Guajardo in his article also says that before 9/11 even happened the tsa was never even heard of at the time and the tsa was never even formed until 2005 then chaos started to erupt with security issues. The author John Carter of the article (outsmarting terror. Airport/ airplane security article media group,) 2004 06 (2012) says that not only are terrorists getting smarter at what they do they are finding ways to get past all types of security measures which goes to prove that while the united states may be trying to make the latest and greatest airport security technology, terrorist are also innovating themselves trying to find new ways to get past that type of security. Carter goes on to say that our body scanners and x-ray scanners are not even tested before they are even shipped out to airports nationwide and that is a primary factor as to why terrorists know so many different ways to get around our security. Carter even mentions that the effectiveness of these machines also depends on the personnel that are using them. The author Rodney Wallis of his article how safe are our skies? 2012 (assessing the Airlines responses to terrorism.), retrieved from. PG (56) 2005) in further research goes on to say that not only are pilots becoming concerned about the effectiveness of people boarding their planes but they are also concerned about the procedure of how pilots are screened before they even get to the gate. Wallis goes on to say that there has been research done with a look at the history of hijackings and have concluded that since 9/11 pilot's terrorists have been able to make fake ids allowing them to disguise themselves as fake pilots to get on board to aircraft. Wallis in his article goes on to say that terrorists know what to look for when they are hijacking the aircraft for example they know where the black box is which is the device that has a recording of all of the events that took place on the aircraft.
