Nulli-secundus; British Army Dirigible No 1, christened Nulli Secundus (Latin: "Second to none") was a Semi-rigid airship. First flown on 10 September 1907, it was Britain's first powered military aircraft.
I believe semi-rigid well describes Nulli and his anti-JetGo posts.
It's easy for him to sit back and shart all over every JetGo move. My guess would be that Nulli has been denied a JetGo interview or something of that nature. Maybe he has worked for the owners in a previous life or one of them boofed his missus, who knows and who really cares about his endless sniper attacks upon JetGo.
At the end of the day JetGo are giving things a shot. Time will tell if they are successful. If they aren't then Nulli can play with himself silly and prance around the pages of Pprune, penis in hand saying 'I told you so I told you so'. In the meantime lets hope JetGo succeeds as our industry is in bad enough shape as it is and even an expansion in the hot air balloon sector would be welcomed at this point in time.
