Just to add to my last, the 'saving life' Rule was designed to address the need to low fly if the a/c had a problem that needed that 'out', NOT to address the SAR/HEMS/Police use of an aircraft. This has been misunderstood for years. Before I get howled down about being wrong, the Rules of the Air changes sent out by the GA department of the CAA many months ago, addressed this and make it clear. If you look at the proposed change it removes that alleviation completely and relies instead on Article 84 of the ANO, as explained in the covering text.
Please excuse me while I duck from an incoming Hellfire from an Apache!!!
