It can 1) save a diversion and 2) save a lot of bad press for the airline. Would it really save a diversion? I'd think that they'd still want the person off the plane and under real medical care. Depends. If they're flying JFK-SFO and the issue occurs while they are at FL 350 just west of SMF, it c...Jump to post
In any event, I see no way that the MAX program returns an overall program profit. Same as the 787. So Boeing will have its cash cow - 737 - never make a profit along with the 787 which requires a paper write off, but Chpt.11 is so far outside the realm of possibility that when suggested as a possi...Jump to post
Seriously, I can’t see any circumstances where MAX never flies again. Absolute worst case I can see is a complete recertification as a non-NG 737 variant. With the backlog it’s got, there’s no way Boeing can just shrug their shoulders and not get TPFKAM* back in the air. While I agree a "never...Jump to post
Many seem to think that Narcan is only for "addicts". :checkmark: :thumbsup: The worst fake argument is "If it would save just one life". I can't say whether the people who came up with this idea at DL had genuinely honorable motives or not, but even if they are nothing but cold...Jump to post

It's interesting that this issue only affects the A321neo and not the A320neo (so far at least). One would think that the A321 has more pitch authority than the A320 given its greater length than the latter, so it would be less sensitive to any pitch anomaly. The A321 has a longer body than the A32...Jump to post
Eastbound, maybe. But westbound is going to require a fuel stop at ANC. This is a 788 route. But where is the demand for a 788 from SFO to CTS going to come from?Jump to post

KE, LH and BA all operate regularly scheduled pax 747 operations here to N. America along with others. (B744s and B748s) What about this one? Technically a passenger jetliner. 5570755 Technically not a Boeing 747. It's a VC-25 and it is not a passenger airliner, but rather an airforce aircraft.Jump to post

Only if Section 41 (cockpit) could be grafted onto a narrower fuselage, but that's about it. The 767 Section 41 cockpit was used on the 777.

That flap looks astonishingly intact, considering it fell from considerable hight.

As orders begin to slow and technology advances, Boeing will probably look at upgrading the engines and introducing a 787NG, similar to what was done with the 777 and the GE-90-110/115 re-engine. We could also see a 787-F variant introduced along the way. But the 787 is a solid design will sell in i...Jump to post

I have a question about this flight. If you look at the track on FlightAware (https://flightaware.com/live/flight/VIR138/history/20190704/2310Z/KJFK/KBOS), they began their descent just about over the CT/MA border and descended quickly, but then flew past BOS, did a loop, and then landed.

I'm in Santa Barbara right now and we felt it while sitting in a Yogurtland.

Almost the entire Asian continent lies north of the equator, which means that all great circle routes from the USA will tend north, so a southern city like Dallas is at a disadvantage because it is further from most of Asia than Chicago.

Suppose it costs an airline 13¢ per mile to fly a passenger. It might cost them 11.5¢ per mile to fly that same seat empty.

I'm shocked that they are still building 40 frames a month in Renton. It shows loyalty to their workers but at some point they'll have to stop.

That first pic is stunning, looks like it has afterburners. Never seen anything like that glow from behind the engines on any commercial airliner turbofan before.

Boeing narrowbodies (737/757). I'm tired of my shoulders being crammed against my neighbor's. It is different on the A320 family.
And also, I'm not a huge A380 fan. Not only Embarcation/disembarcation take a while, but also the walls are so thick that you can barely see out the window.
However, waves in and of themselves do not cause drag.. Waves generated by the ship carry energy away that is provided by the movement of the ship. So they do cause drag. You can get into some strange cause/effect loops in fluid dynamics, but a wave traveling away from the ship cannot act directly ...Jump to post

Today's cruise ships are designed with hull shapes that create secondary waves that self cancel the primary wake. The result is a relatively tiny wake that would otherwise be huge and a large disruption to other ships.

I think though that the origin of the rattling are not the shockwaves.

Back to fuel efficiency. Using the the physics principle that ke=½ m*v^2. Not a good equation in this case.
