I agree that hardly anything was learned and applied in light of the collapses from a building safety standpoint. The government efforts to forensically determine the collapse mechanisms were highly politicized, secretive, and not published in peer reviewed journals. You would think that the failure of 3 steel framed massive buildings in one day would spurn a revolution in building design, but it seems like the collapses are being treated as totally and utterly anomalous.

Agreed to all.

Lol. Yes Bobo i think the costs would be relatively low especially if you value one life at 2-3 million dollars or however high a life in the western world is now valued. Cuepee if I'm ever looking for a tag team partner at the wsop I would ask you first.

You're actually providing good points. I think you might do this to find a solution. Buildings should be safe, period imo. And it wouldn't cost too much. Think about how much they invest in such building in NY or how much they make. Then I think invest 0.01 of that in a escape tunnel/chute. I actually don't know how much it would cost buy j think it has to be there. How much did an office place, flat or one floor cost in the word trade center? 20 million? 250? 850M? I think for the cost of one floor they could arrange an outside or inside emergency escape option.

Sorry buddy my rope is only made for one so it won't end well for you if you try to climb on.

LOL , cliffhanger...

Holy **** man, have you seriously not given up on this yet??

You're talking about evacuating thousands of people via a drop of, in some cases, over half a kilometre. Half a ****ing kilometre. How you think that's going to be managed by going out through windows and down a rope or slide is beyond me. How you can think about this for more than a couple of minutes and not abandon it as completely unworkable, is perplexing. The logistics, the huge risk of people dying while engaged in an outside escape attempt, and then the increase in suicides or even accidents or suicide attempts with opening windows are all issues you continue to ignore or hand wave away.

You talk about the cost and what we value a life at. The loss of almost 3,000 people was tragic, but what you ignore is what the actual risk is here. There are thousands of skyscrapers around the world, with millions of people occupying them, every moment of every day. They have inside emergency escape options already, built to withstand most emergencies, but not planes being flown into buildings. So the question is, over the 100+ years of skyscrapers' existence, how many planes have been flown into buildings? Does it make sense to spend millions of dollars in every skyscraper on dubious slide schemes in case a plane will be flown into it?

Talking about inside options makes a lot more sense. And of course, people are:

But let the outside stuff go, dude. There's a reason that outside escape options aren't used beyond a certain height, and it's not because they don't care or want to spend the money - it's because it just isn't feasible.

And as much as I like having fun with the idea of it Bobo is correct.

Almost certainly you would have far more people die trying to take matters in to their own hands to save themselves and utilizing these extreme escape measures just as help arrived from the Rescuers that would have actually saved them.

Even for me, with my experience in Rock Climbing and repelling. Is the best decision to try and repel all the way down the WTC which would take hours, only to then find out after they landed a helicopters on the roof and were evacuating people that way? And because it takes me so long to repel the tower collapses and I die when a roof exit would have saved me?

No, the fact is that in these extreme events, if you manage to survive, having most people not try to take their own safety into their own hands via extreme measures will almost certainly result in a better outcome.

I however am still going to try my extreme escape, despite the knowing that. Somehow I would be more content knowing I was about to die fighting for my life than just sitting waiting and have death claim me while i felt helpless.

I want the opportunity to escape the Elevator and climb out and try to escape the rising flood waters rather then hoping someone pops the doors open and saves me. I would attempt to repel down rather then letting the fire just climb up and get me.

I usually avoid doing this, unless I see the same mistake repeated over several posts; I hope others would do the same for me if needed.

Rappel, rappelling.

Something I'd like to try one day. But maybe not from a skyscraper, at least not the first time.

fairly technical endeavor that requires several hours of training and practice. And then there is the cost of the harness, which must be fit to the person wearing it, the hardware such as carabiner(s), figure eight or equivalent, the rope is over a dollar per foot.

Throw in some fire and everything changes. If I spent a lot of time in a tall building and was really worried about it, I would probably go with an espape parachute which has it's own risks, limitations and costs.

Carp Die

LOL.

I can only speak for myself and say I like the correction as it does not show up as a spelling error and thus I would not change writing it that way.

Check it out. This guy is 58 years old and called the Spider-Man. He climbed 150 something skyscrapers and holds all the records (towers) yes and Bobo scratch the outside options, inside tunnels are fine too



Cuepee, the guy I was talking about who climbs towers.

Or actually let's look at outside options real quick:

I'm thinking something like this, Like a robot or something you know? Must be technically possible to have something like this with all the batteries and AI options. I'm thinking like a mars rover that can bring down people safe. Applicable to any building. Has just to be carried to the site. Like this only bigger:



Or I've been doing some thinking, I think they haven't thought of this. It only needs to be invented. An extension to a helicopter. It must have something like a long pole attacked to the heli. The problem was the copters couldn't reach the people, right? So why ffs not invent something like this, they already did invent an extenision, why not for people? Someone has to come up with something, that's all!

Check it out! Only the pic here so u know what I mean:



Instead of the blades something else that's all it needs. A rescue box! Weightwise and techincally no problem. Chinook helicopters can easily carry 10 people imo. So instead of a 50m extension you would need a 200m extenision that's all damn it!

The evolution of towers is great!





But not of the rescue options! Watch more sci-fi movies and become creative, engineers!

Here are some cool systems for repelling inside, they are called personal lifts I think:







for bigger buildings you only need a longer pole. Attach a box instead of blades for treecutting.

You might find this video interesting. Also any 9/11 truther, they explain the construction errors and what was learned from it and applied to newer buildings. Interestingly, there were plane collisions in the past and they anticipated that, they had to at that height of the tower. But not at full speed, not at 400 miles and not from a 737. The tower was made to withstand a plane crash at ~140 miles and from a slightly smaller plane.

The 2 only stairs were too close together so the plane could damage both at the same time. Now they try to put as much space as possible between. They also added or try to add a 3rd stairway in newer buildings. So I take it back a bit. Acc to this video a few things were learned. What they also learned is that concrete is a much better shielding, not iron, from impact and heat. Also not to use this contruction ever again. It was a innovative construction they used, and they will not use it again anywhere I think.

You and Deuces should share each others contact info and work together and come up with a detailed plan on this topic. That way you can then present one coherent thesis instead of constantly spamming threads with your stream of consciousness topic of the moment YouTube videos that nobody else will click.

All the best.

washoe I enjoy the 'fun' theorizing about way out tech solutions but you need to indicate you are joking, understand these proposals you make are a practical impossibility but you are just having fun with it.

I want you to think about how many tall condo's and Office towers there are and the impracticality (not just cost) you are suggesting for a problem that really does not exist outside a few outlier examples.

And science is working on the ultimate fix for this so you can take solace in that. One day we may have Star Trek like Transporters and in any incident like that we will all just be transported to safety.

So stay calm and be patient, a solution is on the way.

I assume you are joking when suggesting he may be joking. I am not joking.

Also, a lot of transporter malfunctions happened on that fictional TV show, so why would anyone want to use that technology!

You want my recommendations for more robust building construction in light of 9/11? I'll give them to you now - change nothing.

Actually, I want you and the YouTube addict to work together to form a kind of think tank to discuss this important issue. At that time the two of you together can outline your thoughts as a super team, and I will place the appropriate amount of concern about them at that time, which I promise will be at least double to triple the amount I care about your recommendations right now.

All the best.
