Each minimum installation would still have a footprint of many, many blocks, and a firing point (several, most likely) with a radius of 30ft or more (for safety) - they'd be very noticable. But thank you for accepting the point.
If you are referring to air superiority craft, such as fighters, I can't speak on behalf of the Air Force. I know that the limited contact we had with the AF often saw missions scrubbed or sent via surface roads, because aircraft fuel was too expensive to waste on training missions. I have no idea what they had available for actual wartime missions.
However, since the fastest attack craft would still take 10 minutes or more, after takeoff, to reach the point of contact and slow to dogfight speeds, they were also completely unprepared for aerial assault.
I was serving at Ft. Sill, OK, in the field artillery, when 9/11 happened. For many years, I took the official story quite for granted. But several months ago, I came across my first CT posts, and shortly thereafter, the Loose Change video. I was swayed, at first, by the apparently interesting arguments presented, and I spent a few days in chilly consideration of the possibility that there were truths in that video.
But then I did what I expect any rational adult would do - I started researching the material myself, as much as I was able. AND I refused to be attracted to websites of rhetoric, half-truths, ignorance, and lies. These were of no use.
I did spend hours in libraries, pouring over physics books and architectual books, anything that might help support or refute the claims of LC.
And the conclusions I came to were this: 19 Islamic terrorists managed to kidnap four passenger jumbo jets, smashing two into the WTC, causing its eventual collapse, one into the Pentagon, and one crashed into an empty field in Pennsylvania after the passengers bravely struggled against their enemies. WTC-7 collapse due to fire damage and impact damage from falling debris.
Also, that there was a possibility that bin Laden was a patsy of our own government - not that he was blamed falsely for planning these attacks, but that he might have been led into attacking us through deliberate manipulation.
There are apparently many things you have difficulty believing, which are nonetheless true.
Having lived on a ranch, I would agree with your assessment. Like a shot cow, the building suffered and 'bled' (the fires), sagged and swayed, and eventually slumped over, slightly sideways, when it could stand no more.
WTC7 dropped exactly how I would expect a building of its type to drop, after being heavily damaged by raging internal fires and after having parts of large buildings dropped on it from considerable height. It didn't fall quickly, except at the very end, but sagged and swayed as the damage increased. It didn't fall into its own footprint, unless perhaps the building's feet are considered to cross roads and meet other buildings.
Nothing about the actual events of that day are a mystery to me, any more. The events that LED to that day, however, are full of mysteries and possible conspiracies. I would have no trouble believing, for example, that the government (well, parts of it anyway) have been slowly forcing a situation by their actions in the Middle East, and deliberately NOT allowing the U.S. to prepare for it, in order to have an excuse to go to war. It's no secret that many government officials, being Christian fundamentalists of one vein or another, long for the holy war that willl crush Islam and prove the superiority of a Christian America once and for all - just as many Islamic officials long for the Jihad that will wipe the earth clean of the infidel.
But the events of 9/11? As far as I can tell, completely aboveboard.
