You obviously have more technical knowledge than the BA Engineers that supports SCG so perhaps you could care to advise why you are more qualified to make this statement than they are, particularly when they believe it is possible.
No-one here has doubted the technical expertise of any engineers that may be associated with your group, so I consider that a bit of a red herring and I feel under no obligation to respond to it.
However, one does not need to be technically-qualifed or Concorde-rated to see that the undertaking that you propose will demand a quite considerable expenditure, possibly running into the millions of pounds, in terms of both initial funding and ongoing maintenance.
Perhaps you could give us an idea of your working costings and explain to us how your group plans to fund this expenditure?
