If you were a military man planning the WTC destruction for 9/11, and you wanted to conceal the obvious (see Randi about illusions), how would your plan look when you were finished? The entire WTC is your playground, and one of your prerequisites is BIG SHOW. You know, shock and awe.
Now, a production this big would require backup plans in case of certain failures. Most military planners will attest to that.
After you place yourself in that mindset...what was plan A, plan B, plan C?
To catch criminals, you must think like one.
I agree with much of that. I saw the WTC Tower collapses on TV in Wales - they showed the plane collision and the collapse in sequence - it was ages before I realised the ~1 hour delay.
My first (civilian) thoughts were horror and "Oh you evil bastards"
(Actually my first thoughts were "Is this some special effects in a movie?" ...but pass on that)
Then my civilian brain gave way to my military one and I revised to "Oh you brilliantly clever devious and evil bastards - well done" (Remember - Military Brain admiring the professional job.)
At that stage thinking it was "Crash immediatly followed by collapse" I saw it simply as "hit some distance from top - top bit falls and crushes the rest."
Lots of people on both sides of the argument are still locked into that view of events. Suits the truthers because it requires massive energy which they can claim isn't there. Then the "no demolition" debunkers - even some of the best - still make the same error. Lucky for them there really was energy to spare so thew get the answer they want but their logic is wrong.
Later I had to work through the real scenario and only two years back felt challenged to work out how it actually happened. An aquaintance is a "committed to any conspiracy" type. UFO's and Vapour Trails under the NWO are his thing with 9/11 a lesser interest. So I tackled the technical question of demolition or not. I then got involved in an on line forum and decided to deal only with technical. Simple really - explosives (or incendiaries) neither know nor care who put them in place or pushed the button. The technical evidence stands apart from the conspiracy and social domain stuff.
So it was 5-6 years after 9/11 before I worked out how it happend and became familiar with most of the funny ideas.
Now back to your "put yourself in the mind of the other side".
True. Around the Kuwait Ware (Gulf War 1) I was responsible for emergency management for a large water authority (Sydney, NSW, Aust) and worked through all the scenarios for terrorist retaliation against Aust as allies with US, UK et al in Gulf 1.
Best approach going - put yourself in their mindset.
Also worked with Aussie army on how to demolish water supplies but drifting too far OT. So I agree - think like they do.
It would be easy to bring down WTC Towers provided no interuption and no need to conceal activities. But covertly achieving it as a top down collapse which looked like Aircraft caused it is a far more difficult trick. Even now with benefit of hindsight.
