...and confirm these Tristars of yours are up to date with their checks!!??
Indeed they are....and several well known aviation authorities looked very carefully....including one in the EU.
Other than inadequate funding, there really can be no other reason why the RAF can't keep their TriStars (well, some of 'em anyway) totally serviceable.
These types are an older design and are rather easily maintained, provided a practical outlook is maintained....all it takes is knowledgeable expertise.
And, a little luck...
