For myself - I wish! A Chipmunk and Yak 52 are my usual mounts.
But I have flown on the flight deck of BA Concorde G-BOAD from take off to landing, including mach 2.02 at 60,000. It was quite an experience. I was in the jump seat immediately behind the captain, was wearing a white shirt, and as the passengers came forward in pairs for cockpit visits most of them did take me for one of the crew ;~)
I wrote an article about it for 'Pilot' and it was published a couple of years back.
Such a trip would not be possible, I guess, in these post 11/9 days.
