Gian, the above was referring to the stick on magnetic shields, which don't fully enclose the canister.
You don't need to fully enclose it to get it hot enough to cause the canister to bulge.
I know, getting eg 0.5 L of cold water to a temperature close to boiling with a screw on top stove and full wind screen will most likely not cause any trouble.
But then what if your can was in a black bag on a sunny day in a hot area? And you're tired from riding all day, have fired up the stove and whilst your supper comes closer you fix some gear and forget for just 15 min what the stove is doing... suddenly it becomes an issue.
The canister I blew was standing on an avalanche shovel in snow at an air temperature of well below freezing. I'm also guessing but have done dialectic in this case

I didn't say it couldn't or doesn't happen but given the design of gas canisters, the chances of it actually exploding are pretty slim.
Yes, an explosion is unlikely. First it'll bulge the bottom. Depending on where your stove is - mostly close by - there's quite the potential for a story as the liquid gas flame is pretty impressive. I've not seen the height it jumps, but given the force it takes, that too must be impressive. I think we can agree that for drama it doesn't need to explode.

warnings from those having survived
I think just a small percentage of the stupid ones are 1. unlucky to get the change to see it happen, 2. lucky enough to survive it and 3. eager to admit their stupidity.
And 4. land on this forum or others, where you finally come across.
I simply do not recommend using a wind screen that covers the stove and canister. Just as the cited statement in the opening post.
I much appreciate this discussion since Landslide surely has a better clue of the potential risks, can make his own decision and will keep an eye on the stove, be it with or without a wind screen.
P.s.: does any one have a photo of the discussed wind screen? Had a quick look through the BB shop but couldn't figure which one was meant.
