In terms of that collaboration, on the ground when I'm able to visit a ship, a potential aircraft, and so on, they talk about that ability in a more research or surveillance intelligence type of way. I was on HMCS Halifax and then on a Boeing plane that's being used for that surveillance, potentially. It certainly is in the States.
They drop mechanisms, ultimately, to detect those submarines. One of the big questions I had is, how do you recover a lot of what's being dropped, as it falls to the sea floor? Can you talk about that kind of waste, the environmental impact and how we're making changes in that technology?
