MBA is still using two Meteors Mk 7 (and a half) for the air testbed at Chalgrove. One is gloss black and one is silver with orange panels.
You can read all about them on my ejector seat website:

The hunter and Canberra are no longer used. The Canberra was last used to test the Mk9 seats for the jaguar and harrier back in the 70's and the nose of that aircraft is now in the Farnborough museum.
I would also love to add more recollections of ejections to my site. Please get in touch if you're like to contribute.
