A certain balloonist who was part of the team who circumnavigated the globe in the Breitling Orbiter has P1 RTW (Pilot 1, Round The World). Very well earned.
Just along from where I lived in London was a famous actor with two Bentleys. The number plates were 2B and NOT 2B
I always wanted G-SPOT on a balloon as the retrieve crew would be forever trying to find it. I do want G-OFYS on the current toy .
