First comment not successful. This was in my morning news feed. https://www.flightglobal.com/news/articles/a321neo-operators-alerted-over-excessive-pitch-ano-459718/

This was of interest in my news feed. The A321NEO, like the 737 Max, has an engine change from the original design. NEO = New Engine Option. Fortunately, there have been no accidents reported. https://www.flightglobal.com/news/articles/a321neo-operators-alerted-over-excessive-pitch-ano-459718/

The proper way to frame the F-35 program is that it is 3 nearly separate aircraft, with perhaps 20% commonality, mostly around the cockpit. Hard to believe that any one in Congress was fooled into thinking it was just different service markings on each model. That being said, it was still accquisition malpractice. There will be about 500 in service by the end of 2019. Way too late to shut the barn door. I am going to wait to hear the pilot community speak before I render a thumbs up or down.

OK, I thought this was great and then you got to a John Hiatt reference. You Win!!
Have flown nothing but Cessna but but I am with him!
I hope his medical coverage inclures the surgical removal of one or more feet from a mouth.
As MCAS is software, I don't believe there is a way to switch it off. The option is to turn the electric motor off on the screwjack mechanism in the stabilizer system. Then you have to trim the horizontal stabilizer by hand using the manual trim system.
If I have this correctly, the manual trim wheel is a left over from the 1967 design process. The actual trim system, the one MCAS took over, is the powerful electric motor/screwjack system that moves both horizontal stabilizers in order to set pitch. In manual mode the pilots control that system with a thumb switch on the yoke. In an A320, there is a similar primary trim system, but no back up manual trim system because, unlike the boosted cable controls of the 737, it is fly by wire. So the 737 can be considered to have an extra margin of safety that its Airbus counterparts do not have.
One large point is service after sale. Boeing is making a dedicated, sustained push to expand its MRO business. They also have an enormously efficient production process. They may make far money on sustaining the jets than producing them.
Yes. If I am awake at 11:30 PM tonight (a big if), I should be able to see the lift off to the South.

737 Max & Boeing Update The Paris Airshow has come and gone. Airbus did very well, particularly with the new A321 XLR, signing up an impressive array of customers. This is why this is cool for passengers. Your correspondent lives... Continue reading

One point. It is not the knowledge that is important. That has been around for 75 years. It is the material, the fissile material, that is the crux of the efforts to demonize Iran.
Excellent summary.
Thank you, TTG. That would be a good subject indeed. Will try to oblige this coming week.
Should be pretty soon on the untethered test. If it goes well, they are aiming at 16,000 feet. From Teslerati. "Longer tests demand that SpaceX begins expanding the known performance envelope of its full-scale Raptor engine. Towards that end, longer-duration tests would need to be done at the company’s McGregor, TX development facilities to reduce risk, tests that Musk confirmed are already well underway. A recent Raptor static fire reportedly lasted no less than 40 seconds, more than enough time for a single-engine Starhopper to significantly expand both the maximum altitude and velocity of future hop tests. In support of the upcoming Starhopper test campaign, significant construction work is also ongoing at SpaceX’s Boca Chica test and development facilities." In the YouTube video by Everyday Astronaut, he has a table with the thrust to weight ratios of a series of engines and other stats, including specific impulse.

In the near future we may be witness to an advancement in the use of materials that harken back to the earlier days of the US space program. And a rocket constructed of one of the early materials, stainless steel,... Continue reading

KH, the F-4 was actually developed by the Navy as a fleet defender. Able to carry a big radar, plenty of gas and Sparrow missiles to kill Russian maritime aircraft. It was pressed into service as a multi-role fighter-bomber and they built a ton of them. As you say, it was not designed for air superiority as it had been optimized for beyond visual range intercept. The F-104 as a NATO aircraft was a bad decision, aided by liberal bribes. It was designed as a point interceptor and pressed into a role it wasn't suited for. EMALS was designed to reduced manpower, as well as avoid the need to generate steam and the piping associated with it. Incomprehensible to me why the setting up a single point of failure. These ships are supposed to operate with battle damage.

KH, this is a good summary article of where the F-35 program is right now. Yes, it's positive but I find it factual. https://www.ainonline.com/aviation-news/defense/2019-06-17/f-35-looks-future

KH, but why was EMALS designed and installed? They have to get it right, of course, but clumsy program management doesn't equal technical incompetence, IMO. On the F-35, the program appears to be on track to have delivered 500 aircraft by years end. Again, program selling and execution was awful but the 3 different airplanes the program produced appear to be delivering on their intent. One underestimated issue with this aircarft is that each model has no more than 25% in common with the other. They sold a one model for all but built three nearly unique jets.

I have read Zubrin's book and David Brin is a favorite. I would agree that Mars is better positioned for harvesting asteroid resources. Saying that, I believe the proper arguments still stand. A consortium of nations could undertake the exploration, after a long effort of R&D. We appear to not truly know how long a human can survive on Mars and stay helthy. IMO, we have a huge number of learnings to accomplish before it begins to make sense to try.

JJ, I was employed by Martin Marietta, at MAF, on the External Tank project. I had left by the time of the loss of Columbia. Your comments about the political football being disastrous for NASA are completely on point. It never got worse than "Faster, Cheaper, Better" which produced a cockeyed Hubble telescope and a lost mission to Mars.

Teflon was invented in 1938 by Roy Plunkett. It's invention by NASA is another canard. Please read through some of the links. You may still disagree about the value project but you will be better informed.

You mean't a Saturn 5, not an Atlas. There were more than one left over. We had one as a gate display at my workplace, the first stage at least. And, soley? Please be serious. Look up Skylab in Wiki and get back to us on soley.
