I believe that all these technical issues, although perhaps more extensive than NASA has as yet acknowledged, are all solvable,

I believe that's just because they have not yet found the issue or issues that move them. That doesn't mean they won't find it though.

Such issues are precise technical details.

We have an extensive system of highways, ports, locks and dams, and airports.

I don't think the Arbitron numbers have peaked yet.

We firmly believe the environmental issues cannot be addressed without extensive public participation, but people need to be informed before they can get involved.
