possibly carved out of preexisting cave systems, and many underground bases in operation, likely not as large as a city, though.

Re: Validity of underground bases and tunnels in particular.
The enormity of these type of constructions are baffling...
