not to hijack thread...Hawaii planning

[svcta]

I didn't want to hijack the guy's thread so here is my question:

Forgive me, I'm new at planning GA flights over water and I have a question.....

Regarding the X that landed in San Fran and then to San Jose.....1800 pounds(see other thread.....Citation X to hawaii).

What would have been the arrival fuel assuming an engine failure at the halfway point-- After the driftdown and subsequent fuel burn at the new altitude?

This isn't a rhetorical question aimed at you, I just really want to know.
Hawaii is the longest ETOPS(sorry for the airline ref.) segment in the world, and being new to the corporate world I get the impression that some operators do this with impunity. I'm trying to learn(this isn't an "airline vs. corporate" thing...I like it more here)

The biggest problem with making the west coast to HI crossing isn't losing an engine and having enough fuel: it's losing pressurization. Having a pressurization problem is far more likely than losing an engine statistically speaking and would force you to a lower altitude thereby burning more fuel and possibly coming up short (AKA Wet Footprint). Corporate jets of all types and ages have been coming and going to Hawaii without incident for years. Nevertheless, if you have any influence on the boss' purchasing decisions, tell him to buy more range than he can afford and then figure out a way to pay for it...

That's really the question I was looking for an answer to: It really is a matter of sort of throwing caution to the wind(?).
