It may be, but the question is would they be better than nothing?
This government (and the one that follows it) is hardly likely to announce a procurement program for new aircraft any time soon, rather they'll keep chipping away as much as they can.
Whilst many are critical of the Tristars they have performed many years of valued service even though they were brought as a stop-gap.
Yes it'd be great to have an order placed for something perfect and brand-new but as I said, its not going to happen, no matter how much you and I argue the point on here.
So the question is, if the MoD could purchase them as a 'stop gap', would they be better than nothing?
