I was at the factory to report on the "opening" and the facts about Le Bourget are these: Le Bourget organisers and Airbus marketeers would dearly love to have the A380 at the show and preferably to have it in the flying display - for obvious reasons. The Airbus people actually producing the aircraft say 'fine...but' all depends on how severe the effect is on the test-schedule, and how smoothly the schedule is going by then.
A personal bet: unless the programme has gone decidedly pear-shaped, it'll be there. Me too!
