A deflagration rather than a detonation.

One way to get rid of those pesky labour voters, eh?

Tory Scum? That'll show em.

The adaptation of proximity fuses to artillery shells intended for ground targets was devastating: airbursts above trench level took out personnel in those trenches.

Airburst bombs are also handy to take out above ground structures.

Ronan Point?

"At approximately 5:45 am on 16 May 1968, resident Ivy Hodge went into her kitchen in flat 90, a corner flat on the 18th floor of the building, and lit a match to light the gas stove for a cup of tea. The match sparked a gas explosion that blew out the load-bearing flank walls, which had been supporting the four flats above. It is believed that the weaknesses were in the joints connecting the vertical walls to the floor slabs. The flank walls fell away, leaving the floors above unsupported and causing the progressive collapse of the south-east corner of the building.

The building had just opened, and three of the four flats immediately above Hodge's were unoccupied. Four of the 260 residents died immediately and seventeen were injured, including a young mother who was stranded on a narrow ledge when the rest of her living room disappeared. Hodge survived, having been blown across the room and clear of the collapsing walls by the explosion ? as did her gas stove, which she took to her new address"

Fuel air bombs are extremely powerful.

first one was an old kooncil hoose with an unvented under building with a gas leak into it the tenants opened the back door and switched on the light and the WC pan ended up half way doon the garden.....second was a new kitchen fitted by Billy the joiner who relocated the cooker bayonet to the back of the new kitchen cabinet BANG mid terrace wiped out along with two cars .... got pictures somewhere if interested

We had an incident where a fellow ham blew up his house he was messing about with a paraffin blow torch in front of a fire and left it sitting and unknown to him it was pressurised and emitting vapour which eventually blew up the living room...the polis thought he was a terrorist and was messing about with explosives...

won't have been timber framed that is for sure....

wonder what they were digging up out the back garden ? ...

Probably more to do with where in the house it was. The problems with gas of course is that it is the air/gas proportions that matter, also if the leak has been going on for a while then the fireball propagates and does far more damage. I'm not a great fan of gas myself. Brian

I don't think they would report as gas if it was not, it would be too hard to do without leaving a trace. It does often worry me though that sometimes buildings strategically placed that are in the way of a possible development tend to burn down or blow up. Brian

Its far less easy to keep hydrogen in a place and get an explosive mixture though. Brian

I particularly liked that final point, it has a touch of the Lord Denning about it!

1968 would have been coal gas.

You'll find throughout industry, they are happy enough to have natural gas on site and the Engineering designs and protections are not too onerous, but it all becomes a whole lot harder once Hydrogen is present!

True. The frame would probably have survived intact.

That happened near here a few years back. Disused shop downstairs, flat upstairs with sitting tenant. Shop caught fire in the night. The owner of the site now has a splendid new building there.

What's not to like about natural gas ?

"A woman in a neighbouring home was also injured by the explosion that damaged 20 other homes. An 11-year-old girl suffered a broken collarbone. "

That tells you there was a pretty good shock wave.

I've seen several pictures similar to that. One of the others, nine houses were damaged. Sometimes the house next door to the splody one, has to be demolished because of structural damage.

Paul

I had to demolish three homes with all their possessions in them .....
