That's the kind of mistake I expect to see from the last few years of Russian launch SNAFU's, it's not a mistake I expect to see from ESA!
The Explosion of the Ariane 5 suggests it's exactly the kind of mistake we'd expect to see from ESA.
My suspicion is that enough people fucked up on this such that no one is really going to have to answer for any of it. The govt should not have underresourced the FAA. The FAA should not have rubber stamped a self-cert by Boeing. Boeing engineers should not have half assed the implementation of MCAS. Boeing customer service should not have neglected training on MCAS, the system deliberately designed to point the aircraft at the ground.
Paid DLC for life critical system redundancy certainly sounds criminal, but you never know.

This is understood, at least by people in this thread. That said, the ID arrangement failed to catch this particular design issue, and the FAA needs to do some PR damage control ASAP because without it this looks like a case of the fox guarding the henhouse.
AIUI, though, one of the appeals of the 737 specifically was that the pilot could in fact turn off the automation and hand fly the aircraft with no computation between the stick and the control surfaces. That makes the MAX and its partial fly-by-wire a more significant change.
Exactly. MCAS isn't autopilot; it's fly by wire. In an aircraft that to my knowledge had no fly by wire system previously.
It had saved Boeing a great deal of money and time up until planes began falling out of the sky. But basing that system on a single mechanical sensor is the single biggest fuckup out of the entire chain.

I don't know whether the commentary will be any good.

Spinlaunch appears to be an actual company that really plans to launch small rocket-assisted payloads from a centrifuge. I have many questions, like what is the side loading G rating, and what happens to the launcher after it lets go. But I thought I'd get some opinions from you guys before dismissing the idea as entirely ridiculous.
Yes, I just finished reading it a couple of months ago. RP-1 sure seemed like the "easiest" option out of all the concoctions they tried. And I assumed that progress must have been made in the decades since that book was written.
Ignition mainly. I'm a little surprised hard starts are still a thing.
I don’t see it either. A rotationally-catapulted payload would have to withstand incredible sideload forces and then the axial forces imparted by atmospheric drag and the second stage. A linearly accelerated catapulted payload would still have to withstand 1G of (downward) force plus the axial. Whereas stacked vertical launch only has to be built to endure acceleration in one direction.
And if they don't make August the launch will be further delayed because there will no longer be any open docking ports at the ISS.
That’s exactly what it sounds like. Thing is, even if they can unstick these valves, how do they know they won’t just stick again? Thirteen seems like the kind of failure rate that would require, like, different valves.
I saw Shatner on stage at Cisco Live in 2011. He was kind of overweight but not overly so, but he was already old enough that he couldn't move faster than a shuffle. Sharp as a tack mentally though, hilarious too.
Thanks for the heads up! Caught the main chute(s) deploy, heat shield jettison, and airbag inflation. A successful enough test, despite the thruster malfunctions. Hope they can sort that out.
Yeah, I just wish the actual impact wasn't lost in the heat haze.
Held a couple of times and then finally scrubbed. Not sure what the issue/s was/were.
Nice looking piece of hardware though.
It happened. I got nervous when I learned the first stage was powered by Blue Origin engines but this launch seems to have gone flawlessly up through second stage ignition. Aside from some fires on the launch pad anyway.
I'd be interested in seeing current communications between the Alaska Airlines C-suite and that of Boeing...
