Pay peanuts, get monkeys.
An "experienced" ferry company should know better then to subcontract to another "ferrycompany" only because they were half price, couple that with RW's decision to bring along a 13,000 hour "friend" should have raised more red flags then the Kremlin has on May day.
This either shows that the ferry business is extremely cut throat or has no due dilligence in place, a faxed copy of RW's FAA license would have quickly shown that he does not hold Multi Engine Instrument privileges.
I do wonder if the insurance company ever paid out on this one, if so maybe they should be directed towards RW.
