Imagine if Melbourne Airport was to use the shorter 'decommissioned' control tower as a public observation tower, they could charge a huge entrance fee, you would get a ride up in the lift and a magnificent view of the airport, not sure how many levels it is, but they could put in a restaurant as well, the public could access it from the perimeter road and they could put parking there without too much interference. It could be the first airport in the world to do such thing, I could see it being a sensation for enthusiasts.

Could do the same to the old Sydney Tower.

Yeah, jazz it up, put in a revolving restaurant.

Best idea i have heard on this site. 

They do it in most big Airports in Germany, although from a dedicated area atop the terminas, not defunc Towers, but a good idea nontheless.

Forget about restaurant for the moment and say it would be only observation deck. How much you would pay? I would not pay more then $10 and probably it is not worth for them.

Though idea is nice - it should be implemented everywhere.

Its a great idea and I would love it to happen but someone would get in the way and get upset about security

Well it would be nice if they didn't charge huge entrance fees.
