[TT1] As I said previously, airliner hull losses ALWAYS have tons of blame to pass around, it is never a singular point of failure.
As the investigation continues into the causes of the Mar. 10 Ethiopian Airlines Boeing 737 MAX accident, sources close to the probe say flight data recorder (FDR) data firmly supports the supposition that the aircraft’s left angle-of-attack (AOA) sensor vane detached seconds after take-off and that, contrary to statements from the airline, suggests the crew did not follow all the steps for the correct procedure for a runaway stabilizer.
…
The source indicates the crew appeared to be overwhelmed and, in a high workload environment, may not have followed the recommended procedures for re-trimming. Boeing’s stabilizer runaway checklist’s second step directs pilots to “control aircraft pitch attitude manually with control column and main electric trim as needed,” according to one U.S. airline’s manual reviewed by Aviation Week. If the runaway condition persists, the cut-out switches should be toggled, the checklist says.
[TT2] Creating water that never freezes. I love it when we cause materials and chemicals to behave in ways that violate those general understandings of how physics works. I’m just waiting for Physics to get sick of all our non-standard play, pick up all their toys, and stomp off in a huff.
[TT3] SABRE takes another step forward.
[TT4] A concrete band-aid. Additionally, we can use bacteria to ward off potholes. And this one is exactly where we don’t need it to be.
[TT5] Beating cancer at it’s own game by hijacking a tumor to produce an immune response to destroy the cancer.
[TT6] I’m not terribly interested in the architecture of public buildings, except libraries, since I think of those as the places where the public is best served by it’s government. I love the Beaverton, OR library, and even the downtown Portland library. Here in AZ, the Arabian Branch library is very interesting as well. I still don’t like the Seattle PL, though.
[TT7] Ford took a look at the emissions of electric flying cars versus ground based electric and internal combustion vehicles, and guess what? Unless you are traveling less than 22 miles, you should fly.
[TT8] Well, I’ll sleep easier knowing that the dreamless sleeper is actually dead and fossilized.
[TT9] So, it’s not about vaccines, but rather who is adequately full of… ?
[TT10] I do wonder how soon before we can print fully functioning kidneys and the like (I expect things like Livers will be quite a ways off).
[TT11] New life for an older style of containing fusion plasma? I do like that they are taking a “Cautiously optimistic” approach to this. Always a good idea when playing with super-heated plasma.
[TT12] An industrial robot that has a learning AI, and kinda looks like something from a Hollywood movie (didn’t I see this in Upgrade)?
[TT13] Stratolaunch has launched, and flown, and landed in one piece.
[TT14] What NASA plans on spending our money on in the near future. Note the new spacesuit. Also note how many projects are looking at very small tech.
[TT15] Wind power, without the spinning blades. Although man, you hear about noise complaints now, just wait until your wind power sounds like a kazoo. Gonna need to combine it with some of these.

Related to TT01 – Vox does not disappoint. Nothing said in here is incorrect, but the music, and what is not talked about speaks volumes about the reporters intention.Report
[TT7] I keep wondering these days when the talk turns to flying cars about air traffic. How do we regulate this airspace? How do we cope with congestion? Will we require a pilot’s license to fly a flying car? The airlanes from SF to San Jose are already pretty crowded. And for a good portion of them, you can’t go higher because you will interfere with the restricted approaches to SFO and SJC.
I mean, yeah, the technology seems cool, but can we actually make better use of it than we do a helicopter? Apparently the fuel use profile is encouraging, actually better than a shuttle bus? Even an electric shuttle bus?Report
Airspace crowding for airliners is very different from airspace crowding for small VTOL craft. VTOL craft will need more separation that a car on the road, but considerably less than airliners in approach and departure lanes. And small VTOLs will never operate in the cruise lanes of airliners. I wouldn’t be surprised if the FAA gave such things a hard ceiling of 2000′ (maybe 3000′ for larger vehicles?) and severely restricted their operation around airports.
As for piloting, that is the kicker. These will have to be largely auto-piloted. How that is going to work, and what kind of traffic control will be employed… yeah, that’s got a ways to go.
As an aside, if such VTOLs became popular, I’d expect we’d see the decline and closure of a great many small airstrips. The ones that are currently kept alive through fees on air travel because it’s politically expedient to do so (or such airstrips would be re-purposed into recharge way-stations).Report
I wouldn’t be surprised if the FAA gave such things a hard ceiling of 2000′…
How loud are these things going to be? My city’s municipal code sets decibel limits on the amount of noise that can be created in residential areas. (The police do literally respond to some noise complaints with a decibel meter and then issue a citation.) What’s the aggregate noise level going to be for a steady stream of VTOLs flying overhead at something less than 2,000 ft?Report
Depends on the design. Put the props in ducts, and they are pretty quiet at a distance, since all the noise of a prop is at the blade tip.
If they become popular, you can employ whisper quiet prop and ducting designs (they are more expensive, which is why none of the early designs or prototypes use them).Report
It’s a lot easier to regulate when everything is a drone that operates under central control.
People talk about “flying cars” like they’ll get in and operate it entirely themselves, the way we run automobiles, and it’s just not gonna be like that.Report
The thing I’ve wondered about flying cars is how traffic might be managed. If we’re confining people to a set number of clearly marked routes, then you’re going to get traffic jams. If you’re not confining people to a set number of clearly marked routes. You’re going to get lots of accidents. Keeling eyes on side mirrors and blindspots is one thing. Looking out for traffic from up and down as well? I don’t see this going well at all. Being the only one up in the air is cool. Having 9 999 other maniacs up there with you is an absolute nightmare.Report

[TT6] I recently had a few hours to wait downtown in Calgary, so I went to the library. It is truly amazing. I stepped in the front door and stopped, wide-eyed. I pulled out my phone, took photos, and then looked over to see other people who’d just come in the building, also wide-eyed and photographing.
If I lived or worked near downtown Calgary, I’d sure spend a lot of time there. Our downtown library here in Edmonton is also being extensively rebuilt, and I look forward to the finished product. I doubt it’ll win any architecture awards, but I think it’ll be pretty cool.Report
Now you make me wish I’d visited the library when I was in Calgary some years ago.Report
The library that won the architecture award is under a year old. The old library was a totally unremarkable beige cube of a building. Generic six or so storey building that will probably become offices or condos now. Pleasant enough, because library, but nothing to go out of one’s way to see.
I didn’t actually know there was a new library, and had just meant to go to the library as a place where I could sit down and read for a few hours before catching my bus, since it was cold enough I didn’t feel like going for a walk. Getting to see this beautiful , airy, inviting secular cathedral was a total surprise.Report
Damn…
(Looks up customer lists, sees if I can find any justification for a work trip to Calgary…)Report
[TT7] is a pretty weird way to compare.
I mean, to get the VTOL to come out looking better, they had to compare the emissions per passenger-kilometer for 4 occupants in a VTOL vs 1.54 occupants in a car.
If you were going to drive somewhere alone, and want to reduce emissions by even more than taking a fully occupied VTOL, car-pool in a regular car.Report
