Not that interested in flying to be honest, that doesn't stop me from appreciating a good bit of engineering/design though.
How about a good solid bit of British ingenuity - mach 5 air travel anyone?
Just a shame that, being British, there will be no investment and the project will remain a dream until someone from another country builds their own version...

If I were to own a plane myself, it would probably have to be an F22/24 Spitfire. Teardrop canopy & 5 bladed prop - the finest expression of one of the best looking planes of all time.
