And finally, something I have neglected to address until now is that your number of satellites is wrong. Starlink is planning to launch almost 12,000 satellites, more than double your claim of 5,000. In addition to that, the system is expandable, meaning if 12,000 isn’t enough, they can launch more to meet demand.

If all you have is that I misread one stat and that somehow that means you’re right, then you are definitely arguing in bad faith and aren’t truly interested in an honest discussion. If you are truly trying to have an honest discussion, then please prove all my other points wrong with hard facts, data, and solid logic. I’ll wait.

Also commenting for Medscape Medical News, Gianluca Esposito, PhD, assistant professor, Nanyang Technological University, Singapore, and associate professor, University of Trento, Italy, agreed that although the findings were very interesting, "both studies are still very preliminary, as it is not clear how and why the treatments are really working."

Throughout the history of air travel, advances in safety have usually come as the result of disasters. The impact of the crashes of the last decade is still reverberating—in new regulations and in innovations that promise to help future investigators. But any emerging technologies, whether they be data streaming, cockpit video, or deployable recorders, will likely supplement traditional flight recorders, not replace them. At least for the foreseeable future, the time-tested black box is here to stay.

So if companies like AT&T and Dish are actually trying to adapt to reality, why are they seeing such major departures? Many of these users were on unrealistically cheap discounted promotions intended to drive adoption that ended. And some users were frustrated by the a price hike by AT&T in the wake of its latest megamerger with Time Warner. New streaming companies are also actually good at customer service, something the cable and broadband industry hasn’t been able to get a handle on for the better part of a generation.

Traditional 10 Mbps Ethernet also uses coaxial cable, just like cable TV (actually the cable has slightly different specifications). A coax cable consists of an inner wire wrapped within an insulator which is in turn surrounded by an outer conductor. So the inner wire is protected against electromagnetic interference from the outside, and the outer conductor is grounded so it’s not susceptible to interference, either. This makes it possible to use the same TV channels for cable that are also used for broadcast over the air (within reason, because, in practice, the shielding isn’t perfect).

The limited bandwidth is to be mitigated by having several thousand satellites up in the sky, all operating in a mesh network so that you don’t overwhelm any one single satellite.

McComb says the NTSB receives on average 550 to 600 devices a year, and that number includes data and cockpit recorders as well as GPS units, iPhones, and tablets—reflecting the growing popularity of aviation apps, such as ForeFlight Mobile and Garmin Pilot, which have digital logbooks and provide tools for flight planning and navigation. The prevalence of private pilots recording their own flights has provided investigators new tools in deciphering the causes of general aviation crashes, but also new challenges. The agency has devoted an entire room to extracting data from these devices, which, unlike black boxes, are not designed to survive accidents. Recorder specialists must rely on all sorts of high-tech tools—high-powered microscopes, X-ray machines, and the like—to survey and repair tiny damaged memory chips. “All this,” says McComb surveying the space, “never even existed 10 years ago.”

Let’s look at three categories of usability and density improvements that enable headend transformations without service interruptions:
