Its not as difficult as some would have you believe. I have done it quite a few times now in a variety of aircraft. Careful planning, watching the weather and ensuring the aircraft has the capability are key to success. If its a !!!! can VFR only on SEP then stick it in a container. If its a high performance IFR singe that has the legs or can be tanked its not a major eve if planned properly by an experienced ferry pilot.
