Earth is doomed, who will be on the ”Lifesaver ships”?

disclaimer For now this is all conjecture on the realm of science fiction. Should a comet, meteor be destined to smack this planet, we are all toast. But look at if from the view point that there is a solution to save mankind.

Through a friend or acquaintance you discover that the government has been hiding the fact that a earth-killer comet or asteroid is headed on a collision course with the Earth. Governments around the globe are secretly building ships to ferry people off this planet with the home of making it to Mars to perhaps construct domed communities to preserve mankind. Who do you think will be on those ”Lifesaver ships”, the mega rich, government officials and their families, the average Joe? For a sense of scale let’s say the US had 350 ships in the works each holding 675 people, and 480 cargo ships with a crew of 8. Would you leak the plan or try to angle a way to get a seat on the ship or become one of the crewmen to save you? By the way, from the time you discover the information the comet/asteroid will not arrive until another 4 years and 7 months.
