Mildly Interesting

This is for strictly mildly interesting material. If it's too interesting, it doesn't belong. If it's not interesting, it doesn't belong.

This is obviously an objective criteria, so the mods are always right. Or maybe mildly right? Ahh.. what do we know?

Just post some stuff and don't spam.

Most bridges here do, and often when one needs to be demolished and rebuilt, the military blows it up just for practice.

Edit: Source for the sceptics

The deep demolition, which became a central element in Finnish post-war demolition tactics, and especially the development of readiness to counter surprise attacks that emerged as a threat scenario in the 1960s, received significant support immediately after the wars. The decision concerning structural demolition preparations for bridges was made on January 15, 1946. These preparations meant building charge wells, charge chambers, charge pipes, and charge hooks. Authorities responsible for constructing bridges were required to include the aforementioned structures in their plans, which significantly improved the readiness to destroy the bridges.

If it was not possible to place the charge space inside the abutment or pier, charge hooks could be embedded in the supports during the casting phase, to which the charges could then be attached.

I'm not opposed in any way. I just don't personally believe it. I think OP is full of bullshit, as a lot of people are.

I couldn't even recall the amount of "facts" people throw around and then get super mad when someone points out their "facts" don't make sense at all.

These hooks were on every single bridge pillar I saw

Yep. All around Finland.

All the talk of the defensive strategies (that we've had since the Winter War) only speak of these being applied to the eastern part of Finland. And you can even look at a map to see the roads round there mainly going in the same way and there not being lots of roads joining them. It's all part of their defensive strategy. Shutting off infra from where an attack would come from.

But what is the fucking point in supposedly being ready to blow up a bridge in Forssa? Tell me the strategic advantage any enemy would have with it?

I'm really tempted to just email Destia and ask for a confirmation but I feel like asking stuff like that might sound a bit suspicious so I hesitate.

Go ahead if it bothers you so but yeah unless they confirm it or you make even a remotely rational explanation to them, I'm not buying it. Why does me not personally believing in something bug you so? If you need No proof to assert it, I need No proof to assert the negative of the same assertion.

Keskeisen aseman suomalaisessa sodanjälkeisessä suluttamistaktiikassa saanut syvä suluttaminen ja etenkin 1960-luvulla uhkakuviin nousseen yllätyshyökkäyksen torjuntavalmiuden kehittäminen saivat merkittävän tuen heti sotien jälkeen. Siltoja koskeva päätös rakenteellisista suluttamisvalmisteluista tehtiin 15.1.1946. Niillä tarkoitettiin panoskaivojen, panoskomeroiden, panosputkien ja panoskoukkujen rakentamista. Siltoja rakennuttavat viranomaiset velvoitettiin sisällyttämään suunnitelmiin edellä mainitut rakenteet, joiden ansiosta siltojen hävittämisvalmius parani oleellisesti.

Mikäli panostilan sijoittaminen maa- tai välituen sisälle ei ollut mahdollista, tukiin voitiin valamisvaiheessa sijoittaa panoskoukkuja, joihin panokset voitiin kiinnittää.
