Er..bit out on the old calendar TS,
Dishcloth from Summer 03 - Summer 04 ish
Whatashame first unit Summer 04 - Summer 05 ish, might be a bit earlier, with a bit of cut and paste.
First possible en masse flock of AH around the DUA in the dark, about late 05, if you are lucky..WFM hits about the same time. Might see less of the type airborne than expected.
Eraser,
Best get some bloody good night vision binos, as most crew time will be spent in the FDS (Sim)
