So why did they not tell the passengers until they were at TOD into Kona that they had lost an engine? Surely all of our passengers nowadays are fully aware of the fact that they are mostly floating around above the world's oceans on just two engines to start with? They would simply have ordered another gin and tonic and re-set their watches!
I am sure they would have been more than happy and reassured to know that just one of Mr Pratt & Whitney's products was keeping their feet dry and would hopefully continue to do so for the next 3 hours or so.
I am bloody grateful that I gave up this sort of crap when I was on the DC-10.
