So, if you read a news report saying that a recently-deceased 16-year-old girl in Britain  had suffered from racism, what image pops into your head? Was she an immigrant from Syria? Nigeria? Nicaragua? India? Pakistan? China? You know, someone you could look at and say “that person is clearly not ethnically British?”

Nope:

Ummm.

Polish girl, 16, found dead at school ‘had suffered racism’

Sure, her name might have been an unpronounceable consonant-salad (“Przybysz?”), but to my eye she doesn’t look like a different race than some form of Brit. Perhaps as an American of Euro-mutt ancestry I’m not as keenly aware of the fine gradations of ethnicity that people can kill each other over (remember Serbs and Croats whacking each other? Put ’em in the same outfits and I sure couldn’t tell them apart.

American B-52 bomber crashes in Guam

The article is pretty lean on details, but given that all seven crew managed to escape unharmed from the plane *after* it crashed (“shortly after takeoff”), and the lone photo shows the plane on fire but not scattered across the landscape, I’d guess it had some sort of engine trouble and either flopped off the end of the runway or tried to go-around but didn’t quite make it.

Whatever the cause is, I would almost certainly be unsurprised. These planes are about twice as old as the pilots who fly them. Remember the XB-70, the Mach 3 superbomber from the early 1960’s? It was intended to *replace* the B-52.

A few minutes ago – call it 20 past midnight – I was quietly reading “Abaddon’s Gate” when I heard an explosion outside. More specifically, a distant explosion. Not a single “bang,” but more of an extended “crackle.” And the direction was “up.” Took me a minute or so to get outside, but nothing further out of the ordinary. Cloudless night, so it shouldn’t have been a reflection (though the sound could have bounced off of different thermal layers, I suppose). It made me think that *maybe* I heard a small rock break up in the upper atmosphere during entry. Probably not, as that would be just too damn interesting.

Now CNN doesn;t have to cover stories about how Bernie Sanders supporters are the actual violent whackjobs that the Trump supporters were supposed to be… there’s an airliner missing! Expect wall-to-wall coverage, with hours going by with no actual new data being relayed in that time.

EgyptAir Flight 804 disappears with nearly 70 people aboard

An Airbus from Paris to Cairo has vanished like a fart in the wind over the Med, just inside Egyptian airspace. Feel free to speculate… the journalists certainly will. Was it a black hole? Aliens? Did a rift in the space-time continuum swallow the plane and send it back to pirate days or dinosaur times? Sure these are the most reasonable explanations.

CBS will air the premiere of their new Star Trek series in January 2017. The few details that have leaked out in rumor-form make it sound intriguing… it will, reportedly, be an anthology series, with each season covering an entirely different cast in a different Star Trek era. The rumor is that the first season will be set between Star Trek VI and the TNG era, on a non-Enterprise vessel, with lots of doin’s with Klingons.

Too bad you probably won’t be able to see it, because after they air the premiere, CBS will promptly *not* air any more episodes but instead stream them online behind a paywall. This right there will keep the regular viewers from tuning in, leaving it only to the actual pre-existing Star Trek fans to pony up the six bucks a month for the online access. But you know what Star Trek fans tend to be good at? Computery things. Star Trek will be pirated at a rate not seen since Game of Thrones.

I expect that I’ll watch the premiere when it airs, then pick up the “complete series DVD set” about six months later.

We’ve been hearing for some years now that the police have been unfairly targeting and killing black men. Hence the “Black Lives Matter” movement. Well, numbers, data, the facts, are the important thing in *any* discussion. Not feelings, not anecdotes, not beliefs. Not what you want to be true, but what is true. So, the Washington Post has been collecting data on police shootings and has released their 2015 findings. So, what we got?

990 people were shot dead by the police in 2015.

494 of them were white (49.9%)

258 of them were black (26%)

172 were Hispanic (17.4%)

66 were other&unknown (6.7%)

OK, so, blacks, who comprise 13% of the population, where shot dead by the police at twice the rate you’d expect based purely on population. Racism, right? Slam dunk?

But then there’s the FBI, with *their* database, “Crime in the USA, 2014.” Specifically Table 43A, Arrests by Race. Here we find that blacks make up 51.3% of those arrested for murder and non-negligent homicide; 55.9% for Robbery; 33.1% for Aggravated Assault; 30.2% for Burglary; 30.7% for Motor Vehicle Theft; 40.7% for Weapons. These all seem to be the sort of crimes that would put the criminal in the crosshairs of the cops, and properly so. This says nothing about *why* these people are committing these crimes… whether it’s due to social ills, poverty, lack of playgrounds, crappy edumacational systems, bad parenting, lead in the water, lead in the air, rap music, drug abuse, listening to the likes of Al Sharpton, or whatever, the simple fact certainly seems to be that black men seem to commit violent crimes at an elevated rate. And the interesting thing here is that they’re getting shot dead by the cops at a rate *below* what you’d expect given the crime rate.

An interesting writup on this, focusing on the category of “unarmed black men shot by cops,” is available here.

From back when General Motors was studying spacecraft, here’s an early 1960’s video showing tests of three means of surface propulsion for lunar vehicles:

The Archimedes Screw system was interesting, but it seems to me that there’s virtually no chance that it would be a good idea on the moon. The rough, razor-sharp regolith would seem likely to sandblast those shiny metal screws in little short of no time.

A 1977 Rockwell concept for how to expand the utility of the Shuttle system: move the payload from the Orbiter and put it in a shroud ahead of the External Tank. This would have allowed for much larger-diameter payloads to be carried. The ET would of course have had to go into orbit with the Orbiter itself. More info and diagrams of this are in US Launch Vehicle Projects issue 1.
