because painting an entire neighborhood in flammable fluid isn't safe... if it doesn't catch fire it'll corrode everything it touches.

most planes can't dump fuel anymore. if it's a serious enough emergency you land overweight. If it's not then you fly long enough to burn it off and land below max landing weight.

When fuel is dumped, it's at high altitude where it just evaporates.

Short haul jets can't do it, but their max takeoff weight is around their max landing weight, so it's fine. For long haul, it's not the same.

It wouldn't have been in this case, is the point people are making.

This airplane was not at high altitude. It crashed right after taking off. It only ever climbed to a few hundred feet in the air.

Yes, I was refuting the generic "planes don't dump fuel" statement.

Are both opposing replies just wild speculation from two educated software engineers that don't actually know anything on the topic?

> most planes can't dump fuel anymore

This is true but irrelevant to this crash. Most commercial jets are smaller (A320, 737 etc) and can't dump fuel.

Long-haul jets like the 787 do have the capability.

If it’s HN, yes always.

No one overestimates themselves in other knowledge domains quite like software engineers... with the possible exception of medical doctors.

It won't corrode I don't think. It's just oil, it's not petrol like in small airplanes.
