And now the Boeing 777...

coppercone2:
there might be titanium keeping it burning but thats not titanium burning as I know it, when you put it on a grinding wheel it makes a bright white spark stream (impress the neighbors and light the trash on fire)

That looks like hydrocarbon fire to me. if there is titanium burning in there it would keep the fuel burning like a pilot light on a stove. I never saw non powder titanium burn but I imagine it looks like magnesium, you don't get any kind of bushy plasma from it, its going to glow white hot and emit alot of grey smoke. I don't know how well those engines turn off or how much is left in the line after turn off or if there are lubricants and stuff there that also burn eventually

To me, the fire is quite subdued - and is diminishing all during that clip.  Could it be there was still fuel in the lines between the shut-off and the engine?  Could it be other oil lines or hydraulic lines feeding it?



People really need to stop hypothesising and just wait for those who actually know something have a look and tell us.

Yeah, only 777's with the Pratt & Whitney engine are grounded.

So you're saying it is somehow the 777's fault?

You would be totally comfortable getting on an Airbus with PW4000s, or a 747?   :o

It's a Pratt & Whitney Dependable Engine fitted on that thing, and serviced by UAL's maintenance team.

It's the optics of it.

Well, yeah, especially with the current narrative of "Boeing = Bad."


--- Quote ---Another PW4000 series on a 747 shed its guts over the Netherlands the same day.. and another United flight (a 737 this time, not a P&W engine) had an engine failure, also the same day. Most aren't going to care about what engine it was - three more Boeings went bad all in one day.

So you'd also be another person who would be comfortable right now getting on an Airbus with PW4000 engines because it is obviously Boeing's fault that the P&W engine failed catastrophically on a UAL flight?    ::)

You got that the wrong way around.

777's with the Pratt & Whitney engine are grounded. All 777's with other engines haven't been grounded.
