Nick,
I think you missed the point....it was not the length or duration of the flight(s) but rather the darn thing did not break down along the way....after all...5,000 miles without a breakdown is pretty impressive.
I have a fleet of 11 aircraft that averages about a 98% availability rate yearly...and that includes two aircraft that go logging every day....but then we don't intend to haul the Number 1 Boss Fellah.
