Cutaway artwork of the Douglas D-558-I Skystreak, a transonic research plane designed and built in the mid 1940’s for the US Navy. Like the contemporary Bell X-1 rocket plane, it had straight wings; but unlike the X-1, it had a turbojet engine and could take off under its own power. It could only get supersonic in a dive. Douglas followed the D-558-I with the D-558-II Skyrocket, a very different and much more advanced aircraft that could fly much faster.

The full-rez scan of this cutaway has been made available to all $4 and up APR Patreons and Monthly Historical Document Program subscribers. It has been uploaded to the 2020-03 APR Extras folder on Dropbox for Patreons and subscribers. If interested in this piece or if you are interested in helping to fund the preservation of this sort of thing, please consider becoming a patron, either through the APR Patreon or the Monthly Historical Document Program.

People are freaking the hell out. Not surprising given the reporting in the media… a combination of actual bad/scary news, and overblown hysterics. I am, perhaps oddly, fairly calm about things even though I know that if *I* catch the Wu Flu chances are pretty good it’ll kill me. Anyone been on this blog long enough may remember a number of bronchitis episodes some years ago that almost did me in then… something like the corona virus seems like it would ride the coattails of that issue to piledrive me straight into my grave. Yay. But a whole lot of people are losing their damned minds to panic. It is thus incumbent upon the media and the political leadership to try to put forward a calming influence.

And then THIS article comes out:

Asteroid Could Cause Atmospheric Explosion If It Gets Too Close

But the article *ends* with:

CNEOS said the asteroid is expected to approach Earth on March 18 at 11:15 p.m. EDT. During this time, the asteroid will fly past Earth from a distance of 0.04241 astronomical units or roughly 3.9 million miles from the planet’s center.

For frak’s sake. That’s not even close from an astronomical standpoint. There’s no valid math that would put that asteroid on anything like an impact trajectory, and thus “could” is in my opinion inaccurate to the point of dishonesty.

There are few enough stories of new government initiatives actually succeeding in doign anythign useful. Look at the SLS, for instance,  But here, at last, is a project that has not only succeeded, it should be emulated:

Most Interior Employees Reject Mandatory Reassignments, Secretary Says

The Bureau of Land Management, which deals almost exclusively with land issues in western states, wisely is moving form Washington D.C. to Grand Junction, Colorado. Given that the only reason to be in D.C. is to be near other government agencies, and nobody *needs* to be near other government agencies to do their jobs (since we have these things called telephones, fax machines, email video conferencing, etc.), moving to where the job is actually relevant makes all kinds of sense. And so in November 2019 173 employees were told that their jobs were moving and to reply by December if they were moving with them. As of December, about 80 had replied in the affirmative. With luck, the other 93 or so have been given the opportunity to explore new career opportunities.

And here’s the best bit:

(Interior Secretary David ) Bernhardt told lawmakers he has no concerns about unfilled positions, saying BLM is hiring at the local level to backfill any vacancies.

Good. Who would be best to understand the nature of BLM issues than someone from western states?

With the Wuhan Flu force-demonstrating the utility of telecommunications and also the need for decentralizing and de-densifying governmental systems, the BLM bailing from D.C. should be only the first in the scattering of the Fed Guv. NASA headquarters? Why not Montana? Social Security headquarters? Try Nashville. Or maybe Sioux City. Leave D.C. for just four things:

1: White House

2: Congress

3: Supreme Court

4: Museums

Spread the actual governmental apparatus around the whole country. This would play merry hell with lobbying… which would be a *good* thing.

A 100-watt lightbulb is no big deal, and quite often very insufficient to provide adequate lighting. But of you can make all one hundred of those watts into a single color, collimated into a series of parallel beams with a total cross sectional area of much less than one square inch, there is really only one rational category of response:
