I'm getting the feeling we are "testing" Gulfstream. I don't know the specs of the 250, but if it's the size of the 200, I can't see that replacing the Falcon.
Piaggio? Doubt it. We are trying to streamline the product and reduce the number of OEMs. Embraer may well be working on a mid size that would foot the bill for Netjets US. It will all come down to reliability and cost. Something that was lost on our previous leadership. There was way too much emotion involved in the purchases made last decade.
Legacy 450/500. Embraer is giving massive discounts to sell their product right now.
No way on the 250.
