Hey notso,
I've seen many a post from you on pprune so perhaps I should feel honoured to be flamed by such a celebrity!
To answer your questions - to you I guess it doesn't matter and no I'm not after anybody. It is simple curiosity - hence I posted in the Spotters forum. Since I work in the industry I was interested in identifying said aircraft but couldn't do so myself and hoped someone could inform me what it was. Note I worded my question carefully, saying it was of bizjet proportions - I rather thought it wasn't actually a bizjet however.
Could it have been something practicing for a Farnborough
