This really doesn't make me feel very confident about getting on a 787 for a 14 hour flight next week.

If it has GEnx engines you have little to worry about. The easiest way to tell the difference is the GE has metal leading edges on the fan. The Trent fans are all cfrp.

CFRP = Carbon Fibre Reinforced Polymer.

Who is responsible from a liability perspective: Boeing, Rolls Royce, or Norwegian?

I don't know if there are special rules for air traffic. But generally, the immediate operator (i. e. the airline in this case) would be responsible. If any of the manufacturers (or possibly a maintenance contractor) were to be responsible, the airline would simply be able to recover whatever damages they had to pay from them.

Can you tell this when booking your tickets? It isn't a detail I've seen using most travel websites or even an airline's own app.

tbf the Trent 1000 is one of two engine options on the 787; more have GE engines fitted so on the balance of probability your aircraft has a completely different engine anyway. The ability to fly for extended distances on a single engine is something modern long haul aircraft are designed for and pilots trained for, and even if it's a RR-engined aircraft you're probably more likely to have engine issues with birdstri…

It's an El Al flight, and their entire fleet of 787-9s use RR Trent 1000 engines.

I'm exaggerating a bit about my concern. I know the statistics on modern aviation safety, even with Boeing's, uh, recent track record on such things.

Frankly, in the grand scheme of things, I'm more concerned about my safety driving in Tel Aviv than I am about my flight getting there ;)

Small shards (in great numbers) that according to a witness on the ground were burning or very hot sounds a lot like (pieces of) blades from the turbine or stator/guide vanes. In both cases it's a very significant engine failure.

Given that the aircraft itself seems otherwise undamaged, and people on the ground reported it 'rained' metal shards, I'd say these parts melted off the turbine and fell out. Significant but not catastrophic.

> significant but not catastrophic

So... not great but not horrifying?

On the contrary, it makes me more confident.

Engine parts melt and fall off, and the plane doesn't seem disturbed. Awesome engineering!

Last minute airplane swaps are not uncommon, so such a feature doesn't necessarily help.

Is this the same issue that has plagued the Trent 1000 since the beginning or is it something different? It says the plane is 5.5 years but I guess that doesn’t say whether the engine had been modernized.

On the bright side, Rolls seem to have sorted out most issues from the 1000 in their newer engine the XWB.

https://www.forbes.com/sites/davidnikel/2019/08/12/norwegian... The plane in question was a 5.5-year-old Boeing 787-8 with the registration LN-LND. The parts are believed to have come from the left engine, a Rolls-Royce Trent 1000, a model that has been plagued with problems.

> I'm reminded of all the jokes Jeremy Clarkson makes at Rolls Royce's expense... Rolls-Royce Holdings only makes aero engines, the cars are made by BMW.

>the cars are made by BMW.

as of 1998.

Most of Clarksons' jokes are in reference to the 70s and 80s era of Rolls Royce -- which is known among auto enthusiasts as one of the least reliable group of cars to have ever existed.
