Doing a search on the BBS boards, you will find other threads requesting the Gloster Meteor's inclusion to the game. You will also find that the reason why the Meteor has not been added is because it is so low on the priorities list. There are more aircraft that need to be added- particularly the EW and MW planes.
That being said, I would not mind seeing the Meteor in the game. But only until more important aircraft have been added first.
