Care to elaborate on that? Sounds interesting..

Cannot really add anymore. I can only assume they tied up some sort of system whereby blue diesel was injected into the exhaust, on demand. Whether it was on both engines or not I wouldn`t know. Presumably it was a single seater. Unfortunately, I didn`t have my camera with me at the time but it must have been July 1969 as I was working on a fruit farm at the time picking strawberries!
Both practice displays took place at lunchtime (presumably a circuit embargo was in place for other aircraft)
.It was the usual seven minute display and the airfield and surrounding villages were covered in this blue haze! Strawbs stayed red though!
