Your 2-seat Typhoon comment should hopefully demonstrate that you know nothing of the jet, the people who support it, or the job(s) done by the few who are connected to it.
If you had a bit more knowledge, you'd know why the aeroplane is not in Afghanistan, how hard the people involved work on doing their jobs (just the same as everyone else in the Forces), and why the Jag and F3 needed replacing.
As for the idea that the RAF is considering getting more 2-seaters to do the job, it is not going to be too long before we see an all single-seat OCU as the 2-seaters run out of flying hours.
So there.
