The full-body scanner, do you mean?
Yes, it's generally a more reliable machine. But as with any kind of technology, you're going to have the bleeding edge of technology at which new developments are going to have their problems, and we need to work through them.
I would point out only that the type of machine that was given trials in Kelowna is indicative of where we're probably going to head in the future. It essentially combines three systems to screen passengers. The big letdown there is throughput. You'd have to buy a lot more machines and open up more lines.
