Buran was in Sydney 15 years ago during the Olympics.Had a good look around it,pretty impressive.I walked inside the cargo bay and up to the flight deck to see everything up close.It was one of the test models:
Is the Buran that was on display in Sydney a real space Buran?
No, it is the aerodynamic tester Buran OK-GLI. It never flew in space nor was it designed to. It was, however, used to conduct tests on the automatic landing system for the eventual space orbiters, as such it flew in the low atmosphere. That's what it needed the engines for - so that it could get up to a height of around 5000 metres and practice landing approaches. It’s back in Moscow now btw.
