Whilst I have no wish to "rain on the parade" it does strike me, having looked at the crew list, that the only pilot in current flying practice on a large aeroplane is Martin Withers.
The skills of the others are, or perhaps were, beyond reproach, but I would have thought it prudent, bearing in mind the aircraft will be displayed, to stick to guys with ATPLs, in current flying practice on large airliners, who previously flew the aircraft.
