Word from 17 (F) Sqn is that they love it. Despite it still having numerous restrictions and bugs, they are very impressed so far and can't wait to get away from their BAe 'nannies'.
Apparently, a couple of Typhoons gave a pair of F-15Cs a real shock recently. However, this was only 'see and avoid' coz their not cleared for any ACT yet!
