Just been from my hometown of Armidale to our nations capital Canberra for work, which requires changing planes in Sydney. Both Sydney & Canberra have an historic aircraft on display in the terminals. The Sydney one has been there for a few years now (and from the pic below, you can work out where ''QANTAS'' came from), but the Canberra one is newish. What is on display in your airports?
And next time I'm at Tamworth airport I'll have another one.
