I dont see haw describing the fleet as ageing will do a disservice to the RAF. Ok its true, I dont really know the current state, but those airframes & that 'technology' have been around a few years too long IMHO.
Of course, it may well be full of 'dramatisations' illustrating what happened (we even get those in toothbrush adverts these days), lets wait & see.
I'll watch it anyway, even if its just to shout 'Bo&&ocks' at the TV every time I think they get something wrong.
