I also see no issue with the post. They guy has been honest with purpose, he is ferrying an aircraft across the US for it to be onward ferried by some else for the atlantic crossing.
He wants company and a cost share. He has stated that the costs share is 50/50. He has stated that anyone who comes must be able to fly the aircraft so that clearly states that they will be logging P1 during their legs. He has stated that he will retain the overall decisions on routing weather etc as he is responsible for the aircraft, just like my group stating that we don't put the Malibu into grass.
He has been honest with his experience and as someone with many times his experience if I went along I would be happy with his terms for the flight.
All very upfront to my mind. If I can fit in the time between other trips I would be happy to go.
