A Gallup poll given just after the 2009 Christmas Day bombing attempt suggested that 78 % of American airline travelers approved of body scanners while 20 % disapproved . 51 % indicated that they would have some level of discomfort with full-body scans , while 48 % said they would not be uncomfortable with the idea . The poll was given in the context of the 2009 Christmas Day bombing attempt , and some opponents of full body scanners say that the explosives used in that bombing attempt would not have been detected by full-body scanners
