As a precaution for their personal security, private citizens hijack a US airplane

flying out of a Canadian airport; what would be the reactions throughout the United States to media reporting of such an event? Note: the media doesn't always report the complete and correct story right away. Consider Jessica Lynch (see Reference #1 below).

Example scenario:
Four young men have had military training together and remain friends. One was born in the People's Republic of (... Most Favored Trading and Best at Using Tanks to Clear Bicycles To Enforce The PRC Outdoor Fire Code, Anti-Crowd Code, Anti-Public Assembly Code, and Anti-Free Speech Code ...) China.

Another was born in Syria, famous for being the birthplace of Maher Arar, a man who, had Saddam Hussein never lived, would hold the record for best concealer of weapons of mass destruction by a man born in the Middle East. (See Reference #2 below). The two others are Canadians of European descent (like George W. Bush and Jeffrey Dahmer), but all four became Canadians at young ages.

Now, what legal contract are Canadians who do not happen to have dual Canadian-USA citizenship irrevocably legally committed to when they pay to fly on an airplane?

What if the airplane is not scheduled to land in America, but there are mechanical difficulties or weather conditions that influence the pilot to announce that there will be an unscheduled stop-over on American soil?

The four young men, who might be traveling for business reasons or social reasons, decide that it's not a good policy to wait until after one of them has been tortured. If the airplane lands on US soil, then they might have no options.

They hijack the plane, announcing very clearly that nobody will be hurt. Then what? Will the Canadian government authorize American jets to enter Canadian airspace to "accompany" the airplane to a landing location? Will it be a location on Canadian soil or a location on American soil?

Actually, I am hoping that someone can provide those who view this thread (and that includes me) with a good reference for facts about that story, about the reporting of that story, and about the residual impressions on various segments of the general public.
