Thanks so much for the replies I got now from several people.
Have managed to find a fantastic speaker for the event through this very thread, which shows the power of PPRUNE
Happy for anyone else to continue to get in touch though, as I am now looking at a follow-on event for next year with a more specific focus around risk themes and cross-learning between aviation and extractive industries.
Safetypee - will work my way through those references. Many thanks for posting!
