Yes tis most sad; when I was (a lot) younger the Captain would sometimes have a minature Company model aircraft to give cockpit visitors (cunning marketing really - and yes I know its a flight deck now, but this was then).
BTW mppgf, medical officers or anyone else for that matter rendering aid at the site of an incident, may be sued. That is the common law right of the individual. Australia doesn't have the so-called 'good samaritan act'.
BUT to succeed, they must be able to prove a duty of care and subsequent negligence and injury. No action has yet been brought against a person whowithin the limits of their knowledge and ability, carries out actions that a reasonable person with the same level of skill and knowledge would carry out, acting in good faith and for the welfare of the injured party. Conversley, there does exist in Law substantial penalties for NOT rendering such aid as the individual is capable of doing in such a situation - not to mention the moral issues.
