Your lordship -
Lord Farringdon.
The concepts of safety range CRM to Mantra; neither perfect, nor static. Change according to the last accident or academic concept, often a long time after the event with fading memories.
As much as current safety initiatives, operations, and training are ridiculed, remember that they have achieved the current high levels of safety - whatever the measure. However, the industry must not continue to expect the same methods to improve safety beyond what has been achieved - we keep on doing the same, but expect a different result.
Thats complacent.
Yes keep what we have, do not try to move the clocks back; look forward seeking small changes which might influence the future, change, check, be prepared to change again - if only we knew where to start.
