Ted Stevens, who was voted out of the Senate in 2008, has gone down in a plane crash in the Alaskan wilderness. Reports are that he has died, but it doesn't appear 100% confirmed yet. (EDIT: It is now.)
Stevens, now becomes the second Alaskan member of Congress- out of 11 all-time- to die in a plane crash in the Alaskan wilderness. Nick Begich did so in 1972; his body was never found.
From this, we can of course only conclude that if you are from Alaska and you get elected to Congress, invest in a dogsled.
