Point 1: The driver must be sacked and made to pay at least the amount he received from the News of the World in payment.
Point 2: The Journalist, and his newspaper that sanctioned his actions, must be prosecuted.
Point 3: At my company, and I guess most (all) others, a crew arriving at a cold aircraft are required to conduct and sign for a full search before boarding commences. Therefore these items would probably have been discovered before any flight.
Point 4: The only way we can achieve 100% security in aviation is to stop flying now!
