Future's End
Both Voyager and a 29th century Federation Timeship, the Aeon, are pulled back in time to Earth in the late 20th century. The Timeship Aeon crashes in Arizona during the 1960's, while Voyager appears in orbit around Earth during 1996.

Voyager must find a way to stop Starling, before his attempted use of the timeship destroys Earth's Solar System. Meanwhile, while trying to rescue Paris and Tuvok, Torres and Chakotay are captured by a militia cell who believe that they are from the government.

He can travel all over,the same as any other crew member.

"I offer you a Vulcan prayer, Mr Suder. May your

death bring you the peace you never found in

life." - Tuvok.
