Another OSHA warning of why not to get into a machine: a guy in Indianapolis got inside a disabled plastic pelletizer machine to see what was the problem. The machine turned on with him in it. http://www.foxnews.com/us/2016/11/12/worker-crushed-to-death-by-recycling-plants-machine.html

I mean i shouldn't be surprised given how lax safety is on everything the chinese do but how the gently caress do you get this far in a space program without developing the concept of the range safety officer

The fuels used in commercial launches in the US are pretty safe to be around after they've all combusted. It's the military rockets that use the nasty fuels, mainly because you can't spend an extra hour doing propellant loading on an ICBM after war is declared. Of course, the materials used to build the rocket itself can have their own issues...

this is kind of common in hilly areas, maybe a bit less extreme than that. in my childhood neighborhood one of our neighbors had a driveway that steep. the night before snow was scheduled he'd go out and spray down his driveway with a garden hose, then in the morning he'd call in to work and say he couldn't get out of his driveway because it was iced over. this excuse works pretty well in the south because it only snows like maybe once a year. then all the neighborhood kids would go sliding down the ice. he was a cool dude

Nah, modern ICBMs use solid propellants, which are pretty safe. They stopped using the hypergolic ones cause they eroded the tanks when stored for too long. I still find it pretty funny that the Space Shuttle had no launch escape system. Spend billions of dollars on your next-gen manned space vehicle, but make it so the crew is guaranteed to die if the bomb they are riding on happens to blow up.

If they just added some parachutes to the top of the crew cabin then that would have been enough of a launch escape system. For some reason they built the crew cabin robust enough to survive the Challenger explosion, but forgot to add parachutes so it didn't crash into the ocean at 200 mph.

Basically the space shuttle crew was trapped on board no matter what happened from the moment the SRBs ignited until the SRBs separated. This roughly 2 minute time period is also when one of the shuttles exploded. Welp. E: also the only "abort" plan available while the SRBs were burning was for the Range Safety Officer to detonate the vehicle. Or hope the problem didn't do so until SRB sep and they could try a RTLS... and no one is quite sure if the shuttle would have actually survived the stresses of the RTLS pitch-around maneuver, which involved turning around to fly backwards with the external tank still attached at hypersonic speeds. The space shuttle was not designed with crew safety in mind. FuturePastNow fucked around with this message at 07:39 on Nov 13, 2016 |

Jerry Cotton posted:That's why they're always* stored outside. Funnily enough that can be risky too - a place in Essex went up a few years ago and they believe the fire was started because the bottom of the stack started to compost after a very wet (and quiet) winter and then dried out - dry compost is a known spontaneous combustion risk.

Isn't the shuttle moving at a fast but still manageable speed when the SRBs are attached? Because B-58 Hustler pods!

Sure, everyone on the flight deck up top are okay in their hustler pods, but those scrubs below are riding that train all the way to the end of the line.

They had one of those Double-Helix waterslides in Florida, and it was the worst. I didn't see a single person ride it more than once. It's so violent, you get slammed into the walls the whole way down. And about halfway down you can't breathe because the water is just everywhere.

The best waterslides are loving verts that kids like me were too pussy to do. They should all other individual person slides with vertical slides, just 60 vertical slides and a couple lazy rivers. No goddamn lines.

As much as I love him, I don't think he was really qualified for the job: "In October 1994, Bruce Campbell, a safety specialist with Astrotech Space Operation..." Also regarding the bridge, I think I figured out a relatively cheap solution that wouldn't involve replacing the sewer or raising the tracks: just install a ramp and have trucks go really fast through there: Before:  After:  The ramp could even be raised hydraulically to let normal traffic through. Too bad Sketchup doesn't do animation.

Unless you can unbuckle your seat while strapped in laying on your back, open the hatch, run to the zip line escape baskets, wave goodbye to the poor bastard that remains on the tower when he presses the release button faster than a rocket loving explodes, I just don't see the point?

There were quite a few possible problems (cabin fire, fuel leak) where you'd have 20-30 seconds to react and would want to use them to get as far away as possible. Obviously the launch tower would have been retracted by the time it came to actually light the fire, so the system wouldn't have been any use then.

When qkkl said "launch escape system" he meant the solid rockets that were/are attached to Mercury/Apollo/Soyuz/etc that are powerful enough to pull the capsule to safety if the rocket explodes. Yes, the shuttle had escape mechanisms that would have been useful in some limited circumstances, but if the multiple tons of explosives you were strapped to decided they didn't want to sit around quietly anymore you were hosed. That's not the case for (almost) any other manned spacecraft ever.

Is the LES a manually triggered system or automatic like a car airbag? I can't imagine human reaction time to be fast enough to outpace an explosion.
