What Level Of Skill Was Required To Fly A Plane Into The Pentagon ?

a reply to: JMack674

An interesting theory about this plane is that it's possible it was meant to his Building 7 in New York

If so why was United 93 on course South East toward Wash DC ?

Why did hijackers dial up VOR navigation beacon at Reagan National (which is 1 mile from Pentagon) if heading to New
York ?

Mental gymnastics or not, that is patently absurd. Happened 3 times, in one day - 2 of said buildings were SPECIFICALLY DEISIGNED with the possibility in mind of a collision from an airliner. In fact it was designed to withstand multiple impacts from a 767 (larger than a 747) as a safety redundancy. The architect himself said so. The idea the top portion of the building can warp and crush and obliterate into dust the rest of it underneath is also fantasy.

WTC were not designed to resist collision from aircraft - engineers did calculations to see if building would topple
if struck by airliner

Determined it would take 17 million foot pounds of lateral force to topple building - airline crash would generate
force of 13 million foot pounds

ergo build would not collapse which is what happened

Now the NEW WTC 1 (Freedom Tower) and WTC 7 are designed with aircraft crash in mind

The stairway and elevator shafts are lined with 2 1/2 feet high street concrete

The Freedom Tower has no windows on first 10 story (100 feet) to resist truck bombs and vehicle impacts

So much so is sometimes called world's tallest bunker......

Do you want to keep going with fire codes, building codes, and the methods used to fight fires were not directly changed because of 9/11?

Do you want to take your hurt credibility and disappear, or do you want to keep making false arguments in long erroneous rants?

By the why, individuals have pointed out in ATS threads the WTC was built not to modern standards. They may have been departures from modern standards. I know the WTC towers were designed before a major change to building codes. Studies have shown the WTC steel had deficient fire insulation.

Building Safety Codes Changed as a Result of 9/11

HAVE WE LEARNED THE EVACUATION LESSONS? A COMMENTARY
10/01/2002

www.fireengineering.com... evacuation-lessons-a-commentary.html

Despite its long history as a fire safety measure in buildings, evacuation did not become a prominent topic of discussion until the September 11, 2001, attacks on the World Trade Center (WTC). Even with the events of September 11, widespread calls for reconsidering evacuation procedures for large high-rise buildings came mainly from advocacy groups such as the Skyscraper Safety Campaign (SSC) (www.skyscrapersafety.org).

9/11: A SPECIAL 10TH ANNIVERSARY REPORT

Following the terrorist attacks of September 11, NFPA launched a widespread effort to strengthen codes and standards for first responder safety, the built environment, emergency preparedness, and more. Ten years later, those efforts continue ­— and they’re making America safer.

Sorry, the reason the government reports are a joke is the concerted effort to cover the incompetence.

And individuals have made the case in 9/11 threads the NIST reports may be protecting that the WTC towers were not built to code.

The towers lacked a concrete core that have help prevent the total collapse of other high rise buildings. Example Madrid Windsor.

Madrid Windsor Tower
www.911myths.com...

Dr. Pal Chana of the British Cement Association demonstrated the relative likelihood of floor collapse in a steel versus concrete framed building, using the vivid example of the Madrid Windsor Tower fire which raged over 26 hours on 14-15 February 2005. This former landmark office block of 30 storeys featured a concrete core throughout, but with concrete columns up to the 21st floor and steel columns between the 22nd and 30th floors. Remarkably, despite the intensity and duration of the fire, the concrete floors and columns remained intact however, the steel supported floors above the 21st floor collapsed, leaving the concrete core in-situ and exposed.

WTC had only 3 stairways - 2 of them, the outer A & C stairs were only 44 inches wide, just enough for 2 people
to pass by, inner most B stair was 56 inches wide

The stairway size was set in 1918 ! This was at time when few buildings more than 10 story

Same with TITANIC, which following Board of Trade regulations had 20 lifeboats, actually 4 more than required

The regulations laid down at time when ships less than 10,000 tones, TITANIC 4 times that size.

Government regulations often lag behind advances in building construction - often can be exploited by developers
who claims are in compliance with the law
