Seems a bit silly to be leaving this up to chance

An update:

The Pentagon is tracking an out of control Chinese rocket expected to crash into Earth

The Chinese Long March 5B rocket is expected to reenter Earth's atmosphere around May 8. No one knows where. But don't panic!

I guess they were modern times back then, too... Future generations will be making the same observation... Interesting how someone arbitrarily set the limit at 10 (tonnes?)tons, as opposed to 20 tons ... I would have thought that the rules would preclude anything 'dangerous'(not totally controllable) from coming down.

The space shuttle Columbia was 80 tons.

It’s not a good precedent to set to do it on purpose. But as worry goes, there’s hundreds of tons of stuff flying over me on any given day of the week that could come down unexpectedly.

I was aware of the bunch of space junk... just don't give it much thought.

Looking at the tracking data, it's maximum latitude is around 43 degrees...I'm up here around 47, so no worries for me. Sucks to be the rest of you guys nearer the equator, though. Maybe the Chinese space agency should yell "fore" before each launch?

 

[RedSnake]

"fore"

Yes, we're closer to 34˚ N latitude

You can move... summers are generally pretty good in Canada. We're north of the 49th...

looks like its going to be 8th or 9th of May.

Booked.

CNN said it cound leave a 100km long debris field.

Does China have insurance for that kind of thing?

...as worry goes, there’s hundreds of tons of stuff flying over me on any given day of the week that could come down unexpectedly.

I often gave tours of a former employer's large engine plant where one line ended with ~10 ton engines hanging ~20' up from a rail traveling across a main aisle. It was a busy plant so folks rarely noticed the engines going overhead in that area, allowing for one of my favorite jokes - pointing up and reminding folks of their weight just as we walked underneath. Some of the facial expressions and walking routes were priceless (but never concerning) but I suspect there was complaint bc the aisle was eventually rerouted for no perceivable reason.

 

[phamENG]

the aisle was eventually rerouted for no perceivable reason.

just as we walked underneath.

I think that was the reason. My experience in industrial environs - steel mills and ship yards - you don't walk under suspended loads, period. It could be an empty BTH device, you walked around. And when nothing was on the hook, it was parked such that a sudden failure of the cables wouldn't drop the hook onto a walkway.

 

[cranky108]

We suspend energized power lines over roads and walkways all the time.

Is it just a matter of perception, or the risk involved?

 

[phamENG]

Good point, cranky. Probably a bit of both. Qualitatively speaking, we started stringing up power lines over our heads even before we were free climbing the Empire State Building's frame and riding the hook on the cranes, and I'm guessing the track record for performance of that cabling is much better than for rigged loads.

There's also a risk/reward aspect: in a factory, a worker loses 45 seconds every hour because they have to go around column A to the left instead of the to the right. That math works out for me if there's a risk of being crushed by something because somebody was a little too tired that morning and didn't thoroughly complete their pre-shift rigging inspection. But if you have a cable that doesn't move (except for wind, birds landing on it, etc.) that's fixed in place using methods proven to work over a century of experience with a vanishingly small failure rate, I'll walk under the power line if the alternative is to cut off power to a million people just so I can walk my dog.

With that said, there is a push where I am to move electrical infrastructure underground. Granted, this is more for reliability in a hurricane prone environment than everyday safety, but the latter is a positive if unintended consequence.

In Alistair's link it disappears here the 14 of may not sure how accurate it is.

Thats just a cut off point, no point crunching the numbers after that it will be down days before that.

That is just a cut off point ??? meaning..
