Favourite Aircraft on Infinite Flight

If there was suddenly some tragic news in the form that there could only be one aircraft left on infinite flight and all the rest had to be taken down, which would you choose and why? Also what would you want to have as your only region?

Thank you,

Concorde

oops sorry for putting it in the real aviation to begin with!

737-BBJ or 777-300 or 737-700

777-300 (later to a320) and I would only have the London region

Cessna 208

It’s already the A320 family (I can’t wait:D)

737-800 The best

A320 (when it comes out) and SoCal
