Hi guys,
I'm not in charge of this discussion;

but, for what it's worth, I did say
competent... I'm not sure that the Brabazon and Princess quite achieve that soubriquet, due primarily to lack of power?
The weakness in my question may be that "failed" is a subjective term. For me, the
starshift10-quoted 56 Stratocruisers (about the same number as the too-small VC10) is getting darn close. I suppose you have to compare it with the opposition, to some extent? Was the Stratocruiser really too big, or were there other problems?
Keep them coming,
Chris
