You didn't light water on fire though.

You chemically altered it in a manner that is not the same as "lighting it on fire"

Yeah all that post needed was a connection between Delta's diversity hiring practices and their fuel dumping policies.



That is a stupid comment.

Go ahead and get yourself a doctor from the obvious lower reaches of his class, its all good.

Would you agree that at 1 atmosphere both liquid water and loquid jet fuel are similarly flammable?

Ambient temperature?

Sure.

Probably say combustible. I mean, we walk the edge on combustible/flammable for this purpose.

When I am headed towards the ground I would be concerned about the flammability and not the safety factor built in.

Why the frick is an airplane “dumping fuel”?!? Go frick yourselves, air industry. And wonder why the price of a plane ticket has gone up exponentially... it’s because apparently they’re throwing away the fricking fuel we as customers are paying for.

fricking dumb.

My point is that obviously jet fuel is combustible given the right conditions. However its not as readily flammable as many people think.

Close enough that I wouldn't smoke around it. More flammable than diesel, less than gasoline.

I would think the surfaces that reach 100 degrees in a crash would provide enough of a launchpad if given a source.

How different is jet A from regular kerosene aside from quality?

re: Delta flight dumps jet fuel on school playground
dumping the fuel was required to get down to the landing weight allowed by the design,,,,according to the linked article which described the plane losing an engine operation not long after takeoff

re: Delta flight dumps jet fuel on school playground
jet fuel is primarily a blend of kerosene and diesel with additives to make sure there is no free water present that was freeze at normal flying altitudes where the temperature may be 20 degrees below zero.

Maybe one of the OT pilots can chime in as to why an aircraft would need to perform a fuel dump in an emergency situation?


Many planes can't land safely at the weight they takeoff

Pretty much. Water limits vary depending on domestic or international.

Ok. Burn water.

Like I said, with enough pressure, fuel, and oxygen, anything burns.


So, turn the water into something else, then burn that. In this case, turn the water into hydrogen and oxygen, then burn the hydrogen. Got it.

Interestingly enough, burning is just oxidation, so when you burn the hydrogen you spent energy to get from the water, you get... water.

ETA: I'm not really this interested. I'm just busting balls.

re: Delta flight dumps jet fuel on school playground
I’m a pilot

I once siphoned jet fuel out of my airplane into my zippo so I could light a cigarette

Didn’t work.

Jet fuel isn’t flammable.

What role in making a jet engine function do you suppose jet fuel plays?

Here’s a hint.



What do you suppose caused this jet to explode on impact? Keep in mind this crash took place moments after impact when the jet’s fuel tank are full.

I mean, kerosene lamps are not a new invention.

That demostrates the beauty of kerosene's flammability.
