What do you mean by bigger? The A320 has a cabin width of 395cm vs 380cm for the 737, so it is more spacious.

Insulating CEOs and executive from failure is a good way to push them to take more risks, if that's what the board/shareholders want. The issue with the 737MAX is that Boeing was too risk-averse: they should have made a brand new

Why do you think they would be dead if they saw Cherenkov radiation? It's a matter of depth: if the radioactive material was deep in the pond, they should be fine. I could see the Cherenkov radiation (indeed blue and not green) when I

A billion dollar would be dirt cheap for a clean sheet design. The MAX program (including its engine) is estimated at $2B-3B. For a clean sheet successor a safe assumption would be 7 to 8 years to EIS and $15B in investment.

Air Caraibes goes 3-4-3 in its A350-900. That's very tight, as the A350 is really intended to be 3-3-3 in economy. https://www.seatguru.com/airlines/Air_Caraibes/Air_Caraibes_...

A330s and A330NEOs are usually 2-4-2, though sometimes 3-3-3 in the cheapest LCCs. A350s are usually 3-3-3 in economy, with the cheapest LCCs going 3-4-3.

The field of study is called Epigenetics [1]. I know practically nothing about it, but it seems that some of these alterations to the expression of DNA are not only persistent, but can also be inherited. Which is why some of these discoveri

Yes, I think it is, none of what I wrote should come as a surprise to anyone even casually reading news about Boeing/Airbus. Certainly not an analyst crunching numbers.

The Qantas Flight 72 incident was quite a bit different, as all AoA sensors were working correctly. The issue was due to corruption on one of the CPU exploiting these AoA sensors value [1]. Though you are entirely correct that there was a d

787 orders and deliveries are very nice, but the bread and butter of Boeing and Airbus remains the 737 and A320 families. As you say Boeing has 500 orders for 787 yet to deliver, but they most importantly have 4,500 of the 737 remaining to

Japanese economy is about 3.5 times bigger than that of Australia. I'm not sure what your point is. Economical measures are hard to interpret, but they can give an indication: Japan GDP/capita is standing at 48,920 USD, and Austra

People remember fondly of Snow Leopard 10.6.8, but the introduction of Snow Leopard 10.6.0 was very rough, certainly not bug free. Snow Leopard did change a lot of things under the hood (64-bit mostly, maybe Grand Central Dispatch). At the

Contrary to popular belief, quad engine planes are not inefficient [1], at least not in terms of fuel consumption (we are talking 1% to 2% difference). In terms of dispatch reliability however I think they are doing somewhat worse than twin

$100mm is the list price. Actual prices are decided by the market. I've read about $50mm for the 737-8, the baseline 737MAX model. That was of course before the MCAS disaster. My layman understanding is that actual prices would be arou

It seems that the EU could retaliate immediately, due to an old WTO win [1]. Though probably for a smaller amount, somewhere between $2.2bn and $5.0bn. And then of course there is the pending WTO final decision against Boeing/US expect

US tariffs are 2.5% on cars and 25% on light trucks, while in the EU it is 10% on both. Most vehicles (66% [1]) sold in the US fall under the light-truck category. What Trump has threatened to do is to impose a 25% tariff not only on cars,

Pedantic maybe, but the 10% is not the Trump tariff, but the EU tariff. As far as I know it predates Trump's election and various trade wars.

Be careful when comparing EU prices to US prices: EU prices always include sales tax (varies by country, but 20% in France and 19% in Germany), while US prices never include them. Assuming 10% tariffs and 20% sales taxes, that bumps the $35
