Blind pilot rescued by RAF?

I think they've got this wrong. The Toucano was scrambled from Linton on Ouse and that couldn't have got anywhere near him at that height and in that time scale as at the time he was taken ill he was near Pocklington. The WC then guided him back over York to Linton and after a couple of bounces got him safely down on the third attempt. I wonder why they didn't try at Elvington which has one of the longest runways in europe and wasn't in use on that day?
