REDTPI - well if it had been a 100% RAF effort, it'd have meant that JFH was only commemorating the efforts of 1 Sqn and the RAF exchange chaps on the SHAR in 1982. 50-50 seems a fair split (since you can't have 30% of an RAF pilot...)
I'm surprised there isn't a random picture of a VC10 accompanying the story, though. RAF News appear to be letting standards slip.
