Didn’t say it was exclusive to Boeing, just said Boeing had the certification.

[A.A. Cunningham]

Boeing had what’s called ETOPS

That's what you wrote giving the impression that ETOPS is exclusive to Boeing which it isn't.

You also wrote:

I believe only Boeing 767/777 are ok’d for o/s flights of over three hours.

and

They only use the four engine jobs on o/s flights of long duration.

and

says that it can go 180 minutes without engines to the nearest airport three hours away.

which are also incorrect.

Please explain how a 767/777 could fly 180 minutes without "engines"?
