A comment? I don´t believe it until I see the StarLiner 70 and 90 rolling out of the hangar.
Have them flying in 2003 already means that they are earlier on the market than the ERJ-190-100/-200 but the 928JET and CRJ900 will be there before. The launch of both planes is immanent, the CRJ900 and 928JET will be most likely launched in the 4th quarter 2000 and I suppose that then the launch orders will be announced. Likely customers: Air Nostrum, Eurowings, Comair, Southern Winds just to name a few.
The have LoIs for 30 planes from at least three companies? Gee, what a lot. As far as I remember Fairchild still has 47 728JET in its books as a LoI (Eurowings 30, Proteus Air 15, Sol Air 2). And they will be cheaper than the ERJ-170/-190/728JET/928JET? Means they cost about 24-26 millions each.
When they claim to be more comfortable they have to seat 5 abreast in a tube at least 134.5 inches wide to match the BAe146/ARJ/ARJX. The ERJ will have 108, the 728JET 128 inches width. Let´s see this plane.
Conclusion? A "bit" too ambitious. Having build a factory next year and THEN start a new project? Have they already started building this factory? Have they already started development of these aircrafts? Have you heard anything who these customers are? Some questions to answer...
