Valve has been very flexible with device repairs/replacements. I'd try contacting them even if the unit is out of warranty, worst they can do is say no.
Aircraft carriers don't operate alone. They have whole flotillas of support ships, few of which run on nuclear power. Not to mention all the non-nuclear-powered aircraft an aircraft carrier carries.
I've heard that courts have ruled that airports count as "the border" too. So anywhere within 100 miles of an airport. So basically anywhere in the country.
