I thought that the actual aircraft was registered as G-OIZI (i2i was the tv production company) and G-info shows it as having been registered to the producer.
The aircraft was certainly at Europa in 2003 still unfinished. When The original Europa company went bust in 2004, G-OIZI was sold by the liquidator to the owner of AFE. It seems to have since passed through two more owners and as the CAA now have sight of insurance it could be close to finally flying.
The actual aircraft used for the "first flight" sequence was G-CHET.
