I checked and 3088 indeed carry FW74 marking but 3074 carry FW31 marking (unless been reassigned)

I wonder about two other things:
1. Four of the five participants got 5th generation capability (US, UK, Italy, Israel), will they use it in the exercise (at least by US and UK)?
2. The US airplanes will come from Lakenheath and/or anywhere else?
