Disregarding false sectors (flying overhead etc) so as to achieve a 'record' could somebody tell me how the average VC10 times between BZZ and MPN compared with the 'chock-to-chock' times given in my post;
BZZ to ASI 8.20
ASI to MPN 7.30
MPN to ASI 7.30
ASI to BZZ 8.25
Having flown both the VC10 and the 747, I would put my money on the 747 being faster.
