This sort of thing was one of the original fundamentals of ATr's business model so I'm glad to see them closing this deal.
I must admit however that I find it odd that they're leasing out a tanker airframe. I thought it would've been one of the pure pax/cargo aircraft? Admittedly UK Plc probably has little or no use for the original number of tankers planned but I would've thought a tanker variant wouldn't make a particularly tempting option for a commercial operator. Whilst the KC2 doesn't have a fuselage refuel point surely there is a fair bit of associated plumping etc that, for a civilian operator, is just dead, revenue-stealing weight. Or can it all be easily removed?
