In the 'Mail' today by the transport editor is a harmless article about the proposal for sky marshals; that is until the fellow returns from lunch to finish it off.
Tony Blairs official spokesman said "These people will be specially trained. This is not taking a bobby off the beat and putting them on the airplane".
Like on El Al flights, marshals may use panic buttons in their seats to warn the flight deck of any trouble. If the pilot receives a warning signal they would roll and dive the aircraft to overbalance anyone standing. Oxygen masks would drop simultaneously to the sky marshals seat only, giving them an edge over a hijacker.
Presumably after rolling and diving the 'pilot' would then 'pull through' to assist in the 'overbalance' of anyone standing.
As a pilot of average ability, I think the only thing I would do after 'rolling and diving' would be to 'follow through'
