The first exam, Fundamentals of Engineering, covers mathematics, chemistry, physics, and engineering sciences. The second exam, Principles and Practice of Engineering, requires the applicant to solve engineering problems in his discipline plus problems in four other disciplines. The difficulty of these tests have been equated to passing ten final exams on the same day. The data covered on the tests requires the applicant to draw upon knowledge that has been accumulated over an entire college and professional career.
One of Pat's regular commenters "GuitarBill" makes the argument that AE911Truth only represents 0.23% of the the US scientific and engineering community based on a number of 600,000.
First off, he only bases this figure off the number of architects and engineers who have signed the petition, ignoring the other credentialed signatories. This figure also ignores other 9/11 truth groups with large numbers of credentialed people signed on to their ideas such as Scholars for 9/11 Truth and Justice.
Of course there is some overlap and I'm not sure how much of a difference it would make, but it would make one. Regardless, and most importantly, a failure to condemn the official story should not be viewed as an endorsement of it. One should also not assume that all individuals have been exposed to the relevant information, as the "BuildingWhat?" campaign has proved with Geraldo, this is certainly not the case. And there is no way to calculate how many have the guts to take a public stance on such a controversial matter. As AE911Truth civil engineer Jonathan Cole has stated, "there is a good reason that there is no group called 'Architects and Engineers that support the official story.'"
