hi mark

its still available on captain sim as a download £19.99

but clearly its been taken off just flight , it was there  ,

i dont understand why they do that ,  i dont expext a life time warranty lol,

just flight did the disc version of captains sims space shuttle,

all other just flight disc versions of other dlc works as do other brands,

it seems there was an issuse between JUST FLIGHT  and CAPTAIN SIM ,

ands as you have seen just flight instead of helping have just removed any trace now,

thats just sad as i now have 2 copies of space shuttle exspansion just flights disc version of captain sims SSE

and reading posts and reviews of the past for people who bought the disc version  ,
it was a 50/50 wether it would work or install or in quite a few cases break FSX completly, 

hence why you or i now cannot find anything,,

i will have to save and wait till i can afford CAPTAIN SIMS download version,

i even emailed a month or 2 ago , 1 of the games devoplers who still works for just fight , but sadly no reply   lol.
