I was back home with my parents and tried to rebuild all my old Lego. The train from 1996 was still working and Fort Legoredo looked as good as new.
But I wasn't able to find instructions online for the Space Shuttle and what looked like a Space research station, or part of it.
I will try to explain what it looked like as best as I can.(I'm back home in 2 weeks and cane make a picture then)
It looked like a small white Catapult, attached was a high see through Panel(blue) with different angles displayed and the arcs they would trace after they were launched.
It was to explain that 45° is the best angle to lauch something if you want to go for range.
Thanks for your time
