On my 6ft screen you can really get an idea of perspective. If you watch a studio show like QI you see how small the audience really is. In this case we can see how small the Space Shuttle really is. Wikipedia lists its height as 184.2ft. Using the people on the right hand side we can estimate that the shuttle is about 15 times the height of a man or around 90ft. Not very scientific but I don't think the shuttle, or at least the part we see launch, is anything like the size NASA say it is.
