Unless you're flying on a plane with 14 Syrian musicians who are constantly running to the bathroom and passing things around to each other and winking and nodding and reading the Koran. In that case, just shut up and sit down because we can't do anything about it until the bomb actually goes off. Then we will have proof that a crime has been committed and THEN we can arrest them...
The other thing that should have happened, is that the pilot should have landed the plane at his first opportunity.
