Shoot the Programme Managers !!
My reason for querying the originally forecast date for 1st flight is that there's an irrefutable law in Programme Management that e.g if the 1st flight is,say, 1 year away then you might get away with a 3 month slip without being shot, if its 6 months then maybe 1 month would be permitted, 1 month maybe a week and a week away maybe a 1 day slip....on the day of the 1st flight if its posted for 1100 then its probably going to get airborne about 1500...I speak from personal experience (Sea Harrier FA2 & Avro RJ)....so basically Boeing Programme Managment has screwed up big time ( 1 week away 3 month slip)....just what were their Senior Managment doing -this must have been known as early as 1st quarter 2007. ChristiaanJ was spot on in this respect. The 1st delivery must be in question as earlier 'posters' have pointed out.....the other irrefutable law of Programme Management is if you've got a problem then the sooner you let your customer know the less painful in the long run it will be.
