Yes you can.
The more I watch TV documentaries by Doctors, the more I am confident that it is possible to be over-educated.
Today is a good example -
Structure (large building with thick walls and no windows)
Inside structure (small rooms separated by walls)
I am no brainiac but does this not SCREAM arms bunker to you.
The next question they asked is why small rooms with thick walls, duh, to limit the damage and lower the risk of a major explosion.
One mystery I would like solved involves a bunker in Belgium that two boys fell over, they went for a walk in a local woods and tripped over two metal pipes in the ground.
I have no firm proof, only a hypothesis that fits the known facts.
The boys found a series of tunnels that had got involved in a fire; the walls got covered in soot; what had happened was not cataclysmic enough to cause damage to the structure of the tunnels. The tunnels had been opened since the 1970s as the peace slogan used by the CND had got painted on the sides of the tunnels.
After some research, I found out that the area got used as a tank training ground before the invasion of Belgium in World War 2.
Tanks are notorious for churning the ground up, that's why the American stopped using slit trenches; so in the years after the war, the Belgian government reforested the area to aid the recovery of natural growth.
Woods and forests provide a level of self-fertilization with leaf droppings, however, produces Methane gas.
As anyone from a mining community will tell you, this gas can be deadly if not regularly monitored; which brings us to the fires, and my theory.
Inside the room in the chambers are dials, these could be used to control the Methane level; the control is a delicate mix of Methane and Oxygen. Too much Oxygen and you risk an explosion, too much Methane and you risk a flash fire which appears more deadly than it is unless you have a limitless Methane supply.
Firedamp, as it is known to miners, can be fatal, but not in this case as there is no structural damage to the walls, which makes me believe Methane caused the fire, not Firedamp. With a little more digging, no pun intended, I found out that the area got involved in a fire that ran for days in the late 70s.
When I was in serving in the photo trade in Germany, I witnessed a flash fire when some Meths caught alight in one of our processing cabins; the event was a trifle unnerving, but not life-threating.
Years later, I had a similar incident when I was working in the Bristol museum when a lighter I was filling for a friend caught fire in my hand. While he was close to panic, the light was amusing to me as the gas that caught fire had such a low flash point, all I felt was a coldness as it drew air across my hand.
On the other hand, I have witnessed several fires involving aircraft that were horrific and did leave people dead, or severely burned during my days in the Royal Air Force.
