Near the end of the movie the police are inspecting the inside of the wrecked airplane. Two cops walk towards Johnny 27 who appeared to be dead, hanging by his arms, which were handcuffed to the ceiling.

The cops say, "Are you sure he's dead" ... "Yes he's dead". Now the cops carry his body away and we notice that his arms weren't even connected all along!

IF HE WASN'T HANGING BY HIS ARMS... HOW IS A DEAD MAN STANDING ON HIS OWN???
