A couple of answers:
Whilst I had done all the flight planning for the entire route before departure, Ewald and the pilot of the C208 did most of the day to day enroute planning with my input at times. Tracey was generally given the final result (or not, as Ewald knew it of course) - but was very rarely involved any planning. In her defence, she was usually very busy with the film crew and it would not have made sense (for the film) for her to be checking notams etc. I filed all the flight plans and GenDecs (Stearman POB:2) and paid all the charges etc. for both aircraft.
I wasn't bored! As well as the aviation side (including the AVGAS along the route) I was also dealing with film permits and paperwork, visas, ground transportation, hotels and restaurant bookings and managing the entire (also very large amounts of cash) budget (converting money to receipts!).
