Suck back, mixy blob and blow 4, always a contentious bunch of rules! A good station would have its ucker SOPs lined up next to 'pilots to see and Station standing orders'.
I seem to remember that ex 96 and 97 on the auth sheet was 'Uckers solo and pairs' (98 and 99 always being wazzing and zooming!).
Twas always a matlot inheritance as I understand it. First played the game in Khormaksar in '66 whilst hosting some strange chaps from Sheba (why do the fishies insist in calling a bit of land a 'ship'?)
