It's also worth noting that we've learned the hard way that many types of accidents take-out all four engines simultaneously-- like British Airways Flight 9 in 1982 which accidentally flew through a volcanic flume and lost all four engines.

The 777 is my favorite also, it's a beautiful well-designed and well-built plane with an almost unbelievable safety record. (Barring being sabotaged by the pilot, or being shot down by a surface-to-air missile, which are hardly things you can blame on the aircraft itself.)

Upvote from one triple 7 fan to another. I love those planes. The Heathrow flight 38 crash was the first hull loss in the history of the 777 program: not bad considering the first commercial flight was in 1995.

Still have not flown in a 787 as I mostly fly United and they don't have too many of them in the fleet yet. Ironically it's mostly 747s on the routes I regularly fly to Europe so I get to experience them regularly along with the odd A-380. (The latter a comfortable ride but just no poetry in the thing. It looks like a squashed frog.)

My fascination with the 777 lead me to a great documentary on Rolls Royce and jet engine manufacture: https://www.youtube.com/watch?v=VfomloUg2Gw.

Note that Rolls Royce faces stiff competition with chiefly General Electric as the engine supplier for the 777 line.
