 The following is a direct quote from the Spitfire II Pilots notes.

 (i) High speed in the dive. This, coupled with the fact that the very effective elevator control, and comparative instability in pitch of this aeroplane, makes it very easy for the pilot to impose high load factros, or ""g"", when looping, doing tight turns, or pulling out of the dive. Altough the safety factor of the aeroplane is about 10, it is well within the pilot's power ""10g""; the wings would certainly fail is this figure is much exceeded. In very bumpy atmposphere... etc. etc.

 Everybody is free to make his own conclusion and wheter the other accusations, to which I do not even bother to reply, have any sort of credibility. They are, in my opinion, the struggling of an aircraft fan against referenced, documented, verifiable facts by all means available for some time now. Baseless accusations do not make good contributions.
