Fires
I don't blame RFS or any fire fighting agency from requiring a pilot to show and demonstrate his qualifications, not to mention that the aircraft is properly equipped and serviced, and the pilot is current and experienced.
RFS put lots of their ground and observers etc on their CRM courses so those personnel should know something about the process. If your sitting alongside another person for hours, use him or her. Even if you say just one thing to him say "Call every wire you see, every time you see it". you will be well ahead.
