Sure. There's an element of the operations of CATSA that.... At its heart, it is a security operation that uses the best intelligence on security threats and the latest technology to protect passengers from mischief. In the personal screening and the hold-baggage screening, there's always an evolution of the technology to more sophisticated x-ray machines and remote sensing. We're working on the adoption of some newer technology that allows better remote sensing of explosives without as much intrusion as you would normally see. You know, you go through and then there's the swab of the bag. There's a way to start doing that in a more remote manner using the latest technology.
In CATSA, we're always going through, every few years, an investment in the next technology to better screen for things like explosives and weapons and better protect passengers in a manner that's less intrusive as they go through the screening points.
