Whenever something important (or even not so important) in aerospace fails, a failure committee is put together to figure out what the hell happened. The magic phrase is “root cause…” the basic source of the problem, from which the train of failure that led to the disaster flowed. Of course, some systems are so complex or politically driven that the root cause is often in dispute. For example, the Challenger disaster: some claim that the root cause was design decisions made during the development of the RSRM’s; other claim that the root cause was the political choice of SRMs rather than a flyback liquid booster. Others point out that the root cause was managerial dumbassery… the decision to launch when it was too cold.

More recently, the US economy tanked. While the economy had a number of flaws, it’s generally accepted that the trigger that got the ball rolling was the collapse of the housing market. And the collpase of the housing market was driven in large part by the over-issuance of “subprime” mortgages. Basically. subprime mortgages are mortgages given to people who’s fiscal situation is so poor that they would not normally qualify for a mortgage. Subprime mortgages are mortgages that mortgages lenders pretty much seemed to assume would not get paid off. And knowing this in advance, these mortgage lenders – bankers and such – maneuvered the system so that the inevitable defaults would get dumped onto the taxpayers.

Obviously, these morgage lenders were scumbags.

Right?

Well… the question needs to be asked, why were so many subprime mortgages issued in the first place? Mortgages that are assumed in advance to probably go into default are exactly the *opposite* of what a mortgage lender would be expected to do… it’s bad business. So, why did they issue these mortgages?

Here, maybe this Los Angeles Times article from 1993 might shed some light:

Minorities’ Home Ownership Booms Under Clinton but Still Lags Whites’

Main relevant points:

1) Clinton administration enforcement of the Community Reinvestment Act which required banks to increase lending to communities that do not economically qualify for conventional mortgages

2) New efforts by Fannie Mae and Freddie Mac to buy mortgages from lenders and bundle them into securities, including incentives to the lenders

3) 42% of Fannie and Freddie portfolios were by law required to be loans for low- and moderate-income borrowers – in other words, people who could not qualify for regular mortgages.

If you mandate that banks hand out loans to people that banks *know* are bad risks, you can’t blame the banks for doing what they can to unload those loans when the chance arrives.

Near the end of the article is this creepy bit of foreshadowing:

Barry Zigas, who heads Fannie Mae’s low-income efforts, is undoubtedly correct when he argues, “There is obviously a limit beyond which [we] can’t push [the banks] to produce.” But with the housing market still sizzling, minority unemployment down and Fannie Mae enjoying record profits (over $3.4 billion last year), it doesn’t appear that the limit has been reached.

That limit got reached. And it damn near destroyed the economy.

So is the Community Reinvestment Act and related bits of FedGuv dogooderism the root cause of the economic crisis? Perhaps. Of course, the CRA did not spring out of a hole in the ground; it followed along in the train of such social engineering projects as the Great Society and the New Deal. The root cause, I would suggest, goes all the way back to the first politician who convinced government to force businesses to do unbusinesslike things “for the public good.”

On the topic of “the future as seen from Way Back When,” here is “Rendezvous in Space,” a film shown at the 1964-65 New York World’s Fair. It includes a Martin concept for an HL-10-derived lifting body spaceplane launched by a Titan IIIc to service a small space station. See HERE for another Martin HL-10 concept.

Now available: five McDonnell Aircraft Corporation diagrams of the Mercury capsule. Included are:

1) Drawing 45-00002, “Inboard Profile Model 133.” Black and white, 28,420X5380 pixels. Dated 1959. Includes a detailed interior view of the capsule along with an abort tower diagram… apparently a not-quite-final design as there are a few differences from the Mercury as it actually flew.

2) Drawing 45-32002, “Struct. Assy. – Conical Section.” Black & white, 20,664 X 5166 pixels. Dated 1959

3)-5) Drawings 45-32000, “Capsule Assembly,” drawings 1 through 3. Black & white, ~11,000X5100 pixels. Date unclear.

All drawings come full size, half size and quarter size, for easier viewing & printing, in a single 8.1 megabyte ZIP file.

Space drawing 28 can be downloaded for $5.00.

I put together a number of photos I recently took of Hill Aerospace Museums newly-restored F-104A into a free downloadable PDF booklet.

If you like this, feel free to distribute hither and yon. If you *really* like this, feel free to toss a dollar or three my way.

If there is interest, I will make more of this sort of thing… I have a vast collection of photos of aerospace and weapons systems that might be of interest.

The April 2012 issue of Popular Mechanics has an article/editorial by Glenn Harlan Reynolds that is *disturbingly* familiar. I was flipping through the issue today while waiting for the Wal-Mart pharmacy to do their thing when I came across an article illustrated as if it were a mid-1950’s sci-fi “juvenile,” and starts off with the line:

THE FUTURE ISN’T WHAT IT USED TO BE.

SCIENCE FICTION USED TO BE ABOUT BOLD ENGINEERING. SO WAS AMERICA.

Mr. Reynolds makes much the same points I’ve been trying to make, and hopefully he’s done it better. The thrust of the article is that the pace of meaningful technological progress has slowed at the same time that science fiction has become far less inspiring. Some damned good points:

“We can’t Facebook our way out of the current economic status quo”

“There was some moment in the late ’60s and ’70s when people thought we had enough tech”

we’ve lost “speed of implementation”  – “you can roll out a new social media platform or an iPhone app in a hurry, but do Twitter and Angry Birds improve lives the way rural electrification did?”

“We’ve given people new ways to communicate but nothing worth saying.”

“Facebook probably won’t save us from economic stagnation; it certainly won’t save us from an asteroid.”

“The golden age approach is just more inspiring.”

——–

It may be a chicken-and-egg thing – which came first, the end of inspiring sci-fi, or the end of inspiring reality. But the fact remains they are both currently largely absent. Go into a the kids section of a book store and *try* to find some science fiction. You’ll find instead a boatload of fantasy: wizards and vampires and werewolves and whatnot. Entertaining, no doubt, but nothing that can be achieved, nothing to strive for… and nothing to truly inspire. There are no Big Projects in aerospace these days, and little to no modern science fiction that would inspire kids. So, with nothing to inspire kids into aerospace, why would the go into aerospace? There are buckets of fortunes to be made in social media and software; almost nobody gets rich off of aerospace – and some of us get dirt poor off of aerospace. So with a culture as basically shallow as our, it is not surprising that those who might have educated themselves so that they could conquer the spacelanes now educate themselves to create the next Twitter.

Mr. Reynolds encountered a whole lot of pessimism in interviewing people – Neal Stephenson, Vernor Vinge – for his article, but maintained a level of optimism. A list of “bold and optimistic” science fiction, from Golden Age to today, is included. A few things it seems I may need to look up.

When I heard they were remaking “Dark Shadows,” I was uninterested. When I heard that Johnny Depp was playing the vampire, I was actively turned off (the whole “pretty boy vampire” thing is *way* played out).

And then I saw the trailer, and laughed my ass off.
