Have you ever seen "I Am Legend"? If not, go ahead and watch it, because it's a good movie. To summarize, a massive pandemic wipes out most of Earth's population. In a flashback, Will Smith tries to save his family by putting them on a helicopter that is leaving Manhattan before the government blows up the Brooklyn bridge to quarantine the entire island. He watches the helicopter go up, and it seems like his family will get to safety, but a crowd of desperate civilians latches onto the landing gear, and the helicopter loses balance and goes into a tailspin.
