Okay.
So what we see is that your system actually costs less.
I'm getting back to these body scanners, because we've invested a fair bit of money in them, and I want to understand.
Mr. Salter, you said they can detect these ceramic knives. What's the threat assessment of a ceramic knife these days with the hardened cockpits? We can't weaponize a plane anymore with a knife—not like 9/11—if proper procedures are followed in the cockpit. What actually will this do? Wouldn't a sniffer system be better for detecting the real hazard, which is an explosive device?
