RE:Potential revenue stream How much savings can there be to change the wings and engines? Why not just convert the 8000 to commerical operations and lower the sales price such that the profit is the same as it would have been had you gone ahead and changed the wings and engines? If you're afraid of cannibalizing business jet sales and resale values, just subsidize the lease as long as the aircraft is used for commerical operations. Also, what is the point of lowering the product cost and range to compete with Embraer when you can sur/pete (from Edward De Bono) with a product that Embraer CANNOT compete with? Also, less R&D that way so if it doesn't work out, you're out a lot less $$$. Can try routes like YVR-MIA or Toronto - Lima. Just my amateur opinion.
