Is this normal for new aircraft development?
About 2 years late and about 2 billion over budget?
Chief Executive Officer Alain Bellemare is trying to stop a cash drain after its C Series jetliner came to market more than two years behind schedule and about $2 billion over budget.
I suspect that it's within at least two sigmas, but maybe that's just not understanding the "how to get a new airliner to market" as well as I might .
I noted from that article that Bombardier's revenues from aircraft are abou 57% of the business.
