Over a year after full-body scanners were scheduled to arrive as an additional security measure at the O'Hare International Airport, the area's aviation commissioner has shared that the technology is finally expected to hit within the next 6 months.

Various safety experts and politicians have expressed that the attempted attack on the Amsterdam-Detroit flight could have been prevented if such scanners had been installed before. The Chicago Department of Aviation Commissioner Rosemarie Andolino, however, has stressed that the technology at O'Hare was well in place before the incident.

As many as 150 of these full body scanner machines are all set to be distributed by the Transportation Security Administration to airports all across over the next year. But spokesman Jim Fotenos has said that which airports would get them and which would not has not been finalized yet.

As many as 19 airports across US are already using these machines, and many more are expected to now get them.

While the scanners have their set of supporters, there are other who fell that these are an invasion of privacy and should not be installed.
