The last time I saw Meteors being flown by an RAF unit was when I was at Changi. In 1971, I watched as 1574 Target Facilities Flight's Meteors were being broken up and carted away. The Singapore Armed Forces didn't want them and they were certainly not going to be flown back to Blighty, so they were scrapped on site. I believe civilians flew them as target facilities aircraft in UK for a while after that, but there were no more in proper RAF service.
There was a Meteor at Chivenor in the very early 1970s, flown by Flt Lt Bill Arrowsmith and used to train army FACs and ACOs.
