OK, I know it doesn’t scan, but the punchline is that he couldn’t.

Sit up, that is.

He was glued to the seat.

I hate when that happens (though I think that I would have noticed something amiss long before I got stuck, but perhaps his derri

They Have One Big Problem

These morons, that is.

As a result of their failed ideology, we have the guns. If I believed in God, I’d thank him for the Second Amendment. I’ll thank the Founders instead. Let’s just hope that the Supreme Court doesn’t completely eviscerate it, as they have much of the rest of the Constitution. Certainly Republicans haven’t helped much, so far.

Yes, I know this is a weird post to be the first one in a couple days. What can I say? I’m busy, and, to quote Jayne in Serenity (a movie that I just saw a couple nights ago for the first time), the site damaged my calm.

The Hybrid Myth Continues

Michael Belfiore updates his previous post, to indicate that Rocketplane (as I was quite confident was the case) has in fact been in discussions with the FAA. But he persists in his misguided (in my opinion) fear of liquid propulsion:

I say a good healthy dose of skepticism never hurt anyone about to climb into a commercial spaceship fueled with explosive liquids.

While not denying that skepticism is always appropriate to some degree, he still seems to think that hybrids cannot explode. That would come as a shock to many (including me) who watched an Amroc 250,000-lb-thrust motor launch itself down the mountain up at the rocket lab in the early 90s, as a chunk of rubber got caught in the throat, blocking the flow and causing the internal pressure to build up to the point that it blew the bolts on the aft bulkhead, with spectacular results. Hell, even steam boilers can explode (this killed many people in the early days of river transportation).

It’s true that a hybrid can’t achieve total combustion in the same way that mixing liquids can, but it’s a big mistake to think of them as intrinsically “safe” (a term that is always relative, and never absolute). I would personally feel just as comfortable on a vehicle powered by one of (for example) XCOR’s rocket engines as by any hybrid, because I’d be confident that they would build adequate margins and safeguards into it to make it as safe as reasonably possible.
