I do want to get SpaceX into this as well. I'll go to Ms. Cooper first and then back to you, Mr. Goldberg.
This is probably going to be one of the more difficult questions to answer. What are the vulnerabilities you face with using satellites? What are your biggest challenges?
There is everything from international agreements to coordinating flights off the surface of the earth, and then on top of that, the rotations in space. More and more satellites are going to be up there. What happens to them for repair and a whole series of things? At any rate, can you generally outline that for people? I understand fibre optics. We can control that. That's the LAN we have and what we use.
Ms. Cooper, you go first and then Mr. Goldberg, if I have enough time.
