Yup - currently only 4 used A310s available worldwide. 3 x A310-324 with P&Ws for sale, 1 x A310-300 with CFs for immediate wet lease........
And yet in 1996 we were considering 24 or so
brand new A310MRTTs......
Used aircraft are not really the answer - it's new build which are needed. But since the MoD has
never bought a new tanker, always relying on someone else's cast-offs, the fast jet centric airships will still want their whizzy little pointy jets at the expense of all other capability.
