The entire point of jet fuel is that it DOESN'T "blow up easily", though.

unlike gasoline, It actually takes quite a bit of effort to ignite avgas in it's liquid form because it's designed to be aerosolized before being ignited.

Avgas and jet fuel aren't the same thing. Avgas is leaded gasoline used in airplane engines. Jet fuel is specially formulated for use in turbines.

And... Is this post about 9/11?

[–] Adderbox76@lemmy.ca 3 points 3 days ago (1 children)

No one mentioned 9-11. I'm not sure what you're getting at.

[–] nednobbins@lemmy.zip 5 points 3 days ago (1 children)

I assume it's a reference to one of the 9/11 conspiracy theories.

The claim was that jet fuel doesn't burn at a high enough temperature to melt steel. Therefore a bunch of burning jet fuel alone wouldn't have been enough to collapse the towers. Therefore someone must have put something else there.

Even XKCD got in on the joke. https://xkcd.com/966/

You are nearly spot on: it isn't just the heat it will produce, but the lack of ignition due to the oxygen required for ignition.

You'd be surprised at how much things aerosolise when they hit a skyscraper at 500 mph.

[–] expletivedeleted@lemmy.zip 1 points 2 days ago

Not at all. Seen it with my own eyes. Seriously, the effect mirrors a controlled demolition.

[–] Andonyx@lemmy.world 2 points 3 days ago (2 children)

I thought Avgas was 100ll, not jet fuel?

[–] gastroglizzy@piefed.social 1 points 3 days ago

You're correct; the terms are not interchangeable.

[–] Adderbox76@lemmy.ca 1 points 3 days ago (1 children)

I can't remember the which is which. I just remember that Avgas and 100ll are the two types of aviation fuel. My brain doesn't have the ability to remember which is which. Which is probably why it's a good thing I'm not a pilot...

[–] gallopingsnail@lemmy.sdf.org 3 points 3 days ago

Aviation gasoline or avgas is 100LL (100 octane, low lead), and jet fuel is Jet-A.

Once years ago, I used a few mL of gasoline as a solvent to clean grease from a part. To dispose of it, I put it in a can and tossed a lit match in.

The liquid gasoline extinguished the flame. Even gasoline is hard to ignite.
