2019 has been a true _annus horribilis_ for Boeing.

Well, engin failures are not exactly the rarest of occurrences. It's just that given the context, every stories about Boeing will gain quite a bit of traction. It's probably deserved given how bad the company have messed-up, but let not overreact.

Engine failures are not rare, true, but engine failures pelting populated areas with hot shrapnel are not that common.

This ended well, fortunately. But that must have been pretty scary. A 787 that is out one engine will put extra load on the remaining engine, if that one has gone through a similar life as the one that just dropped bits all over the place I'd not wager on the remaining one being as safe as when it was last inspected. That's a lot of eggs in one basket. And they don't glide particularly well either, though there are s…

That's a lot of eggs in one basket. That's why there are restrictions on which RR engines can be put in a 787 as well as a reduction in the ETOPS certification. There've…

Wow is this really how the industry views it? The notion of having one "less fixed" engine on a twin engine commercial jet aircraft is ok, so long as the other engine is the more fixed version? Sounds incredibly risky.

For such a critical component, I figured they would adopt the military position: "2 is one... one is none".

Not mentioned in OP's comment.

Is there a point you wanted to make or is this a non-sequitur?

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

Depends where they land. Rain on a crowded playground and that's catastrophic for many reasons.

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.

Being Rome and all... I could see a bunch of people with any sort of dings in their cars or windshield chips making claims in the near future :-)

Being an Italian born in Rome, I find your comment implying bad faith offensive.

"melted off" sounds a bit improbable, actual photos of the shards:

they don't seem melted, rather broken/fractured.

> And they don't glide particularly well either Nonsense! Modern airlines glide exceptionally well. For example a 787 has a glide ratio of over 20:1 ! http://www.lissys.demon.co.uk/samp1/ https://seekingalpha.com/article/2494925-boeing-the-airbus-a...

All a moot point when you're over the ocean :)

That's a Sully comment.

>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.

Sold to vickers in 1980.

The 70s rollers were of their era... All cars were unreliable then!
