I would say, as european, that all this storm of shit is good news for Airbus, but I hop on Boeing planes too, and I think competition is good news.

A380 is an amazing business case. Ask anyone who has flown on one what their favourite commercial plane is and I would bet the majority will say it's the A380. Despite that it was still a commercial failure.
Exactly. A good airplane isnt enough. The manufacturer has to follow the market, not expect that thier new aircraft will create that market.
You need to plan ahead.

#74There have been 894 deliveries through September 2019. So far only one incident involving the uncontained failure of a Rolls Royce Trent 1000 engine. There have been no complete losses.

Randomizes destructive testing is a perfectly fine and established procedure.
Yes, I know, but is this the required procedure for this part? It's definitely more expensive than some visual or electrical inspections. That's why I said I'm reluctant that this is the procedure.
Please stick to working on front end UI. You scare me.

Actually, there as an argument that it is not good for Airbus at all because it will risk the stability of duopoly between Boing and Airbus. The idea is that now Boing will be forced to actually invest tens of billions in new aircraft design, forcing Airbus to do the same instead of milking the current designs for as long as possible. Also, apparently the aircraft manufacturing is not a very flexible business and Air…
I like thinking about this in a sort of hypothetical Sparta. Sparta had two kings from two different royal lines.
Suppose you're one of two kings, and the other royal line experiences some sort of dynastic hiccup. This inevitably happens to everyone.
A popular strategy throughout history is to capitalize on that hiccup by exterminating the existing royal line, or at least driving them out of power so you can take it yourself. As a king, you are ideally positioned to do this. Maybe you can take both thrones and be the double-king. Maybe you can put your cousin on the second throne. Maybe you can put a flunky on the second throne. Maybe you can get rid of the second throne, leaving yourself as sole king.
But once you do that, a precedent has been set. Your line will eventually stumble too, and it is likely to suffer whatever fate befell the other line the first time. Another strategy you have, back when the rival line first shows weakness, is to stake everything you have on your commitment to upholding the Spartan way of life as expressed in the dual kingship. Give rousing speeches on how unthinkable it would be for anything about the current setup to change. Throw all your considerable resources into supporting the king on the other throne, no matter how weak his position might look.
If that sticks, the other line is likely to remember that you were there when they needed you. But even more than that, you've just established that the dual kingship, and the two families who fill it, are an integral part of the culture, never to be questioned. That tradition may ultimately prove more helpful to you than any personal support. And it has such obvious benefits to the other royal line that, going forward, they will likely support it just as strongly as you do.
On this analogy, the problem with disturbing the Airbus / Boeing duopoly isn't that Boeing might start to compete with Airbus, provoking an arms race. The bigger problem is that (as you mention) some other company might start thinking they can make airplanes too, and who knows what could happen then.

After the demise of the a380 project i doubt airbus will ever think again that the aircraft can sell themselves.
A380 is an amazing business case. Ask anyone who has flown on one what their favourite commercial plane is and I would bet the majority will say it's the A380. Despite that it was still a commercial failure.

Judge the content not the source.
I don’t know if this is entirely correct for all circumstances. It’s possible that a source known for complete fabrication of facts may display a very unbiased looking content; it’s just that none of the content is real. Like The Onion. It’s also important to note sources for their biases so you may be able to discern what facts are being intentionally left out of an otherwise comprehensive content. Perhaps some mix…
I remember in particular a piece Malcolm Gladwell wrote on football and head injuries. ( https://www.newyorker.com/magazine/2009/10/19/offensive-play )
I am willing to believe that football causes head injuries for other reasons. I am generally against this. So I let a few people know about the piece. I'd also give them a warning: Malcolm Gladwell generally doesn't know what he's talking about, and it's a bad idea to pay attention to what he says. That said, this is an interesting piece by Malcolm Gladwell.
I know this is the wrong thing to do. You can use Malcolm Gladwell's piece to make arguments against football because every argument is more persuasive when Malcolm Gladwell makes it. That's his only skill, but it is very highly developed. The problem is that that's a terrible reason to believe an argument. The Malcolm-Gladwell-sounds-convincing argument can prove anything at all, as long as Malcolm Gladwell wants it to. The correct thing to do as the person being argued at is to completely dismiss whatever he says, because it will sound convincing regardless of whether it's true.

What happened there: wrong kind of oil was used in elevator and it went unnoticed because maintenance guides did not require any inspections of affected parts. Wrong oil caused delays in sensor triggering, which led to primary computers shutting down, believing that there was a problem with elevator.
Backup computers didn't detect gear compression correctly when the aicraft bounced on the runway (one computer believed it was on the ground, the other that it was airborne) and also shut down and locked the elevator in neutral (zero) position as a safety measure.
This happened during a touch-and-go landing on a training flight. The A320 touched down, bounced, elevator got locked, the aircraft climbed a bit, then fell down on the runway scraping and damaging engines (due to loss of control), then took off again (not enough runway left for stopping) and was now flying with no elevator and with engines about to shut down. It's a miracle that pilots managed to turn around and land safely.
In 1993, Lufthansa A320 crashed under similar conditions: landed in poor conditions, computers didn't think it was on the ground and didn't allow braking until it was too late https://en.wikipedia.org/wiki/Lufthansa_Flight_2904
