Complete non starter.
Yes the VC10 was a superb machine in its day but heavy ( much metal milled from the solid, plastic is the game these days ) and arguably over engineered. Not sure where the earlier poster got 6000 miles range, we struggled to get LHR _NBO non stop with a TOW of 152 tonnes ( ok 151953 for the purists !).
Thirsty, certainly. When I was on loan to GulfAir the despatcher showed me the TriStar fuel plan, almost exactly the same as our VC 10 with its 125 or so pax but with 300 or so on the 1011.
Was the VC 10 that fast in line ops. ? In BA we cruised at .84 imn .825 true, not that much faster than the B75/76 at .8 true. Burn per pax, vastly less on the Boeings.
Yes, she was a delight to fly and fly in but she’s had her day.
