If the Lancaster goes tech today it will be extremely embarassing for the boys in blue; for the 'airborne spares' which I assume to be a Tiffie & Tonka will do little to make up the deficit.
I know that the elastic has snapped, but this example of RAF on parade is IMHO a disgrace, and if political, there are other ways to make the point without looking like dicks in front of the entire world. A couple of diamond fours from the training world would have / could have made a difference.
