Re: Boeing 737MAX Grounded Worldwide Q4 2019

Personally, I'm not at all confident this crew with the flu-addled pilot and incompetent co-pilot could operate a NG with a failed AoA sensor without a crash. Would you disallow a discussion of crew performance in a hypothetical RN ship disaster even if the ship itself had a serious design shortcom...

Re: Boom Overture? Evolutionary, Revolutionary, or Aviation dead end?

I don't see the reasoning behind such a statement. Why not no bus noise on land? Period? Or no children noisily playing?Period? That's because a single coast-to-coast flight would benefit a handful of people, while it would effectively disturb millions of people. Period. Every noise-generating acti...

AFAIK they had eyed some technically matching supersonic cruise missile engine from the US first that finally cannot be made available for civil uses.

They were clueless from the start. But who cares, if there's enough dumb money to be had. That's the Silicon Valley mindset.

Does Boom want those Rafale engines now? (SNECMA M88)

Due to export control constraints, military engines most probably won't be seen on civil supersonic designs.

Re: Boom Overture? Evolutionary, Revolutionary, or Aviation dead end?

There are still plenty of airlines, like JAL that have invested into Boom, offer more than 55 premium seats in at least some of their aircrafts. The average ticket price these premium passengers pay (keeping in mind all the upgraders and mile-users) would still be way below what would be needed to ...

No booms over land. Period. I don't see the reasoning behind such a statement. Why not no bus noise on land? Period? Or no children noisily playing?Period? That's because a single coast-to-coast flight would benefit a handful of people, while it would effectively disturb millions of people. Period.

Re: Boom Overture? Evolutionary, Revolutionary, or Aviation dead end?

Boom Overture? Evolutionary, Revolutionary, or Aviation dead end? My vote Evolutionary. My vote: Stillborn and doomed from the start, due to wrong top level aircraft requirements. More than anything it's going to rely on finding the engine it needs. Those manufacturers won't commit to essentially d...

Re: Should airline regulators consider grounding B737 MAX series

THEY grounded the plane because people were screaming GROUND IT Nobody screamed. It has barely made the general news here in Germany. In Today's paper there is a 3 sentence blob on the last page. Not much more reporting overall since Monday. 2..3 days of contemplation. that does look quite the &quo...

Re: Lockheed Martin Awarded New Supersonic Aircraft Project by NASA

Now I'm not saying it's technically impossible, but how many places will be screaming NIMBY and how many people will still say they are bothered by the very dull but still noticeable sonic booms they create? :checkmark: Plus, even though they claim to have optimized/"shaped" the sonic boo...

Re: Concorde's sonic boom over the Atlantic back in the day

I was just watching the second of the two youtube videos posted by Keesje above........I noticed that the creator of the video emphasizes that the concorde took off at very high speed and in the video it certainly seems to be going faster just before t/o, than most regular jets....question I have i...

Re: Concorde's sonic boom over the Atlantic back in the day

On a somewhat related note, if one was in a normal widebody cruising at .80 or greater, and the Concorde wizzed by at Mach 2, can anyone describe how fast that aircraft would have flown by the other aircraft? I know the Concorde would have been much higher, but just for conversation sake. You often...

Which is one of two reasons that I doubt that the tariff would have stood at all... Please tell me which US made product the CS-100 and CS-300 competes against. Damn this annoyed me. I've heard this like 10 times from various posters as an argument. You are 100% wrong. Airlines don't purchase based...
